Chemical Constituents from the Aerial Part of Rosa Transmorrisonensis

Abstract The aerial part of Rosa transmorrisonensis Hayata contains chemical constituents of long‐chain alkanes, linolcnic acid, squalenc, catechin, sitosterol, sitosteryl‐)β ‐D ‐glucoside, 3,4,5‐trimethoxyphenyl‐(β ‐D‐ glucoside, 9‐glucosyl‐4,7 E ‐megastigmadien‐3‐one, oleanolic acid and eight ursolic acid derivatives. Among them, the new compound 14a was determined to be 2,3,4,6‐tetraacetyl‐(19α‐hydroxy‐2α,3α,24‐triacetoxyurs‐12‐en‐28‐oyl)‐β‐D‐glucopyranoside by spectral methods.
