Abstract: The extract parts of Gaultheria yunnanensis seeds, which were extracted with petroleum ether, chloroform, ethyl acetate, butanol, and water from 75% ethanol extract, were investigated through pharmacological experiments. The ethyl acetate extract was the antiphlogistic part. Through the use of chromatographic technology, eight compounds were isolated from the antiphlogistic part. Their structures were identified by spectroscopic analyses, such as NMR, IR and MS, etc.. They were physcion (1), 6-ethyl-5-hydroxy-2,7-dimethoxy-1,4-naphthoquinone (2), myricetin (3), 1,4-dihydroxybenzene (4), vanillic acid (5), β-daucosterol (6), β-sitosterol (7) and succinic acid (8). All compounds were isolated from the plant seeds for the first time.

Key words: Gaultheria yunnanensis seeds, chemical constituent, structure identification
