天南星挥发性成分研究

Determination of Chemical Constituents of the Volatile Oil from Arisaema erubescens (Wall.) Schott

目的:研究天南星中的挥发性成分。方法:利用水蒸气蒸馏法提取天南星(Arisaema erubescens (Wall.) Schott)挥发油,用GC-MS进行测定,结合计算机检索技术对分离的化合物进行结构鉴定,应用色谱峰面积归一化法计算各成分的相对百分含量。结果:鉴定出52个化学成分,其中相对百分含量大于2%的分别确定为间位甲酚(m-Cresol)5.31%,芫妥醇(Linalool L)3.69%,2,2’-次甲基呋喃(Furan,2,2’-Methylenebis)2.8%,2-糠基-5-甲基呋喃(2-Furfuryl-5-Methylfuran)2.52%,苯乙烯(Styrene)2.48%,2-烯丙基呋喃(Furan,2-(2-propenyl))2.15%,2-呋喃甲醇乙酸酯(2-Furanmethanol,acetate)2.12%。结论:52个挥发性成分均为首次从该植物中得到。

To study the chemical constituents of the volatile oil from Arisaema erubescens（ Wall. ） Schott. Method： The chemical compositions of the volatile oil of the plants which were obtained by steam distillastion with hexane were analyzed by GC - MS. The constituents were identified by their mass spectra. The relative percentage of the oil constituents was calculated froth the GC peak areas. Result： Seventy five kinds of chemical constituents in Arisaema erubescens （ Wall. ） Schott were separated; of which fifty- two compounds representing 56.11% of the oil were characterized. Relative contents that were more than 2% were determined as m - Cresol 5.31 %, Linalool L 3.69%, Furan,2,2＇ - Methylenebis 2.8%, 2 - Furfuryl - 5 - Methylfuran 2.52%, Styrene 2.48 %, Furan, 2 - （ 2 - propenyl ） 2.15 %, 2 - Furanmethanol, acetate 2.12%. Conclusion： This paper reported, for the first time, the composition of volatile oils of Radix morindae officinalis by GC/MS.
