ABSTRACT : The antifungal activity of dichloromethane extrct of Olea cuspidate and Olea glandulifera was
investigated against Candida albicans and Aspergillus niger. The plants were extracted with dichloromethane
and antifungal screening of this extract was done by disc diffusion method. Flavonoidal compounds were
present in dichloromethane fraction and it is reported that flavonoidse responsible for antifungal activity. The
diameters of inhibition zones were used as a measure of antifungal activity and resulting zone of inhibition was
measured around the disc with transparent scale in millimeters.
KEY WORDS: Olea cuspidate, Olea glandulifera, Candida albicans and Aspergillus niger
I. INTRODUCTION
Olive tree (Olea europaea L.) is one of the most important fruit trees in Mediterranean countries, where
they cover 8 million ha, accounting for almost 98% of the world crop (Pereira et. al, 2007). Historically, Olive
leaf extract has been widely used in folk medicine for combating fever and other diseases such as malaria
(Banavente- Garcia et. al., 2000). Olive leaf extract has the capacity of lower blood pressure in animals(Khayyal
et. al., 2002) and increases blood flow in coronary arteries, relieves arrthythmia and prevents intestinal muscle
spasms (Zarzuelo, 1991). Phenolic compounds isolated from Olive fruit have been shown to inhibit the growth
of Eschesrichia coli, Klebslella pneumonia and Staphylococcus aureus( Aziz et. al., 1998; Yigit et.al.,
2001).Gourama and Bullerman, (1987), tested the effect of oleuropein on growth and aflatoxin production by
aspergillus parasiticus and found that Oleuropein stimulated mold growth but inhibit the production aflatoxin.
Sousa et. al.(2006) reported that the determination of phenolic compounds in „alcapurra‟ table olives and
evalution of their extract in vitro activity against gram positive, gram negative bacteria and fungi(Candida
albicans and Cryptococcus neoformans). Some aldehydes obtained from olive fruit revealed antifungal activity
against Tricophyton mentagrophylus, Microsporum canis and candida Spp. (Battinelli et. al., 2006). Phenolic
compounds within olive leaf extract have shown antimicrobial activities against several microorganisms
including: Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Bacillus cereus, Salmonella typhi
and Vibrio parahaemolyticu (Owen et. al., 2003).
Olea cuspidata is found in the Himalayas from Kashmir to Kumaun upto 2400 m altitude. According to
Chopra et al, 1986 Olea glandulifera was distributed in N.W. Himalayas 2000-6000 ft. from Kashmir to Nepal,
N. circars hills of ganjam and Vizagapatam, Deccan, Maysore and W. ghats of Madras State.Pathogenic fungi
and bacteria cause different types of human diseases and shows adverse effect on human health. Skin, hair, nail
and subcutaneous tissues in human and animal are subjected to infection by several organisms, mainly fungi
named dermatophytoses( Valeria et. al., 1996; Amer et. al., 2006). As it is clear from the literature Olive have
antifungal activity against disease causing fungi. Thus, the main objective of this study was to investigate
antifungal activity of extracts from Olea cuspidata and Olea glandulifera species.
II. MATERIALS AND METHODS:
2.1.Collection of plant material: For antifungal screening plant material (Olea cuspidata) was collected from
NCC ground Almora and Olea glandulifera was collected from Govind Ballabh Pant Institute of Himalayan
Environment and Development,Koshi,Katarmal(Almora) .
2.2.Preparation of crude extract: The dried powdered leaves of plant material (Botanically identified) were
extracted sequentially extracted with 50% aq. EtOH by Cold Percolation methods. The H2O-EtOH extract was
concentrated under reduced pressure at 400
C in Rota-evaporator until only H2O layer (approx. 50 ml.) remained
the aqueous layer was partitioned successively with CH2Cl2. Dichloromethane extract with different
concentration was examined for antifungal test by standard disc diffusion assay Murray et.al., 1995.
The undiluted plant extract was diluted, whether required in N.S.S. (Normal Saline Solution). The standard
procedure suggested by Cruiskshank et al, 1975, was followed to make serial two fold dilution-

[1] Five clear sterile cotton pluged test tubes of medium size were taken in duplicates and marked as 1-5.
[2] Using aspectic techniques, 5 ml of NSS was taken into all five tubes.
[3] The first tube, 5 ml solution (200gm/ml) of the plant leaf extract was added ; contents of the tube were
mixed properly by pipetting.
[4] From first tube, 5ml 0f suspension was transferred to second tube, mixed well and again 5 ml suspension
was transferred from second to the third tube.
[5] This process was continued up to tube number five and 5 ml solution from the last tube was discarded. tn
this way two series of two fold dilution was prepared , one serve as a test series and another serve as a
parallel control. Thus, the dilution obtained were as 1:2, 1:4, 1:8, 1:16, 1:32. Same procedure was applied
for Olea glandulifera and Olea pendolino.
