 Single- or double-compound
quills,
 1 m length, 0.5 mm thickness, and
6 to 10 mm diameter.

brown colour having longitudinal
lines of pericyclic fibre and scars
and holes
 The inner surface is darker than
the outer.
 Odour - fragrant perfume
 Taste - aromatic and sweet.

and Cassia by microscopical and chemical characteristics
Materials required:
Compound microscope, Microscopic slide, cover-slip,
dissection needle, zero number paint brush, watch glass,
a sharp razor blade, a beaker full of water, filter paper
Chemicals required:
Concentrated Hydrochloric acid, Phloroglucinol,
Glycerin

6.  Transverse and Longitudinal sections
 Steps involved
Section cutting
Staining
Mounting

7.  Three to four layers of horse shoe
shaped sclereids with starch
grains
 The pericyclic fibres present on
the outer margin.
 Completely collapsed sieve tubes
arranged tangentially;
 lignified phloem fibres, arranged
as tangential rows of four to five
cells;
 biseriate medullary rays with
needle-shaped calcium oxalate
crystals;
 longitudinally elongated idioblast
consisting of volatile oil;

8.  Outer Periderm and cork present
 Cortex consists of 10 to 15 layers
of parenchyma with sclereids
 Characteristic of lignified and
pitted sclereids
 The secondary phloem consist of
phloem parenchyma which is
thin-walled, containing abundant

10. Cinnamon Cassia
 10% of volatile oil, tannin,
mucilage, calcium oxalate and
sugar.
Volatile oil contains
 50 to 65% cinnamic aldehyde,
 5 to 10% eugenol,
 terpene hydrocarbons and
 small quantities of ketones and
alcohols.
 1 to 2% of volatile oil.
 80 % cinnamyl acetate,
 cinnamic acid,
 caryophyllene,
 phenylpropyl acetate,
 orthocumaric aldehyde,
 coumarin, tannic acid, and starch.
Eugenol is absent.
 The value of the drug depends on
the percentage of cinnamic
aldehyde present in it.

11. Cinnamon Cassia
 A drop of volatile oil is dissolved
in 5 ml of alcohol and to it a drop
of ferric chloride is added, A pale
green colour is produced.
 The alcoholic extract is treated
with phenyl hydrazine
hydrochloride, it produces red
colour due to the formation of
phenylhydrazone of cinnamic
aldehyde.
Note: Cinnamic aldehyde gives
brown colour with ferric
chloride, whereas eugenol gives
blue colour.
 With ferric chloride gives brown
due to the presence of cinnamic
aldehde and absence of eugenol.
 Cassia gives a deep blue black
colour with tincture of iodine
 Cassia oil contains coumarin
which gives strong green blue
fluorescence on addition of alkali.
