Abstract Gnetum species have been traditionally consumed as food and used as folk medicine to treat various pathological conditions. Ten compounds including three simple phenolic compounds (1–3), five stilbenoids (4, 5, 8–10), and two C-glycosyl flavanones (6 and 7), were isolated from the stems of Gnetum macrostachyum Hook. f. The structures of these compounds were elucidated by the analysis of spectroscopy data and their comparison with the reported values. This is the first report of the isolation of compounds 1–4 and 6–9 from G. macrostachyum. Compounds 1–3, 6, and 7 have not been previously reported from the genus Gnetum. The C-glycosyl flavanones in G. macrostachyum can be used as chemotaxonomic markers.

来自 Gnetum macrostachyum（Gnetaceae）茎的黄酮类化合物、芪类化合物和酚类衍生物

摘要 Gnetum 物种传统上作为食物食用，并作为民间药物用于治疗各种病理状况。从 Gnetum macrostachyum Hook 的茎中分离出 10 种化合物，包括三种简单酚类化合物 (1–3)、五种芪类化合物 (4, 5, 8–10) 和两种 C-糖基黄烷酮 (6 和 7)。F。这些化合物的结构通过光谱数据分析及其与报告值的比较来阐明。这是从 G. macrostachyum 中分离化合物 1-4 和 6-9 的第一份报告。化合物 1-3、6 和 7 以前从未报道过 Gnetum 属。G. macrostachyum 中的 C-糖基黄烷酮可用作化学分类标记。
