To investigate the sesquiterpene lactones of the aerial parts of Inula helianthus-aquatica.
Compounds were isolated and purified by silica gel, Sephadex LH-20 and preparative HPLC. On the basis of physicochemical properties and spectroscopic data, their structures were identified.
Seven sesquiterpene lactones and four other compounds were obtained and identified as 2-desoxy-4-epi-pulchellin (1), 6-acetoxy-4-hydroxy-1, 10H-pseudoguaia-11 (13)-en-12,8-olide (2), 4-acetoxy-6-hydroxy-1, 10H-pseudoguaia-11(13)-en-12,8-olide (3), 8-epi-inuviscolide (4), 2,3,11,13-tetrahydroaromaticin (5), 11,13-dihydro-ergolide (6), 4-epipulchellin-2-O-acetate (7), 7-epiloliolide (8), loliolide (9), beta-sitosterol (10) and daucosterol (11).
All the compounds were isolated from this plant for the first time.
研究水朝阳旋覆花地上部分的倍半萜内酯。
采用硅胶柱色谱、葡聚糖凝胶LH-20柱色谱和制备型高效液相色谱法对化合物进行分离纯化。根据其理化性质和光谱数据鉴定其结构。
得到7个倍半萜内酯和4个其他化合物,分别鉴定为2-脱氧-4-表普氏千里光碱(1)、6-乙酰氧基-4-羟基-1,10H-伪愈创木-11(13)-烯-12,8-内酯(2)、4-乙酰氧基-6-羟基-1,10H-伪愈创木-11(13)-烯-12,8-内酯(3)、8-表异土木香内酯(4)、2,3,11,13-四氢芳香苦内酯(5)、11,13-二氢麦角甾内酯(6)、4-表普氏千里光碱-2-O-乙酸酯(7)、7-表裂环马钱子苷(8)、裂环马钱子苷(9)、β-谷甾醇(10)和胡萝卜苷(11)。
所有化合物均为首次从该植物中分离得到。
