目的:研究山小橘的化学成分。方法:采用乙醇渗辘提取结合正反相色谱法进行分离纯化,根据波谱学方法,同时结合理化性质鉴定化合物的结构。结果:从山小橘中分离得到11个化合物,分别鉴定为:5,7,4’-三羟基-二氢黄酮醇(1)、香橙素(2)、反式-二氢槲皮素(3)、顺式-二氢槲皮素(4)、山柰素(5)、槲皮素(6)、5,7,4’-三羟基-二氢黄酮醇-3-O-α-L-吡喃鼠李糖苷(7)、槲皮素-3-O-α-L-呋喃阿拉伯糖苷(8)、槲皮素-3-O-α-L-吡喃鼠李糖苷(9)、5,7,3’,4’-四羟基黄酮-3-O-吡喃鼠李糖(1→6)吡喃葡萄糖苷(10)、5,7,3’-三羟基-4’-甲氧基黄酮-3-O-吡喃鼠李糖(1→6)吡喃葡萄糖苷(11)。结论:所有化合物均为首次从该植物中分离得到。
Objective: To study the chemical constituents Methods: The compounds were isolated and purified by ethanol permeable reel extraction combined with positive and negative phase chromatography. The structures of the compounds were identified by physicochemical properties according to spectroscopic methods. Results: Eleven compounds were isolated and identified as 5,7,4’-trihydroxyflavanone (1), orange (2), trans-dihydroquercetin (3), cis-dihydroquercetin (4), behenin (5), quercetin (6), 5,7,4’-trihydroxyflavanol-3-O- (7), quercetin -3-O-α-L-arabinofuranoside (8), quercetin -3-O-α-L-rhamnopyranoside ), 5,7,3 ’, 4’-tetrahydroxyflavone-3-O-rhamnopyranosyl (1 → 6) glucopyranoside (10), 5,7,3’-trihydroxy-4’ - Methoxyflavone-3-O-rhamnopyranosyl (1 → 6) glucopyranoside (11). Conclusion: All the compounds were isolated from this plant for the first time.
