Six new compounds, wikstronin A (1), wikstronin B (2), wikstresinol (3), acetylwikstresinol (4), bis-5',5'-(+)-matairesinol (5), bis-5,5'-(+)-matairesinol (6), together with 20 known compounds (7-26) were isolated from the CHCl extract of roots of Wikstroemia indica. Structures of compounds 1-6 were determined by extensive NMR and CD spectroscopic analysis. In vitro preferential cytotoxicity of all the isolates was evaluated against a PANC-1 human pancreatic cell line. Compounds 8 and 12 displayed mild preferential cytotoxicity in the nutrient-deprived medium (NDM) and without causing toxicity in normal nutrient-rich conditions.
从了哥王根的氯仿提取物中分离出6个新化合物，即了哥王素A（1）、了哥王素B（2）、了哥王树脂醇（3）、乙酰了哥王树脂醇（4）、双-5',5'-(+)-罗汉松脂酚（5）、双-5,5'-(+)-罗汉松脂酚（6），以及20个已知化合物（7 - 26）。通过广泛的核磁共振和圆二色光谱分析确定了化合物1 - 6的结构。评估了所有分离物对PANC - 1人胰腺癌细胞系的体外选择性细胞毒性。化合物8和12在营养缺乏培养基（NDM）中表现出轻度的选择性细胞毒性，且在正常营养丰富的条件下不产生毒性。
