From Morus alba leaves, the following 11 flavonoid-terpenoid compounds were extracted and isolated: 3, 4-dihydroxybenzoic acid, ellagic acid, gallic acid, Kaempferol 3-O-β-D-glucopyranoside, Quercetin 3-O-α-L-rhamnopyranoside, isofraxidin-7-O-β-D-glucopyranoside, (±) - 3, 5, 6, 7, 8, 4'-hexahydroxyflavane, Kaempferol-3, 7-O-αL-rhamnopyranoside, 7, 4'-dihydroxy-5, 3'-dimethoxyflavone, (S) - 5, 5', 7-trihydroxy-2', and 4'dimethoxy-6-methylflavanone.
Từ lá dâu tằm, đề tài đã chiết xuất, phân lập được các phân đoạn dịch chiết và 11 hợp chất nhóm flavonoid, terpenoid là: Acid 3,4 dihydroxybenzoic, Acid ellagic, Acid gallic, Kaempferol 3 - O-β-D-glucopyranosid, Quercetin 3 - Oα-L-rhamnopyranosid, isofraxidin-7 - O - β - D-glucopyranosid, (±) -3,5,6,7,8,4 - hexahydroxyflavan, Kaempferol-3, 7 - di-O-α-L-rhamnopyranosid, 7,4 - dihydroxy-5, 3 - dimethoxyflavon, (S)-5,5,7trihydroxy-2,4-dimethoxy-6-methylflavanon.
