Three new flavonol galloylglycosides from leaves of Acacia confusa.

摘要: Myricetin 3-O-(2‘ ‘-O-galloyl)-α-rhamnopyranoside 7-methyl ether (1), myricetin 3-O-(3‘ ‘-O-galloyl)-α-rhamnopyranoside (2), and 3-O-(2‘ ‘,3‘ ‘-di-O-galloyl)-α-rhamnopyranoside (3), three new flavonol galloylglycosides, were isolated from leaves of Acacia confusa sampled Chaoushi in the north Taiwan. Their structures established by analysis spectroscopic data, compounds evaluated for anti-hatch activity against brine shrimp.
