摘要

目的: 鉴别柳叶润楠叶挥发油中化学成分并测定其相对含量。方法: 采用水蒸气蒸馏法提取柳叶润楠新鲜叶中挥发油。运用GC-MS分析挥发油中化学成分并测定其相对含量，GC-MS条件为HP-FFAP石英毛细管柱（0.25 mm×30 m，0.25 μm），起始温度40℃，以5℃·min-1升温速率升温至200℃维持5 min，以8℃·min-1升温速率升温至280℃维持至完成分析，载气为氦气（99.999%），柱流量1.0 mL·min-1，进样口温度250℃，分流比50∶1，EI电离源70 eV，离子源温度230℃，四极杆温度180℃，溶剂延迟2.5 min，扫描范围m/z 50~550。结果: 挥发油提取率1.05%，共得到68种化合物，鉴定出55种（占挥发油总质量的77.10%），其中烯类化合物26个，醇类化合物12个，相对质量分数较高的组分为（Z-橙花叔醇（12.62%）、匙桉醇（7.48%）、喇叭茶醇（5.38%）。结论: GC-MS可用于鉴别和测定挥发性成分含量，为柳叶润楠的开发利用提供实验依据。

Abstract

Objective: To identify chemical components in volatile oil from Machilus salicina Hance and determine their relative contents. Method: Volatile oil from fresh leaves of M. salicina Hance was extracted by hydrodistillation.GC-MS was adopted to analyze chemical constituents in volatile oil and determined their relative contents

mass spectrometric conditions were as follows:HP-FFAP quartz capillary column(0.25 mm×30 m

0.25 μm)

the starting temperature 40℃

heated to 200℃ with 5℃· min-1

maintained 5 min

then with 8℃· min-1 heated to 280℃ until completion of analysis

helium as the carrier gas(99.999% )

column flow rate 1.0 mL· min-1

inlet temperature 250℃

split ratio 50:1

EI ionization source 70 eV

ion source temperature 230℃

quadrupole temperature 180℃

solvent delayed 2.5 min

scan range of m/z 50-550. Result: Yield of volatile oil was 1.05%

68 kinds of compounds were obtained and 55 kinds of compounds(accounted for 77.10% of total mass of volatile oil) were identified

26 of them was olefinic compounds

12 of them was alcohol compounds

the concentration of (Z)-nerolidol

spoon eudesmol and ledol were 12.62%

7.48% and 5.38%

respectively. Conclusion: GC-MS could be used to identify and determine content of volatile components

this study could provide experimental basis for development and utilization of M. salicina Hance.
