Luteolin and Kaempferol From Cassia Alata, Antimicrobial and Antioxidant Activity of Its Methanolic Extracts

Cassia alata also known as candle bush is a medicinally important plant. In the present investigation we are reporting the isolation and structure elucidation of two flavonoids kaempferol (1) and luteolin (2) isolated from methanolic extract of its beans through bioassay guided fractionation. The structure of isolated compounds were characterized by spectroscopic techniques such as EIMS, 1H-NMR and 13C-NMR. In this article we are also presenting the antibacterial, antifungal and antioxidant activity of the methanolic extract of its leaves (CA-L), stem (CA-S) and beans (CA-BN). All the extracts showed remarkable antibacterial and weak antioxidant activity whereas moderate antifungal activity was only found in stem (CA-S) and beans (CA-BN) extracts
