Diversity of Chemical Constituents from Saxifraga Montana H.

A thorough phytochemical investigation of the whole plant of Saxifraga montana H. afforded a new glucoside, methyl 6″‐O‐(E)‐p‐hydroxycinnamoxyl‐glucosyringate (1), and seventeen known natural products, 3‐methyl‐6‐methoxy‐3,4‐dihydroisocoumarin‐8‐O‐β‐D‐glucospyranoside (2), gallic acid (3), glucosyringic acid (4), daphnoretin (5), chamaejasmoside (6), myricetin (7), quercetin (8), quercetin‐3‐O‐β‐D‐galactopyranoside (9), quercetin‐3‐O‐α‐L‐arabinoside (10), quercetin‐3‐O‐β‐D‐glucospyranoside (11), rutin (12), quercetin‐3‐O‐β‐D‐glucopyranosyl (6‐1) glucopyranoside (13), ursolic acid (14), 5,28‐stigmastadien‐3β‐ol (15), β‐sitosterol (16), β‐daucosterin (17), 6′‐palmitoxyl‐β‐daucosterin (18). On the basis of various spectroscopic methods, especially intensive 2D‐NMR (COSY, HMQC and HMBC), FAB‐MS and HR‐ESI‐MS techniques, their structures were elucidated.
