摘要: 为阐明酢浆草科植物杨桃(Averrhoa carambola)的化学成分,运用有机溶剂提取、萃取及多种色谱分离技术,从其叶中分离得到11个化合物。经光波谱分析,分别鉴定为苯基β-d-葡萄糖苷(1)、3,4,5-三甲氧基苯基β-d-葡萄糖苷(2)、苄基β-d-葡萄糖苷(3)、2-苯乙基芸香糖苷(4)、1-O-(3,5-二甲氧基-4-羟基苯甲酰)-β-d-葡萄糖(5)、5-羟基麦芽酚(6)、麦芽酚苷(7)、麦芽酚3-O-[6-O-(3-羟基-3-甲基-5-丁基戊二酰)]-β-d-葡萄糖苷(8)、乙基β-d-呋喃果糖苷(9)、丁基β-d-呋喃果糖苷(10)和鲨烯(11)。化合物8是1个新的人工产物,除化合物2和3外均为首次从杨桃属植物中得到。部分化合物与杨桃叶的抗炎、抗氧化和抗肿瘤作用相关。 |

Abstract: To clarify the chemical constituents in the leaves of Averrhoa carambola (Oxalidaceae), eleven compounds were isolated by means of organic solvent extraction and fractionation as well as diverse chromato-graphic separation techniques. On the basis of spectroscopic data, their structures were identified as phenyl β-d-glucoside (1), 3,4,5-trimethoxyphenyl β-d-glucoside (2), benzyl β-d-glucoside (3), 2-phenethyl rutinoside (4), 1-O-(3,5-dimethoxy-4-hydroxybenzoyl)-β-d-glucose (5), 5-hydroxymaltol (6), maltol β-d-glucoside (7), maltol 3-O-[6-O-(3-hydroxy-3-methyl-5-butylglutaroyl)]-β-d-glucoside (8), ethyl β-d-fructofuranoside (9), butyl β-d-fructofuranoside (10), and squalene (11), respectively. Compound 8 was a new artifact, and the others excluding 2 and 3 were obtained from the genus Averrhoa for the first time. Some compounds were related to the anti-inflammatory, antioxidant, and anti-tumor effects of the leaves. |
