Abstract A phytochemical investigation of Picrasma quassioides (D.Don) Benn led to the isolation of seventeen compounds including five coumarins (1–5), six lignans (6–11), two alkaloids (12–13), two phenolic compounds (14–15), one megastigman glycoside (16) and one phenylpropanoid (17). The structures of those compounds were determined by spectroscopy data of NMR spectra. All of the compounds were isolated from P. quassioides for the first time. In this study, in order to discuss the chemotaxonomic significance of those compounds from P. quassioides, network analysis was carried out to determine the chemotaxonomic relationships among the Simaroubaceae family and the other families. The result showed that the Simaroubaceae family and the Rutaceae family, together with the Asteraceae family have some chemotaxonomic relationships.

Picrasma quassioides (D.Don) Benn 的化学成分。及其化学分类学意义的网络分析

摘要 对 Picrasma quassioides (D.Don) Benn 的植物化学研究导致分离出 17 种化合物，包括五种香豆素 (1-5)、六种木脂素 (6-11)、两种生物碱 (12-13)、两种酚类化合物 (14 –15)、一种 megastigman 苷 (16) 和一种苯丙烷 (17)。这些化合物的结构由NMR光谱的光谱数据确定。所有化合物均为首次从P. quassioides中分离得到。在本研究中，为了讨论拟南芥中这些化合物的化学分类学意义，通过网络分析确定了苦木科与其他科之间的化学分类关系。结果表明，苦木科和芸香科以及菊科有一定的化学分类关系。
