DESCRIPTION
a) Macroscopic
Roots of varying sizes and thickness, thin pieces show somewhat smooth brownish exterior, thick pieces tough and woody, light brown in colour, rough, longitudinally striated, lenticellate and with circular root scars; fracture fibrous; rootlets and branches, thin and somewhat fibrous; odour, nil; taste, pungent, bitter and astringent.
b) Microscopic
T.S. comprises of 6 to 9 layers of cork cells, a single layer of phellogen and usually 10 to 12 layers of phelloderm; cortical cells thin walled and tangentially elongated, containing circular starch grains, rosette crystals of calcium oxalate found scattered; a wide zone of secondary phloem consisting of sieve tubes, companion cells and phloem parenchyma present, traversed by medullary rays containing circular starch grains; resin canals present; secondary xylem a wide zone comprising of xylem vessels, tracheids, fibre-tracheids and fibres.
Powder – Creamish brown when fresh turning greyish brown on storage; shows under microscope, cortical cells parenchymatous filled with circular starch grain measuring between 3 to 16 n in diameter; brown colouring matter and rosette crystals of calcium oxalate present; vessels, tracheids, xylem parenchyma, fibres and fibre tracheids present; vessels, drum shaped, pitted with large end perforations; tracheids, much longer than wide with bordered pits; fibres having pointed ends; fibre tracheids, having blunt ends and a few oblique pits.
IDENTITY, PURITY AND STRENGTH

Acid-insoluble ash Not more than 0.8 per cent, Appendix 2.2.4.
Alcohol-soluble extractive Not less than 4 per cent, Appendix 2.2.6.
Water-soluble extractive Not less than 8 per cent, Appendix 2.2.7.
T.L.C.
T.L.C. of methanolic extract of the roots on precoated silica gel G plate using methanol – chloroform (20 : 80) showed a blue fluorescent spot under UV (365nm) along with number of other spots of very weak intensity. Due to the presence of very negligible amount of alkaloids in the roots these could not be isolated. However, methanolic extract of A. nervosa seeds was prepared and T.L.C. compared with A. nervosa roots extract. The T.L.C. pattern of root and seed extracts (prepared in methanol) was similar although the intensity of spots in case of root extracts was very poor.
