Physicochemical and Phytochemical Examination of Medicinal Plants Used in Indigenous System of Medicine

Abstract

The present paper deals with the physicochemical and phytochemical examination of seventy-six medicinal plants belonging to thirty-six dicot and six monocot families. These are used in indigenous system of medicine as well as local inhabitants either as single drugs or in combination, for the cure of various ailments. In physicochemical study, the parameters such as moisture content, pH (1% aqueous), total ash, acid insoluble ash, water-soluble extractive and alcohol soluble extractive were carried out. The preliminary phytochemical study was done for the detection of secondary metabolites such as alkaloid, flavonoid, glycoside, phenol, saponin, resin, steroid and tannin. The preliminary phytochemical study revealed the presence of alkaloid and saponin in 68.4%; flavonoid in 44.7%; glycoside, phenol and steroid in 72.37%; resin in 60.5% and tannin in 71% of selected medicinal plants.
