摘要
目的对国产肉桂Cinnamomumcassia的化学成分进行研究。方法采用正、反相硅胶柱色谱、凝胶柱色谱及半制备液相色谱等方法进行分离纯化,利用波谱分析结合理化性质鉴定化合物结构。结果从国产肉桂的醋酸乙酯提取物中分离得到15个化合物,分别鉴定为锡兰肉桂素(1)、脱水锡兰肉桂素(2)、脱水锡兰肉桂醇(3)、锡兰肉桂醇(4)、落叶脂素(5)、Evofolin B(6)、5′-甲氧基松脂醇(7)、(+)-丁香树脂素(8)、2-羟基肉桂酸(9)、1,10-seco.4ζ-hydroxy—muurolene-1,10-diketone(10)、(-)-表儿茶素(11)、山柰酚(12)、原花青素A2(13)、豆甾醇(14)、硬脂酸(15)。结论化合物5~7、10为首次从该种植物分离得到的木脂素成分,化合物1~4为首次从国产肉桂中分离得到的瑞诺烷类二萜成分。
Objective To study the chemical constituents from the barks of Cinnamomum cassia. Methods Silica gel, ODS, Sephadex LH-20 column chromatography, and semi-preparative HPLC were used to isolate the compounds. The structures of the compounds were identified on the basis of their physicochemical properties, spectroscopic data, and with the literature. Results Fifteen compounds were isolated from the barks of C. cassia growing in China, including cinnzeylanine (1), anhydrocinnzeylanine (2), anhydrocinnzeylanol (3), cinnzeylanol (4), (-)-lariciresinol (5), evofolin B (6), 5'-medioresinol (7), (+)-syringaresinol (8), 2-hydroxyl cinnamie acid (9), 1, 10-seco-4ζ-hydroxy-muurol-ene-1, 10-diketone (10), (-)-epicatechin (11), kaempferol (12), proanthocyanidin A2 (13), stigmasterol (14), and stearic acid (15). Conclusion Compounds 5-7 and 10 are lignans isolated from the plant for the first time, and compounds 14 are ryanodanediterpenes isolated from the barks of C cassia growing in China for the first time.
