摘要：

Bioactivity-guided fractionation of the leaves of Selaginella willdenowii afforded three known biflavones, 4',7''-di-O-methylamentoflavone, isocryptomerin and 7''-O-methylrobustaflavone, that were significantly cytotoxic against a panel of human cancer cell lines. Non-cytotoxic isolates were also obtained, namely, amentoflavone, bilobetin, robustaflavone and 2'',3''-dihydroisocryptomerin, a new dihydrobiflavone. The structure for the new biflavonoid was unambiguously assigned by a combination of spectroscopic methods.
