摘要：
Two new diterpene glycosides, 8-0-beta-D-xylopyranosyl-ent-8beta-hydroxylabdan-15-oic acid [1) and 8-0-beta-D-glucopyranosyl-ent-85-hydroxylabdan-15-oic acid [2], were isolated from Heterothalamus alienus. Their structures were elucidated by nmr spectroscopy, and their absolute configurations were determined by tranformation of both natural products into methyl ent-8beta-hydroxylabdan-15-oate. The sugar residues were identified after acid hydrolyses of the two natural products.
