- W2381615811 abstract "Objective To isolate the chemical constituents and elucidate their structures from the flowers of Castanea mollissima Blume.Methods The compounds were isolated by column chromatography on silica gel,Sephadex LH-20 and so on,together with recrystallization methods.NMR spectral analysis and co-TLC were employed for the structural identification.Results Eleven compounds were obtained and elucidated as:2α,3β,23-trihydroxy-olean-12-en-28-acid(1),4-quinolinone-carboxylic-2-acid n-butyl ester(2),quercetin-3-O-β-D-galactopyranoside(3),kaempferol(4),quercetin(5),kaempferol-3-O-[6″-O-(E)-p-coumaroyl]-β-D-glucopyranoside(6),kaempferol-3-O-[2″,6″-di-O-(E)-p-coumaroyl]-β-D-glucopyranoside(7),gallic acid(8),protocatechuic acid(9),5-hydroxymethylfurfuraldehyde(10),quercetin-3-O-β-D-glucuronide 6″-methyl ester(11),respectively.Conclusions Compounds 1,2 and 11 are isolated from Castanea genus for the first time,and compound 3 is obtained from this plant for the first time." @default.
