Dr. M. Anitha*
ABSTRACT
Steriospermum suaveolens DC (Bignoniaceae) commonly known as “Padari”. It is widely available in India. Traditionally it is used as analgesic, wound healing, anti dyspeptic, astringent and liver stimulant. The aim of the present study is to evaluate physicochemical parameters of bark of Steriospermum suaveolens which includes physico-chemical constant, phytochemical screening and fluorescence analysis. The total ash content of the bark powder is 95% and the extractive value of water is more than other solvents. The bark powder shows the characteristics fluorescent colour when treated with 50% H2SO4, Alcoholic NaOH and picric acid under UV light. The methanol extracts shows the presence of catechin, flavanoid, phenol, quinine, saponin, steroid, terpenoid, sugar and glycoside. These findings will be useful towards establishing pharmacognostic standards on identification, purity, quality and classification of the plant, which is important in plant drug research.
Keywords: Pharmacognosy, physico-chemical, phytochemical, Steriospermum suaveolens.
