PMID 12575158

Abstract

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, beta-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.
