摘要
首次研究了硕苞蔷薇(Rosa bracteata Wendl.var.bracteata)的化学成分。从果实中共分离出6个化合物,鉴定了其中4个,分别为5-羟甲基糠醛(5-hydroxymethyl furfural)、5-乙酰氧基糠醛(5-ace-toxymethyl furfural)、β-谷甾醇(sitosterol)、齐墩果酸(oleanolic acid),其中5-羟甲基糠醛和5-乙酰氧基糠醛为首次从Rosa属植物中分得;同时,分离出一个白色腊状物,经GC-MS联用鉴定,其主要组成为十九碳烯、二十二烷、三十一烷、三十六烷。
The chemical constituents of Rosa bracteata Wendl. var. bracteata were studied for the first time.Six compounds were isolated from the fruits of the plant, and four of them have been identified as 5-hydroxymethyl furfural,5-acetoxymethyl furfural,β-sitosterol,oleanolic acid. 5-hydroxymethy furfural and 5-acetoxymethyl furfural were obtained from genus Rosa L.for the first time. Otherwise, a white wax was obtained by silica gel column chromatography, from which four main constituents were identified as nonadecene,n-docosane,hentriacontane and hexatriacontane by GC-MS.
