摘要
目的:对胡椒科植物荜茇Piperlongum的化学成分进行研究。方法:荜茇用95%乙醇提取,依次用石油醚、氯仿、正丁醇萃取,对氯仿萃取部分采用各种柱色谱进行分离纯化,通过波谱数据分析(MS,1H-NMR,13C-NMR)进行结构鉴定。结果:从氯仿萃取部分分离鉴定了11个化合物,其中6个酰胺类生物碱,3个倍半萜,2个其他类化合物。分别鉴定为:类对香豆酰哌啶(coumaperine,1),N-5-(4-hydroxy-3-methoxyphenyl)-2E-pentenoyl piperidine(2),胡椒内酰胺A(piperolactam A,3),1-[1-oxo-5(3,4-methylenedioxyphenyl)-2E,4E-pentadienyl]-pirrolidine(4),1-[1-oxo-5(3,4-methylenedioxyphenyl)-2E-pentenyl]-pirroli-dine(5),1-[1-oxo-9(3,4-methylenedioxyphenyl)-2E,8E-nonadienyl]-pyrrolidine(6),姜黄酮[R-(-)-turmerone,7],octahydro-4-hydroy-3α-methyl-7-methylene-α-(1-methylethyl)-1H-indene-1-methanol(8),(+)-aphanamol I(9),二去甲氧基姜黄素(bisdeme-thoxycurcumin,10),去甲氧基姜黄素(demethoxycurcumin,11)。结论:化合物1-11均为首次从荜茇中分离得到。
Objective: To study the chemical constituents of Piper longum. Method: The whole plant of air-dried P. longum was extracted with 95 % EtOH. The EtOH extract was suspended in H2O and extracted with petroleum ether, CHCI3 and n-BuOH, successively. The compounds were isolated and purified by column chromatography from the CHCI3 fraction, and identified based on spectral analyses (MS, 1H-NMR, 13C-NMR). Result: Eleven compounds were isolated from P. longum, and were characterized as coumaperine ( 1 ), N-5- (4-hydroxy-3-methoxyphenyl) -2E-pentenoyl piperidine ( 2 ), piperolactam A (3), 1 -[ 1-oxo-5 ( 3,4-methylened- ioxyphenyl ) -2E,4E-pentadienyl ] -pirrolidine (4), 1 - [ 1 -oxo-5 ( 3,4-methylenedioxyphenyl) -2E-pentenyl ] -pirrolidine ( 5 ), 1 - [ 1 -oxo-9 ( 3,4-methylene dioxyphenyl ) -2E, 8E-nonadienyl ] -pyrrolidine ( 6 ), ( R ) - ( - ) -turmerone ( 7 ), octahydro-4-hydroy-3α-methyl-7- methylene-α- ( 1 -methylethyl) -1 H-indene-1 -methanol ( 8 ), ( + ) -aphanamol I (9), bisdemethoxycurcumin ( 10 ), demethoxycurcnmin (11). Conclusion: Compounds 1-11 were obtained from P. longum for the first time.
