A new alkaloid, stemona-lactam S, and a known alkaloid, tuberostemospiroline, were isolated from the roots of Stemona tuberosa LOUR. (Stemonaceae). Their structures and absolute stereochemistry were established by X-ray crystallography and vibrational circular dichroism.
从百部科植物直立百部（Stemona tuberosa LOUR.）的根中分离出一种新生物碱——百部内酰胺S和一种已知生物碱——对叶百部螺碱。通过X射线晶体学和振动圆二色光谱确定了它们的结构和绝对立体化学。
