目的:研究薄叶红厚壳根的乙酸乙酯部位的化学成分。方法:运用各种色谱方法进行化学成分的分离纯化, 用理化方法和波谱数据解析其化学结构。结果:分离得到 11 个呫吨酮,结构分别为 1, 7-二羟基-3-甲氧基呫吨酮(1), 1, 5, 6-三羟基呫吨酮(2), 1, 3, 6-三羟基-5-甲氧基呫吨酮(3), 1, 3, 7-三羟基呫吨酮(4), 1-羟基-6, 7-二甲氧基呫吨酮(5), 3, 5-二羟基呫吨酮(6), 4-羟基-3-甲氧基呫吨酮(7), 1, 2-二甲氧基呫吨酮(8), 1, 3, 5-三羟基呫吨酮(9), pyranojacareubin(10), 1, 4, 5-三羟基呫吨酮(11)。结论:所有的化合物均为首次从该植物中分离得到, 其中 1, 3-7, 9 为首次从该属植物中分离得到。
Objective: To study the chemical constituents of the ethyl acetate fraction of the thin-shelled. Methods: The chemical constituents were isolated and purified by various chromatographic methods. Their chemical structures were elucidated by physical and chemical methods and spectral data. Results: 11 xanthones were isolated and their structures were 1, 7-dihydroxy-3-methoxyxanthenone (1), 1,5,6-trihydroxyxanthone (2), 1,3 (3), 1,3,7-trihydroxyxanthone (4), 1-hydroxy-6,7-dimethoxyxanthone (5 ), 3,5-dihydroxyxanthone (6), 4-hydroxy-3-methoxyxanthone (7), 1,2-dimethoxyxanthone (8) 5-Trihydroxyxanthone (9), pyranojacareubin (10), 1,4,5-trihydroxyxanthone (11). Conclusion: All the compounds were isolated from this plant for the first time. Among them, 1, 3-7 and 9 were isolated from this genus for the first time.
