NEW GALLIC ACID GLYCOSIDES FROM MALLOWS PLICATUS

摘要

From the stem bark of Mallotus plicatus (Mull.Arg.) Airy Shaw, two new gallic acid glycosides, namely bergenin-8-O-α-L-rhamnoside (1) and seco-bergenin-8-O-α-L-rhamnoside (2) were isolated along with seven known compounds (3-9). The structures of the new isolates (1 and 2) were elucidated through analysis of their 1D- and 2D-NMR, and MS spectral properties, as well as chemical evidence. seco-Bergenin-8-O-α-L-rhamnoside (2) and protocatechuic acid (7) showed weak inhibitory activity against Herpes simplex virus, whereas the other compounds were devoid of such activity.
