SARJA (Exudate)
Sarja consists of resinous exudate of Vateria indica Linn. (Fam. Dipterocarpacem), a large, evergreen tree, upto 30 m high with a cylindrical bole, indigenous to the evergreen forests of the Western Ghats from North Kanara to Kerala and also extensively planted as an avenue tree in Karnataka; resinous exudate is obtained by making semicircular incisions on the stem through the cork cambium up to the surface of sapwood.

DESCRIPTION
a) Macroscopic
Rough, irregular, solid, brittle masses, breaking into angular pieces, upto 1.5 cm thick, light-yellow to pale yellow in colour; odour fragrant; tasteless.
b) Microscopic
Slightly soluble in alcohol in which it forms ajelly-like mass; insoluble in petroleum ether (40oC-60oC), forming white precipitate; insoluble in carbon-disulphide but yields jelly-like mass, dissolves entirely and gives a dense red colour with concentrated sulphuric acid; dissolves mostly in chloroform giving white or milky solution; (Sal resin dissolves almost entirely in petroleum ether forming a pale cream solution and also dissolves entirely in carbon-disulphide). Test for presence of Colophony – (Distinction from Sala and Shallaki resin)
1. Dissolve 0.1 g in 10 ml of acetic anhydride by gentle heat, cool, and add I drop of sulphuric acid; a bright purplish-red colour, rapidly changing to violet, is produced.
2. Shake 0.1 g of powder with 10 ml of light petroleum (b.p. 50o-60o), and filter; shake 5 ml of the filtrate with 10 ml of dilute solution of copper acetate; the petroleum layer assumes a bright bluish-green colour.
