• 中文摘要： 從羊角藤果實的萃取液中，分離出二個新的類三菇化合物(1)，(3)及四個已知的化合物。經過物理及化學的方法證明的結果，這二個新的化合物，分別為cycloartenyl cinnamate（1）和D-friedoolean-llα,12-epoxy-14-en-3β-y1 cinnamate（3）。本研究亦同時完成了抗菌活性試驗。
• 英文摘要： Two new triterpenoids (1 and 3) were isolated from the fruits of Gymnema altemifolium (Lour.)Merr. (Asclepiadaceae) together with 24-methylene cycloartanyl cinnamate, βamyrin cinnamate, βamyrinacetate and methyl-α-D-galactopyranoside. The structures of 1 and 3 were shown to be cycloartenyl cin-namate and D-friedoolean-llα, 12α-epoxy-l4-en-3β-yl cinnamate, respectively, based on the physical andchemical data. Besides, the antimicrobial activities of cycloartenyl cinnamate, D-friedoolean-llα,12α-epoxy-14-en-3β-yl cinnamate, β-amyrin cinnamate and two related compounds, cycloartenol and D-friedours-llα,12α-epoxy-14-en-3β-ol were examined by using the agar-dilution-plate method.
