摘要：

Four new compounds, stigmastanol-3 beta-p-glyceroxydihydrocoumaroate (1), stigmastanol-3 beta-p-butanoxydihydrocoumaroate (2), lanast-7,9(11)-dien-3 alpha,15 alpha-diol-3 alpha-D-glucofuranoside (3) and 1-phenyl-2-hydroxy-3,7-dimethyl-11-aldehydic-tetradecane-2-beta-D-glucopyranoside (4), along with several known compounds were isolated from the methanol extract of hulls of Oryza sativa. The new structures were established by one- and two-dimensional NMR and in combination with IR, EI/MS, FAB/MS and HR-FAB/ MS. Compound (3) strongly inhibited the growth of duckweed (Lemna paucicostata Hegelm 381), whilst compounds (2) and (4) exhibited weak inhibition. Copyright (c) 2005 John Wiley & Sons, Ltd.
