目的研究白蔹的化学成分。方法利用各种色谱法进行分离,根据理化性质和波谱数据鉴定结构。结果从白蔹的乙酸乙酯萃取液中分离得到8个已知成分,分别鉴定为没食子酸(1)、原儿茶酸(2)、龙胆酸(3)、白藜芦醇(4)、大黄素(5)、羽扇豆醇(6)、β-谷甾醇(7)、胡萝卜苷(8)。结论化合物2和3为从该植物中首次分离得到。 Objective To study the chemical composition of Angelica. Methods Separation was performed using various chromatographic methods and the structures were identified on the basis of physicochemical properties and spectral data. Results Eight known components were isolated from the ethyl acetate extract of Angelica patens, identified as gallic acid (1), protocatechuic acid (2), gentisic acid (3), and resveratrol (4). Emodin (5), lupeol (6), β-sitosterol (7), and carotenoid (8). Conclusion Compounds 2 and 3 were isolated from this plant for the first time.
