目的研究猫爪草中的化学成分。方法用各种色谱方法分离猫爪草中的化学成分,用理化常数和波谱技术对分离的化合物进行结构鉴定。结果从猫爪草块根中分离得到8个化合物,结构分别确定为棕榈酸(1),β-谷甾醇(2),γ-酮-δ-戊内酯(3),尿苷(4),5-羟甲基-糠醛(5),3,4-二羟基苯醛(6),呋喃果糖(7),β-谷甾醇-β-D-葡萄糖苷(8)。结论化合物(4),(5),(6)为从该植物中首次分离得到。 Objective To study the chemical constituents in Cat’s claw grass. Methods The chemical constituents in Cat’s claw grass were separated by various chromatographic methods. The structures of the isolated compounds were identified by physicochemical constants and spectroscopic techniques. Results Eight compounds were isolated from the roots of Cat’s claw, and their structures were identified as palmitic acid (1), β-sitosterol (2), γ-keto-δ-valerolactone (3), uridine (4), 5-Hydroxymethyl-furfural (5), 3,4-dihydroxybenzaldehyde (6), fructofuranose (7), β-sitosterol-β-D-glucoside (8). Conclusion Compounds (4), (5), (6) were isolated from this plant for the first time.
