目的对圆滑番荔枝种子氯仿部分的化学成分进行研究。方法运用正反相硅胶、Sephadex LH-20凝胶及制备高效液相等色谱技术进行分离纯化,并根据理化性质和波谱数据鉴定化合物的结构。结果分离得到13个化合物,分别鉴定为去乙酰紫玉盘素(1)、去乙酰异紫玉盘素(2)、泡泡树新素(3)、泡番荔枝辛(4)、毛曲番荔枝素(5)、4-desoxycherimolin-2(6)、atemotetrolin(7)、毛叶番荔枝素-2(8)、刺果番荔枝素B(9)、glabrin A(10)、邻苯二甲酸二丁酯(11)、番荔枝五醇C(12)、蔗糖(13)。结论其中化合物7和12为首次从该植物中分离得到,化合物11和13为首次从该属植物中分离得到。 Aim To study the chemical constituents of the seeds of smooth sugar litchi seeds. Methods The compounds were separated and purified by using silica gel, Sephadex LH-20 gel and preparative high performance liquid chromatography (HPLC). The structures of the compounds were identified by physicochemical properties and spectral data. Results Thirteen compounds were isolated and identified as deacetyl violet (1), deisoyl violet (2), dendrimerin (3), bubble apple (5), 4-desoxycherimolin-2 (6), atemotetrolin (7), triamcinolone 2 (8), punctaton B (9), glabrin A Dibutyl dicarboxylate (11), Annona C (12), sucrose (13). Conclusion Compounds 7 and 12 were isolated from this plant for the first time. Compounds 11 and 13 were isolated from this genus for the first time.
