PHARMACOGNOSTIC STUDIES OF DRUG SPERMADICTYON SUAVEOLENS ROXB.Abstract
The stem of Spermadictyon suaveolens Roxb. (Rubiaceae) was evaluated for its pharmacognostic characteristics. The stem was assessed for its macroscopic, organoleptic, microscopic and phytochemical characters. The macroscopic study revealed variation in color of the stem when fresh and dried. The macroscopic evaluation was studied with parameters viz. color, odor, shape, and surface in fresh and dry condition. Quantitative microscopical data of wood elements as well as stomatal index studied through standard procedures. Total ash, acid insoluble ash, percentage extractives and fluorescence analysis in addition tannin, flavonoid, alkaloid, saponin in the alcoholic extract of stem powder recorded during an investigation. The quantitative estimation of protein, carbohydrate and oil was carried out by different scientific denoted methods. In the propagation study through the stem, cutting showed maximum percent sprouting in the treatment IAA 100 ppm (65%) and maximum percent survival in the treatment IAA 100 ppm (60%) followed by IAA 50 ppm (42%). Antioxidant assay by using Superoxide Dismutase showed positive results 96.7% in dark condition.
