Chemical Constituents and Tyrosinase Inhibitory Activity of Ethyl Acetate Extract of the Leaves of Morus alba L. from VietnamBy Loi Vu Duc, Tung Bui Thanh, Huong Le Thi Thu
Abstract: AbstractFour compounds (DB1–4) were isolated from the Mulberry leaves (Morus alba L.) collected in Thai Nguyen province by chromatographic methods. These compounds were identified as: Kaempferol-3-O-β-D-glucopyranoside (DB1), quercetin 3-O-α-L-rhamnopyranoside (DB2), isofraxidin-7-O-β -D-glucopyranoside (DB3), and (±) -3, 5, 6, 7, 8, 4’-hexahydroxyflavane (DB4). Their structures were elucidated by spectroscopic methods, including mass spectrometry (MS) and nuclear magnetic resonance (NMR). Compound DB4 was isolated from Mulberry leaves for the first time. Compound …

Chemical Constituents and Tyrosinase Inhibitory Activity of Aqueous Fraction of the Leaves of Morus alba L. from VietnamBy Loi Vu Duc
Abstract: The mulberry has been widely cultivated to feed silkworms. The leaves of mulberry have been used in traditional medicine as an analgesic, antitussive, cathartic, diuretic. In this study we have isolated three compounds (LC1-3) by chromatographic methods from the Mulberry leaves (Morus alba L.) collected in Thai Nguyen province, Vietnam. These compounds were identified as: Kaempferol-3,7-di-O-α-L-rhamnopyranoside (LC1), 7,4’-dihydroxy-5,3’-dimethoxyflavone (LC2), (S)-5,5’,7-trihydroxy-2’,4’-dimethoxy-6-methylflavanone (LC3). Their structures were elucidated by spectroscopic methods, including MS …
