Phytochemical investigation of the stems of Kadsura heteroclita led to isolation of 16 compounds, including the triterpenoid named longipedlactone J (2), and two dibenzocyclooctadiene type lignans named heteroclitin I and J (3, 4). Compounds 8-10, 14, and 15 were weakly active as anti-HIV agents, whereas compounds 6 and 12 exhibited moderate anti-HIV activity with EC50 values of 1.6 microg/mL, and 1.4 microg/mL, therapeutic index (TI) values of 52.9, and 65.9, respectively. Their structures were established by spectroscopic methods, including application of 2D NMR techniques and CD spectra.
对异型南五味子茎进行植物化学研究，分离出16种化合物，包括三萜类化合物长梗南五味子内酯J（2），以及两种二苯并环辛二烯型木脂素异型南五味子素I和J（3,4）。化合物8 - 10、14和15作为抗HIV药物活性较弱，而化合物6和12表现出中等抗HIV活性，其半数有效浓度（EC50）值分别为1.6微克/毫升和1.4微克/毫升，治疗指数（TI）值分别为52.9和65.9。通过光谱方法，包括二维核磁共振（2D NMR）技术和圆二色光谱（CD）确定了它们的结构。
