Abstract Phytochemical investigation on the stem bark of Goniothalamus tapis Miq. led to the isolation of seven known styryl-lactones, 3-acetyl-isoaltholactone (1), goniothalamin (2), isoaltholactone (3), cheliensisin A (4), 7-epi-goniofufurone (5), goniopypyrone (6), garvensintriol (7), and two steroids, stigmasterol (8) and β-sitosterol (9). The structures of all the compounds were elucidated based on the analysis of spectroscopic data and comparison with reported literature. The chemotaxonomic significance of all these compounds were summarized. Among all the styryl-lactones, compound 1 was isolated naturally from plant for the first time while compounds 4, 5 and 7 have not been previously reported in Goniothalamus tapis Miq. Compound 2 was the first styryl-lactone isolated from many species of Goniothalamus including other families such as Cucurbitaceae, Lauraceae, Stemonaceae and Apocynaceae). Compounds 3 and 6 were found in ten species of Goniothalamus where the latter were also found in other genus (Polyalthia Blume).

Goniothalamus Tapis Miq 茎皮的植物化学成分

摘要 Goniothalamus Tapis Miq 茎皮的植物化学研究。导致分离出七种已知的苯乙烯基-内酯、3-乙酰基-异戊内酯 (1)、goniothalamin (2)、isoaltholactone (3)、cheliensisin A (4)、7-epi-goniofufurone (5)、goniopypyrone (6)、 garvensintriol (7) 和两种类固醇，豆甾醇 (8) 和 β-谷甾醇 (9)。所有化合物的结构都是基于光谱数据的分析和与报道的文献比较来阐明的。总结了所有这些化合物的化学分类学意义。在所有的苯乙烯基-内酯中，化合物 1 首次从植物中自然分离出来，而化合物 4、5 和 7 以前从未在 Goniothalamus Tapis Miq 中报道过。化合物 2 是从包括葫芦科、樟科、百合科和夹竹桃科等其他科的许多种属中分离得到的第一个苯乙烯基-内酯。化合物 3 和 6 在 10 种 Goniothalamus 中被发现，后者也在其他属 (Polyalthia Blume) 中发现。
