Chemical constituents from the fruits of Sorbus pohuashanensis

Abstract

Abstract The present phytochemical study firstly reported isolation of the individual chemical constituents from Sorbus pohuashanensis . Total 18 compounds of seven types have been isolated. Five triterpenes and six other compounds identified are firstly reported from the genus Sorbus . Phenylmethanol α-L-arabinofuranosyl(1→6)-β-D-glucopyranoside is firstly reported from the family Rosaceae. The quite limited but simultaneous occurrence of (3 S ,5 S )-3-(β-D-glucopyranosyloxy)-5-hydroxyhexonic acid ethyl ester and parasorboside suggested the close genetic relationship between S. pohuashanensis and Sorbus aucuparia .
