Chemical constituents of Biophytum sensitivum

Abstract

Two biflavones, cupressuflavone (1) and amentoflavone (2), three flavonoids, luteolin 7-methyl ether (3), isoorientin (4) and 3'-methoxyluteolin 7-O-glucoside (5), as well as two acids, 4-caffeoylquinic acid (6) and 5-caffeoylquinic acid (7) were isolated from the aerial parts of Biophytum sensitivum. Their structures were established on the basis of spectroscopic data.
