A new flavone, berberisinol (1), has been isolated from the EtOAc fraction of the MeOH extract of Berberis baluchistanica, along with known compounds, palmatine (2), berberine (3), 8-oxoberberine (4), β-sitosterol (5), oleanolic acid (6), and gallic acid (7), isolated for the first time from this species. Spectroscopic techniques including two-dimensional NMR were used for structural elucidation. Berberisinol (1) showed significant antibacterial and antioxidant potential.
从俾路支小檗的 MeOH 提取物的 EtOAc 部分中分离出了一种新的黄酮--小檗苷醇(1),以及首次从该物种中分离出的已知化合物巴马汀(2)、小檗碱(3)、8-氧代小檗碱(4)、β-谷甾醇(5)、齐墩果酸(6)和没食子酸(7)。利用包括二维核磁共振在内的光谱技术进行了结构阐释。小檗苷醇(1)具有显著的抗菌和抗氧化潜力。
