Two linear Annonaceous acetogenins, calamistrins H and I (1 and 2) were isolated from an ethanolic extract of the roots of Uvaria calamistrata Hance (Annonaceae) with silica gel column and preparative HPLC. Compounds 1 and 2 belong to a class of acetogenins without tetrahydrofuran (THF) ring on the chain. The structures of 1 and 2 were determined by spectroscopic analysis (NMR and MS) and chemical
用硅胶柱和制备型 HPLC 从 Uvaria calamistrata Hance (番荔枝科) 根的乙醇提取物中分离出两种线性番荔枝素,calamistrins H 和 I (1 和 2)。化合物 1 和 2 属于一类在链上没有四氢呋喃 (THF) 环的醋酸菌素。通过光谱分析(NMR 和 MS)和化学衍生物确定 1 和 2 的结构。
