目的研究羊齿天门冬Asparagus filicinus根的化学成分。方法采用硅胶、Sephadex LH-20、ODS柱色谱及制备薄层色谱等技术进行分离纯化,通过波谱分析(MS、^1H-NMR、^13C—NMR)鉴定化合物结构。结果从羊齿天门冬根90%乙醇提取物的醋酸乙酯部分分离得到16个酚酸类化合物,分别鉴定为3'-methoxynyasin(1)、(+)-nyasol(2)、(-)-4’-O—methyl—nyasol(3)、iso—agatharesinol(4)、gobicusinA(5)、4-[5-(4-hydroxyphenoxy)-3-penten-1-ynyl]phenol(6)、1-methoxy-2-hydroxyl-4-[5-(4-hydroxyphenoxy)-3-penten-1-ynyl]phenol(7)、gobicusinB(8)、1-O-p-coumaroyl-3—O-feruloyl—glycerol(9)、1,3-di-O—feruloylglycerol(10)、丁香酸(11)、对羟基苯甲酸(12)、阿魏酸(13)、咖啡酸(14)、反式松柏醇(15)、香草酸(16)。结论除化合物2和12外,其他化合物均为首次从该植物中分离得到。
Objective To study the chemical constituents from the roots of Asparagus filicinus. Methods Silica gel, Sephadex LH-20, ODS column chromatography, and preparative TLC were used to isolate and purify the compounds. All the compounds were identified based on spectral analysis (including MS, ^1H-NMR, and ^13C-NMR). Results Sixteen phenolic compounds were isolated from 90% ethanol extract in the roots of A. filicinus and were characterized as 3'-methoxynyasin (1), (+)-nyasol (2), (-)-4'-0- methyl-nyasol (3), iso-agatharesinol (4), gobicusin A (5), 4-[5-(4-hydroxyphenoxy)-3-penten-l-ynyl] phenol (6), 1-methoxy-2- hydroxy-4-[5-(4-hydroxyphenoxy)-3-penten-l-ynyl] phenol (7), gohicusin B (8), 1-O-p-coumaroyl-3-O-feruloylglycerol (9), 1, 3-di-O-feruloylglycerol (10), syringic acid (11), 4-hydroxybenzoic acid (12), fumalic acid (13), caffeic acid (14), trans-coniferyl alcohol (15), and vanillic acid (16), respectively. Conclusion These phenolic compounds are isolated from A. filicinus for the first time except compounds 2 and 12.
