MỘT SỐ HỢP CHẤT FLAVONOID GLYCOSIDE PHÂN LẬP TỪ LÁ CÂY KEO TAI TƯỢNG (ACACIA MANGIUM)

Tóm tắt

In this research, for the first time were six flavonoid glycosides isolated from the methanol extract of Acacia
mangium leaves by chromatography methods. Based on the data of MS and NMR spectral analysis
combined with the comparison with reported spectral data, structures of these compounds were elucidated
and they were respectively kaempferol-3-O-α-L-rhamnopyranosyl-(1-6)-O-[α-L-rhamnopyranosyl(1-2)]-Oβ-D-galactopyranoside, quercetin-3-O-α-L-rhamnopyranosyl-(1-6)-O-[α-L-rhamnopyranosyl(1-2)]-O-β-Dgalactopyranoside, afzelin, quercitrin, astragalin and isoquercetin.
