Abstract

Chloroxylon swietenia Linn. belongs to the family Rutaceae / Chloroxylaceae, is a medicinal and aromatic tree of dry deciduous forests. It is popularly known as yellow wood, East Indian satin wood and Ceylon satin wood. The leaves have credited for its effectiveness in the treatment of common cough and cold, it is also used as an astringent. Its pharmacognostic data for authentication of the crude drug is not available, hence, in the present study, macroscopical, microscopical, and preliminary phytochemical investigations of leaves is undertaken. Powder microscopy revealed that phloem fiber, covering trichome, mesophyll with oil glands. T.S of leaf shows cuticle, collenchymatous cells, oil glands, trichomes, xylem and epidermal cells. The qualitative chemical tests of petroleum ether, chloroform, acetone, ethanol and water extracts of leaves revealed the presence of carbohydrates, alkaloids, glycosides, flavonoids, phenolic compounds and tannins.

Keywords: Chloroxylon swietenia, macroscopic, microscopy, preliminary phytochemical analysis.
