  By Loi Vu Duc, Xuan Bui Thi, Ngoc Tran Minh

  Abstract: From the aqueous extract of the leaves of Sanchezia nobilis Hook.f. collected in Nam Dinh province by chromatographic methods. Their chemical structures were elucidated by the measurements of melting temperature, rotation angle, mass spectrometry (MS), nuclear magnetic resonance (NMR) and compared with previously published data. These were identified as: 4',5,7-trihydroxy-3',5'-dimethoxyflavone (NX1), kaempferol-3-O-α-L-arabinofuranoside (NX2), kaempferol-3-O-β-D-glucopyranoside (NX3). These all compounds were isolated from the leaves of Sanchezia nobilis for the first time. …