TEST FUNGI: The antifungal activity plant extract was assessed against two fungi- Candida albicans and
Aspergillus niger. The sources and details of culture are shown in the table No.-1

2.3.Antifungal Assay (Disc Diffusion Method): Determination of antifungal activity of sample extracts was
accomplished by agar disk diffusion method. The dried extracts were dissolved in NSS to a final concentration
of two fold dilution of dichloromethane fraction. Antifungal tests were carried out using the disc diffusion
method reported by (Murray et.al., 1995) and employing 100 μl of suspension containing 104 spore / ml of
(Candida albicans and Aspergillus flavus) on the Potato Dextrose Agar. PDA was autoclaved at 15 b pressure.
PDA plates were allowed to solidify for 5 minutes and inoculums suspensions were transferred through strelized
loop on PDA plates. The sterile disks (10 mm in diameter) impregnated with 5μl of the extracts solution
(equivalent to 12.5, 25, 50,100 and 200 mg /disc) and NSS (as negative control) were placed on the inoculated
agar. The inoculated plates were incubated for 72 h at 30° C. The evalution of antifungal activity was carried out
in triplets. The diameters of inhibition zones were used as a measure of antifungal activity and resulting zone of
inhibition was measured around the disc with transparent scale in millimeters.
2.4.MINIUM INHIBITORY CONCENTRATION (MIC Assay): Minimum Inhibitory concentration of the
positive extract was determined by the method suggested by Scott (1989). By this method, test organism were
seeded uniformly over an agar surface and exposed to decreasing concentrations (200 mg/ml to 12.5 mg/ml) of
plant extract diffusing from paper disc (Disc diffusion Test). The plates were then incubated at 37ºC for 18
hours. The fungi were sensitive to plant component they were inhibited from growing in a circular zone around
the paper disc, Zone of inhibition was measured in mm with a “HI Antibiotic Zone Scale”.Antifungal activity

It is clear that, the plant extract shows antifungal assay when the concentration of dichloromethane was
increased. It is also clear that plant extract have maximum antifungal activity against Candida albicans(
inhibition zone 24 mm) and Aspergillus niger. (Inhibition zone 21 mm).Minimum Inhibitory Concentration
(MIC) for extract ranged from 25 mg/l to 50 mg/l. It is also clear that plant extract have minimum MIC for
Candida albicans with 12 mm but in case of Aspergillus niger with 16mm. In is clear from this study that
dichloromethane extract of Olea Species, possessed antifungal activity. This further supports the traditional
medicinal uses of this plant for the various infectious diseases caused by fungi. Result of antifungal activity
shows that higher concentration of dichloromethane extract was more effective against fungi. Although
individual phenolic compound in Olive extract may show strong in vitro activities, the antioxidant and
antimicrobial activities of combined phenolics showed similar or better effects than the individual phenolics
(Lee and Lee, 2010).Owen et al, 2003, further supported that extracts may be beneficial than isolated
constituents since a bioactive components can change its properties in the presence of other compounds present
in the extract. Certainly the chemical composition of the Olive extracts impacted the antimicrobial effects
observed. (Denyer, 1998). In fact the mode of action of phenolics has been shown to be concentration dependent
(Furneri et al, 2002).

IOSR Journal Of Pharmacy (e)-ISSN: 2250-3013, (p)-ISSN: 2319-4219 Www.Iosrphr.Org Volume 3, Issue 5 (June 2013), Pp 10-13 10 Antifungal Activity Of Olea Cuspidata And Olea Gladulifera Linn. 1, Preeti Majgaine , 2, D.L.Verma 1,2, Department of Chemistry, Kumaun University, S.S.J. Campus, Almora ABSTRACT : The antifungal activity of dichloromethane extrct of Olea cuspidate and Olea glandulifera was investigated against Candida albicans and Aspergillus niger. The plants were extracted with dichloromethane and antifungal screening of this extract was done by disc diffusion method. Flavonoidal compounds were present in dichloromethane fraction and it is reported that flavonoidse responsible for antifungal activity. The diameters of inhibition zones were used as a measure of antifungal activity and resulting zone of inhibition was measured around the disc with transparent scale in millimeters. KEY WORDS: Olea cuspidate, Olea glandulifera, Candida albicans and Aspergillus niger I. INTRODUCTION Olive tree (Olea europaea L.) is one of the most important fruit trees in Mediterranean countries, where they cover 8 million ha, accounting for almost 98% of the world crop (Pereira et. al, 2007). Historically, Olive leaf extract has been widely used in folk medicine for combating fever and other diseases such as malaria (Banavente- Garcia et. al., 2000). Olive leaf extract has the capacity of lower blood pressure in animals(Khayyal et. al., 2002) and increases blood flow in coronary arteries, relieves arrthythmia and prevents intestinal muscle spasms (Zarzuelo, 1991). Phenolic compounds isolated from Olive fruit have been shown to inhibit the growth of Eschesrichia coli, Klebslella pneumonia and Staphylococcus aureus( Aziz et. al., 1998; Yigit et.al., 2001).Gourama and Bullerman, (1987), tested the effect of oleuropein on growth and aflatoxin production by aspergillus parasiticus and found that Oleuropein stimulated mold growth but inhibit the production aflatoxin. Sousa et. al.