previously reported the isolation of sesquiterpene lactones from an ethanolic extract of the epigeal part of Sauss~ea elegans Ledeb. [i]. When the benzene fractions obtained in the separation of the ethereal sum of the ethanolic extract were rechromatographed on type KSK silica gel [with the eluent hexane--ethyl acetate (12:1)], two crystalline substances were isolated: (I) -Cs2H520~, mp 239-241°C
我们之前曾报道过从秀丽隐杆线虫 (Sauss~ea elegans Ledeb) 的表皮部分的乙醇提取物中分离出倍半萜内酯。[一世]。当在乙醇提取物的醚类总和分离中获得的苯馏分在 KSK 型硅胶上进行再色谱分离时 [洗脱液为己烷--乙酸乙酯 (12:1)],分离出两种结晶物质:(I) -Cs2H520 ~, mp 239-241°C (乙醇); (II) -C29H5o0, mp 137139°C (丙酮)。
