Effect of Different Extraction Methods on the Chemical Constituents of Essential Oils from FOLIUM ARTEMISIAE ARGYI
摘要
Abstract
[Objective] To study the effect of different extraction methods on the chemical constituents of essential oils from FOLIUM ARTEMISI-AE ARGYI. [Method] The essential oils were first extracted from FOLIUM ARTEMISIAE ARGYI by steam distillation and SFE-CO2, and then qualitatively identified by GC-MS. Next, the relative content of each component was calculated by normalization method. [ Result ] There were significant differences in the chemical constituents of essential oils that were extracted from FOLIUM ARTEMISIAE ARGYI by different methods like steam distillation and SFE-CO2. The essential oils extracted by SFE-CO2 mainly contained 1,2-benzenedicarboxylic acid-2-ethylhexyl mono ester (17.81%) and l,2,3,4,4a,5,6,8a-octahydro-7-methyl-4-methylene-l-(l-methylethyl)-( la. Alpha. ,4a. Alpha. ,8a. Alpha. )-naphthalene (11.13%), while that extracted by steam distillation mainly contained 4,6,6-trimethyl-[ lS-( la,2β,5a) ]-bicyclo [3. 1. 1 ] hept-3-en-2-ol (22.05%), 4-methyl-l-(l-methylethyl)-[lS-(l. Alpha. , 4. Beta. ,5. Alpha. ) ]-bicyclo[3. 1.0]hexan-3-one (10.69%) and caryophyllene oxide (10.62% ). [Conclusion] The essential oils extracted from FOLIUM ARTEMISIAE ARGYI by SFE-CO2 contained more chemical constituents, especially low-polarity substance. However, the chemical constituents of essential oils extracted by steam distillation focused on higher-polarity alcohols. It was difficult to extract low-polarity volatile components by steam distillation.关键词
