Eight new prenylated flavonoids, khonklonginols A−H (1−8), together with six known compounds including five flavonoids, lupinifolinol (9), dehydrolupinifolinol (10), flemichin D (11), eriosemaone A (12), and lupinifolin (13), and one lignan, yangambin (14), have been isolated from hexane and dichloromethane extracts of the roots of Eriosema chinense. The structures of 1−8 were elucidated by spectroscopic methods. The compounds were evaluated for cytotoxic activity against the small-cell lung (NCI-H187) and oral epidermal carcinoma (KB) human cell lines as well as for antimycobacterial activity against Mycobacterium tuberculosis H37Ra.