(2006) reported that the determination of phenolic compounds in „alcapurra‟ table olives and evalution of their extract in vitro activity against gram positive, gram negative bacteria and fungi(Candida albicans and Cryptococcus neoformans). Some aldehydes obtained from olive fruit revealed antifungal activity against Tricophyton mentagrophylus, Microsporum canis and candida Spp. (Battinelli et. al., 2006). Phenolic compounds within olive leaf extract have shown antimicrobial activities against several microorganisms including: Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Bacillus cereus, Salmonella typhi and Vibrio parahaemolyticu (Owen et. al., 2003). Olea cuspidata is found in the Himalayas from Kashmir to Kumaun upto 2400 m altitude. According to Chopra et al, 1986 Olea glandulifera was distributed in N.W. Himalayas 2000-6000 ft. from Kashmir to Nepal, N. circars hills of ganjam and Vizagapatam, Deccan, Maysore and W. ghats of Madras State.Pathogenic fungi and bacteria cause different types of human diseases and shows adverse effect on human health. Skin, hair, nail and subcutaneous tissues in human and animal are subjected to infection by several organisms, mainly fungi named dermatophytoses( Valeria et. al., 1996; Amer et. al., 2006). As it is clear from the literature Olive have antifungal activity against disease causing fungi. Thus, the main objective of this study was to investigate antifungal activity of extracts from Olea cuspidata and Olea glandulifera species. II. MATERIALS AND METHODS: 2.1.Collection of plant material: For antifungal screening plant material (Olea cuspidata) was collected from NCC ground Almora and Olea glandulifera was collected from Govind Ballabh Pant Institute of Himalayan Environment and Development,Koshi,Katarmal(Almora) . 2.2.Preparation of crude extract: The dried powdered leaves of plant material (Botanically identified) were extracted sequentially extracted with 50% aq. EtOH by Cold Percolation methods. The H2O-EtOH extract was concentrated under reduced pressure at 400 C in Rota-evaporator until only H2O layer (approx. 50 ml.) remained the aqueous layer was partitioned successively with CH2Cl2. Dichloromethane extract with different concentration was examined for antifungal test by standard disc diffusion assay Murray et.al., 1995. The undiluted plant extract was diluted, whether required in N.S.S. (Normal Saline Solution). The standard procedure suggested by Cruiskshank et al, 1975, was followed to make serial two fold dilution-
  • 2. Antifungal Activity Of Olea… 11 [1] Five clear sterile cotton pluged test tubes of medium size were taken in duplicates and marked as 1-5. [2] Using aspectic techniques, 5 ml of NSS was taken into all five tubes. [3] The first tube, 5 ml solution (200gm/ml) of the plant leaf extract was added ; contents of the tube were mixed properly by pipetting. [4] From first tube, 5ml 0f suspension was transferred to second tube, mixed well and again 5 ml suspension was transferred from second to the third tube. [5] This process was continued up to tube number five and 5 ml solution from the last tube was discarded. tn this way two series of two fold dilution was prepared , one serve as a test series and another serve as a parallel control. Thus, the dilution obtained were as 1:2, 1:4, 1:8, 1:16, 1:32. Same procedure was applied for Olea glandulifera and Olea pendolino. TEST FUNGI: The antifungal activity plant extract was assessed against two fungi- Candida albicans and Aspergillus niger. The sources and details of culture are shown in the table No.