摘要
Two new germacrane sesquiterpenes： 3,8,14-trihydroxy- 1 （10）E,4Z, 11 （13）-germacra- trien-12, 6-olide, 8-（2-methyl-4-hydroxyl-2E-butenoyl）, 3,14-diacetoxy （eupalinolide A, 1）, and 3,8,14-trihydroxy-1（10） E, 4E, 11（13）-germacratrien-12,6-olide, 8-2-methyl-4-hydroxyl-2E- butenoyl）, 3,14-diacetoxy （eupalinolide B, 2） were isolated from Eupatorium lindleyanum. Their structures were elucidated by means of ^1H and ^13C NMR spectroscopic analysis, including 2D NMR technique.
