Macroscopic Characters Colour: ruby-red Odour: odourless Taste: Astringent Size: 3-10 mm granules Shape: angular grains Extra Features Shape: Angular, glistening, transparent, breaking with vitreous fracture. Solubility: It is partly soluble in water (about plant in 80-90 per cent), completely soluble in alcohol (90 per cent).
Chemical Constituents Kino contains about 70-80 per cent of kinotannic acid, kino-red, k- pyrocatechin (catechol), in and Gallic acid. Kinotannic acid is glucosidal tannin , while kino-red is anhydride of kinoin . Kinoin is an insoluble phlobaphene and is produced by the action of oxidase enzyme. It is darker in colour than kinotannic acid. Crystalline principle santal , pterocarpin and homopterocarpin are also present in the wood. If the juice is boiled during drying, enzyme gets destroyed and thus, insolubilisation and darkening is prevented.
Identification When the solution of drug is treated with ferrous sulphate, green colour is produced. With alkali (like potassium hydroxide) violet colour is produced. With mineral acid, a precipitate is obtained. Standards of Quality Water soluble extractives: Not less than 18.75 per cent Alcohol insoluble extractives: Not more than 80.0 per cent