-1 TABLE 1: DETAIL OF FUNGAL SOURCES PROCURED S.No. Microbial Strain Strain designation/Lab code Source 1 Candida albicans MITC 183 IMTECH Chandigarh 2 Aspergillus niger MITC 281 IMTECH Chandigarh 2.3.Antifungal Assay (Disc Diffusion Method): Determination of antifungal activity of sample extracts was accomplished by agar disk diffusion method. The dried extracts were dissolved in NSS to a final concentration of two fold dilution of dichloromethane fraction. Antifungal tests were carried out using the disc diffusion method reported by (Murray et.al., 1995) and employing 100 μl of suspension containing 104 spore / ml of (Candida albicans and Aspergillus flavus) on the Potato Dextrose Agar. PDA was autoclaved at 15 b pressure. PDA plates were allowed to solidify for 5 minutes and inoculums suspensions were transferred through strelized loop on PDA plates. The sterile disks (10 mm in diameter) impregnated with 5μl of the extracts solution (equivalent to 12.5, 25, 50,100 and 200 mg /disc) and NSS (as negative control) were placed on the inoculated agar. The inoculated plates were incubated for 72 h at 30° C. The evalution of antifungal activity was carried out in triplets. The diameters of inhibition zones were used as a measure of antifungal activity and resulting zone of inhibition was measured around the disc with transparent scale in millimeters. 2.4.MINIUM INHIBITORY CONCENTRATION (MIC Assay): Minimum Inhibitory concentration of the positive extract was determined by the method suggested by Scott (1989). By this method, test organism were seeded uniformly over an agar surface and exposed to decreasing concentrations (200 mg/ml to 12.5 mg/ml) of plant extract diffusing from paper disc (Disc diffusion Test). The plates were then incubated at 37ºC for 18 hours. The fungi were sensitive to plant component they were inhibited from growing in a circular zone around the paper disc, Zone of inhibition was measured in mm with a “HI Antibiotic Zone Scale”.Antifungal activity Olea cuspidata, against two fungal strain- Candida albicans and Aspergillus niger is summarized in the table No.-3(Fig-A and B) TABLE 2: MEAN INHIBITION ZONE DIAMETER OBTAINED BY LOADED DISC (Olea cuspidata) WITH 5 mg EXTRACT DISSOLVED AGAINST DIFFERENT FUNGAL STRAIN Different concentration of plant extract(mg/l) Test Fungi Candida albicans Aspergillus niger Status ZD(mm) SEM Status ZD(mm) SEM 200 A 26±1.632 A 22±1.699 100 A 21±1.699 A 20±1.632 50 A 18±1.247 A 13±1.699 25 A 12±0.816 N 11±1.247 12.5 - - - - Key to tables: Symbole Meaning A active N Non Active ZD Zone diameter (-) No effect SEM Standard error of Mean
  • 3. Antifungal Activity Of Olea… 12 It is clear that, the plant extract shows antifungal assay when the concentration of dichloromethane was increased. It is also clear that plant extract have maximum antifungal activity against Candida albicans( nhibition zone 26 mm) and Aspergillus niger. (Inhibition zone 22 mm).Minimum Inhibitory Concentration (MIC) for extract ranged from 25 mg/l to 50 mg/l. It is also clear that plant extract have minimum MIC for Candida albicans with 12 mm but in case of Aspergillus niger with 11mm..Antifungal activity Olea glandulifera, against two fungal strain- Candida albicans and Aspergillus niger is summarized in the table No.- 3(Fig-C and D) TABLE 3: MEAN INHIBITION ZONE DIAMETER OBTAINED BY LOADED DISC (Olea glandulifera) WITH 5 mg EXTRACT DISSOLVED AGAINST DIFFERENT FUNGAL STRAIN Different concentration of plant extract(mg/l) Test Fungi Candida albicans Aspergillus niger Status ZD(mm) SEM Status ZD(mm) SEM 200 A 24±1.247 A 21±1.247 100 A 21±2.045 A 20±0.816 50 A 18±1.690 N 16±1.699 25 A 12±0.9428 - - 12.5 - - - - Key to tables: Symbole Meaning A active N Non Active ZD Zone diameter (-) No effect SEM Standard error of Mean It is clear that, the plant extract shows antifungal assay when the concentration of dichloromethane was increased. It is also clear that plant extract have maximum antifungal activity against Candida albicans( inhibition zone 24 mm) and Aspergillus niger. (Inhibition zone 21 mm).Minimum Inhibitory Concentration (MIC) for extract ranged from 25 mg/l to 50 mg/l. It is also clear that plant extract have minimum MIC for Candida albicans with 12 mm but in case of Aspergillus niger with 16mm. In is clear from this study that dichloromethane extract of Olea Species, possessed antifungal activity. This further supports the traditional medicinal uses of this plant for the various infectious diseases caused by fungi. Result of antifungal activity shows that higher concentration of dichloromethane extract was more effective against fungi. Although individual phenolic compound in Olive extract may show strong in vitro activities, the antioxidant and antimicrobial activities of combined phenolics showed similar or better effects than the individual phenolics (Lee and Lee, 2010).Owen et al, 2003, further supported that extracts may be beneficial than isolated constituents since a bioactive components can change its properties in the presence of other compounds present in the extract. Certainly the chemical composition of the Olive extracts impacted the antimicrobial effects observed. (Denyer, 1998). In fact the mode of action of phenolics has been shown to be concentration dependent (Furneri et al, 2002). REFERENCES: [1] Amer S, Aly MM, Sabbagh S, 2006.
