Abstract:
A new flavonoid, crotakanda (1), and seven known compounds including a flavonoid, four isoflavonoids, a pterocarpan and a cinnamaldehyde were isolated from the stems and roots of Crotalaria bracteata. Their structures were elucidated by a combination of spectroscopic methods. Compound 2 showed cytotoxicity against MCF-7 with an IC50 value of 79.90 μM whereas 2 and 4 exhibited cytotoxicity against the NCI-H187 cell line with IC50 values of 71.57 and 95.47 μM, respectively.
