Phytochemical investigation on the stems of Trigonostemonheterophyllus led to the isolation of a new lariciresinol-based lignan glycoside, trigonoheteran (1), together with a known lignan glycoside, aviculin (2). Their structures were elucidated by spectroscopic methods including 1D and 2D NMR (HMQC, (1)H-(1)H COSY, HMBC, and NOESY).

对异叶三宝木茎进行植物化学研究，从中分离出一种新的基于落叶松脂醇的木脂素糖苷——三宝木异苷（1），以及一种已知的木脂素糖苷——杨梅苷（2）。通过包括一维和二维核磁共振（HMQC、氢-氢化学位移相关谱、异核多键相关谱和核欧沃豪斯效应谱）在内的光谱方法阐明了它们的结构。
