藤黄化学成分的研究

Studies on the Chemical Constituents of Garcinia hanburyi Hook. f.

采用正相、反相硅胶柱色谱法和半制备型高效液相色谱法对藤黄树脂的化学成分进行了分离和纯化,获得了5个化合物,通过NMR谱鉴定其结构分别为2α-羟基-3β-乙酰氧基白桦酯酸(I),2-O-乙酰基-山楂酸(II),邻苯二甲酸二丁酯(III),邻苯二甲酸二异丁酯(IV),邻苯二甲酸-二-2-乙基己酯(V),化合物2～5为首次从该植物中分离.

Five compounds were isolated from the resin of Garcinia hanburyi Hook. f. by silica get, reversed-phase silica gel column chromatography and semi-preparative high performance liquid chromatography. The structures were identified as 2a-hydroxy-3/3-acetoxy-lup-20 （29） -en-28-oic acid （ I）, 2-O-acetylmaslinic acid （ II）, dibutyl phthalate （ III）, diisobutyl phthalate （IV） and bis （2-ethylhexyl） phthalate （V） by NMR spectroscopy. Compounds 2 - 5 were obtained from the plant for the first time.
