Chemical constituents from the fruits of Sorbus pohuashanensis

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 (3S,5S)-3-(β-D-glucopyranosyloxy)-5-hydroxyhexonic acid ethyl ester and parasorboside suggested the close genetic relationship between S. pohuashanensis and Sorbus aucuparia.
