New iridoid glycosides from the twigs and leaves of Callicarpa formosana var. formosana.J Asian Nat Prod Res. 2010 Mar; 12(3):220-6.JA
Four new iridoid glycosides, 6-O-benzoylphlorigidoside B (1), 6-O-trans-cinnamoylphlorigidoside B (2), 6-O-trans-p-coumaroylshanzhiside methyl ester (3), and 4'-O-trans-p-coumaroylmussaenoside (4), were isolated from the EtOH extract of the twigs and leaves of Callicarpa formosana var. formosana. Their structures were elucidated by extensive spectroscopic analysis.
