| 摘要: | 目的 分析石南藤活性部位的化学成分。方法制备石南藤甲醇提取物的石油醚萃取部位,采用半制备液相色谱等技术进行分离与纯化,然后通过核磁共振波谱等方法对分离的化合物进行结构鉴定。结果从石南藤甲醇提取物的石油醚萃取部位分离得到19个化合物,分别鉴定为3-乙酰氧基苯甲酸苄酯(1)、2-乙酰氧基苯甲酸苄酯(2)、2-甲氧基苯甲酸苄酯(3)、3-甲氧基苯甲酸苄酯(4)、4-羟基-3-甲氧基苯甲酸苄酯(5)、3-羟基苯甲酸苄酯(6)、苯甲酸苄酯(7)、ganschisandrine(8)、lancifolinA(9)、(7R,8R,3′R)-7-acetoxy-3′,4′-dimethoxy-3,4-methylenedioxy-6′-oxo-Δ1′,4′,8′-8.3′-lignan(10)、(7S,8R,3′S)-Δ8′-3′,6′-dihydro-3′-methoxy-3,4-methylenedioxy-6′-oxo-8.3′,7.O.4′-lignan(11)、(7R,8R,3′S)-Δ8′-3′,6′-dihydro-3′-methoxy-3,4-methylenedioxy-6′-oxo-8.3′,7.O.4′-lignan(12)、isodihydrofutoquinolA(13)、licarinA(14)、licarinB(15)、2(-2′,5′-dimethoxyphenyl)-3,4-dimethyl-5(-3″,4″-dimethoxyphenyl)-tetrahydrofuran(16)、galgravin(17)、毡毛美洲茶素(18)、piyuninA(19)。结论化合物1为新发现的苯甲酸苄酯类化合物,化合物3~5、8、9为首次从胡椒属植物中分离得到,化合物2、6、10~13、15~19为首次从石南藤中分离得到。 |
| ABSTRACT: | OBJECTIVE To analyze the chemical constituents of the active parts of Piper wallichii. METHODS The petroleum ether-extract fraction was prepared from the methanol extract of P. wallichii. Separation and purification were performed using semi-preparative high-performance liquid chromatography. The structures of the compounds were identified by nuclear magnetic resonance spectroscopy. RESULTS Nineteen compounds were isolated from the petroleum ether-extract fraction from the methanol extract of P. wallichii, identified as 3-acetoxybenzyl benzoate (1), 2-acetoxybenzyl benzoate (2), 2-methoxybenzyl benzoate (3), 3-methoxybenzyl benzoate (4), 4-hydroxy-3-methoxybenzyl benzoate (5), 3-hydroxybenzyl benzoate(6), benzyl benzoate (7), ganschisandrine (8), lancifolin A (9), (7R,8R,3′R)-7-acetoxy-3′,4′-dimethoxy-3,4-methylenedioxy-6′-oxo- Δ1′,4′,8′-8.3′-lignan (10), (7S,8R,3′S)-Δ8′-3′,6′-dihydro-3′-methoxy-3,4-methylenedioxy-6′-oxo-8.3′,7.O.4′-lignan (11), (7R, 8R,3′S)-Δ8′-3′,6′-dihydro-3′-methoxy-3,4-methylenedioxy-6′-oxo-8.3′,7.O.4′-lignan (12), isodihydrofutoquinol A (13), licarin A (14), licarin B (15), 2-(2′,5′-dimethoxyphenyl)-3,4- dimethyl-5-(3″,4″-dimethoxyphenyl)- tetrahydrofuran (16), galgravin (17), velutin (18), and piyunin A (19). CONCLUSIONS Compound 1 is a new benzyl benzoate compound. Compounds 3-5, 8 and 9 are isolated from the Piper genus for the first time, while compounds 2, 6, 10-13 and 15-19 are isolated from P. wallichii for the first time. |
