摘要:

目的分析比较不同水蒸气蒸馏法所得莲子心的挥发油成分。方法分别采用水蒸气蒸馏装置(SDA)和挥发油测定装置(EODA)的水蒸气蒸馏法提取莲子心挥发油，GC-MS分离鉴定挥发油成分，峰面积归一化法计算百分含量。结果采用SDA法，鉴定出29种成分，占挥发油总量91.56%，主要成分为棕榈酸(28.96%)、9,17-十八碳二烯醛(19.99%)和亚油酸(11.94%)等；采用EODA法，鉴定出18种成分, 占挥发油总量77.96%，主要成分为棕榈酸(18.98%)、肉桂酸龙脑酯(12.58%)、2-甲氧基-4-乙烯苯酚(8.25%)等。结论两种水蒸气蒸馏法所得挥发油成分存在较大差异，且SDA较EODA更适合于提取挥发油。

Abstract:

OBJECTIVE To compare chemical constituents of the essential oil from plumula nelumbinis by different stream distillation methods. METHODS The essential oil was extracted by stream distillation method of stream distillation apparatus (SDA) and essential oil determination apparatus (EODA). The constituents were separated and identified by GC-MS, the amounds of the constituents from the essential oil were determined by area normalization method. RESULTS There were 29 constituents from plumula nelumbinis by SDA, which accounted for 91.56% of total essential oil fraction. The major constituents are hexadecanoic acid (28.96%), 9,17-octadecadienal(19.99%) and 9,12-octadecadienoic acid(11.94%). There were 18 constituents from plumula nelumbinis by EODA, which accounted for 77.96% of total essential oil fraction. The major constituents are hexadecanoic acid (18.98%), propenoic acid borneol ester (12.58%), 2-methoxy-4-vinylphenol(8.25%). CONCLUSION There is a big difference in the composition of essential oil extracted by the two kinds of stream distillation methods. And SDA is more suitable than EODA for extracting essential oil.
