dc.description.abstract | Two C,O-diglycosylated compounds, the anthrone picramnioside F, and the oxanthrone mayoside C, were isolated from the stem
bark of Picramnia teapensis, along with the previously reported anthraquinones, 1-O-b-d- and 8-O-b-d-glucopyranosyl emodin.
The compounds were separated by recycling-HPLC, and their structures were determined on the basis of spectroscopic analysis.
CD measurements were used to establish the absolute con®guration of the anthrone and oxanthrone. The antifungal activity of 1-
O-b-d- and 8-O-b-d-glucopyranosyl emodin against Leucoagaricus gongilophorus was shown to be similar to that of the lignan
sesamin. # 2000 Elsevier Science Ltd. All rights reserved. | es_ES |
