ABSTRACT
Six new iridoid glycosides were isolated from the ethyl acetate fraction of the whole plants of Hedyotis diffusa Willd. They were identified as E-6-O-p-methoxycinnamoyl-10-O-acetyl scandoside acid methyl ester (1), Z-6-O-p-methoxycinnamoyl-10-O-acetyl scandoside acid methyl ester (2), E-6-O-caffeoyl scandoside methyl ester (3), E-6-O-p-coumaroyl-6'-O-acetyl scandoside methyl ester (4), Z-6-O-p-coumaroyl-6'-O-acetyl scandoside methyl ester (5), and E-6-O-p-coumaroyl-4'-O-acetyl scandoside methyl ester (6). The structures of them were elucidated based on unambiguous spectroscopic data (UV, IR, HRESIMS, and NMR). They were screened for anti-inflammatory effect, antioxidant effect, antitumor effect, and neuroprotective effect and did not show potent activities.
