Two new dihydrostilbenes, stilbostemins H (1), I (2), and a new dihydrophenanthrene, stemanthrene E (3), were isolated and identified from the roots of Stemona sessilifolia, together with known stilbostemins B, D and G, and stemanthrenes A and C (4-8). Structures of new stilbenoids were established by 1D and 2D (1)H NMR and (13)C NMR spectroscopic analyses.
从直立百部的根部分离并鉴定出两种新的二氢茋类化合物，即茋百部素H（1）、I（2），以及一种新的二氢菲类化合物，百部蒽E（3），同时还分离出了已知的茋百部素B、D和G，以及百部蒽A和C（4 - 8）。通过一维和二维氢核磁共振（¹H NMR）以及碳核磁共振（¹³C NMR）光谱分析确定了新茋类化合物的结构。
