Four stilbene derivatives, gnemonols K and L (resveratrol trimers), M (isorhapontigenin dimer), and gnemonoside K (glucoside of resveratrol trimer) together with eleven known stilbenoids and a lignan were isolated from the acetone, methanol and 70% methanol soluble parts of the root of Gnetum gnemon (Gnetaceae). The structures of the isolates were determined by spectral analysis. The antioxidant activity of the stilbenoids on lipid peroxide inhibition and super oxide scavenging activity were also investigated.
从买麻藤（买麻藤科）根的丙酮、甲醇及70%甲醇可溶部分中分离得到4种芪衍生物，即格木醇K和L（白藜芦醇三聚体）、M（异落花生苷元二聚体）和格木苷K（白藜芦醇三聚体的糖苷），以及11种已知的芪类化合物和1种木脂素。通过光谱分析确定了分离物的结构。还研究了芪类化合物对脂质过氧化物抑制和超氧化物清除活性的抗氧化活性。
