Physiochemical analysis and HPLC-PDA method for quantification of stigmasterol in Dipteracanthus patulus (Jacq.) Nees

Physiochemical analyses have shown the purity and quality of crude drug. Quantitative estimation by HPLC-PDA revealed the presence of good percentage of stigmasterol in D. patulus. This study has grasped the importance since stigmasterol possesses lipid peroxidation inhibitory action and anticancer activity. These features make this plant a promising candidate for the further studies on isolation and pharmacological studies of this compound from D. patulus.
