Two new 2-C-beta-D-glucopyranosyl benzoic acid derivatives named mallonanosides A
(1) and B (2) were isolated from the methanolic extract of the leaves of Mallotus
nanus along with five known flavonoids, kaempferin (3), juglanin (4), quercitrin 
(5), myricitrin (6), and rhoifolin (7). Their structures were established on the 
basis of spectral and chemical evidence. Their antioxidant activities were shown 
to depend on the number of hydroxyl groups, and the location and species of sugar
moiety.
