Physicochemical and Phytochemical standardization is considered a pre-requisite for the assessment of biological activity or determination of biological standards of the plant material. It provides the analytical characteristics which may prove to be useful in fixing the physicochemical standard for the Unani herbal drugs.

Sapistan (Cordia dichotoma) belongs to the family Ehretiaceae; its fruits and leaves are used in respiratory diseases such as asthma, cough, diphtheria, pneumonia, sore-throat, coryza. An effort has been made to carry out the physicochemical and phytochemical studies of plant. Physicochemical parameters as Extractive Values: Petroleum Ether (1.9%), Di-ethyl ether (0.85%), Chloroform (0.59%), Acetone (0.12%), Alcoholic (6.13%), Aqueous (10.44%); Solubility: Water (9.44 %) & Alcohol (1.16 %); Moisture contents (3.45 %), Total Ash values (7.188%), pH of 1% (6.76) & 10% solution (6.16) and loss on drying (5.3%). Phytochemical analysis: These revealed the presence of almost all the phyto-constituents in the test drug sample i.e. alkaloid, flavonoids, glycoside, carbohydrate, tannin, protein, amino acids, starch and resins.
