目的:研究养心草宁心安神活性部位的化学成分。方法:采用多种柱色谱方法进行分离,应用波谱法鉴定结构。结果:从养心草醇提取物的乙酸乙酯和正丁醇萃取部位分离得到9个化合物。经理化性质和波谱方法鉴定为:①没食子酸,②齐墩果酸,③异鼠李素,④山奈酚,⑤对羟基苯甲酸,⑥槲皮素,⑦β-胡萝卜苷,⑧槲皮苷,⑨2-乙酰萘。结论:化合物异鼠李素、对羟基苯甲酸、2-乙酰萘为首次从该植物中分离到。 Objective: To study the chemical constituents of the active site of Yang Xin Cao Ning Anshen. Methods: Various column chromatographic methods were used for separation, and the structure was identified by spectroscopy. Results: Nine compounds were isolated from the ethyl acetate extract and the n-butanol extract of the extract of Centella asiatica. The physicochemical properties and spectroscopic methods were identified as follows: ① gallic acid, ② oleanolic acid, ③ isorhamnetin, ④ kaempferol, ⑤ para-hydroxybenzoic acid, ⑥ quercetin, ⑦ β-daucosterol, ⑧ quercitrin, ⑨ 2-acetyl naphthalene. Conclusion: The compounds isorhamnetin, p-hydroxybenzoic acid and 2-acetyl-naphthalene were isolated from this plant for the first time.
