- 中文摘要:
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. - 英文摘要: --
