Each method was evaluated in terms of qualitative and quantitative composition of the isolated essential oil by gas chromatography\/mass spectrometry (GC\/MS). The extract yields of essential oil were 0.16%, 2.18%, and 2.34%, respectively. A total of 82 compounds were identified by GC\/MS. The main components obtained by SDE were terpinen\u20104\u2010ol (20.98%), dipentene (11.67%), terpinene (9.24%), those by RE were palmitic acid (20.61%), 2\u2010chloroethyl linoleate (14.54%), tetracosane (12.26%), and \u03b1\u2010linolenic acid (11.24%), and those by USE were tetracosane (11.32%), heneicosane (11.06%), and palmitic acid (8.76%). Comparative analysis indicated that SDE was favorable for the extraction of monoterpene hydrocarbons, sesquiterpene hydrocarbons, alcohols, and carbonyl compounds, RE and USE had certain advantages in the extraction of aliphatic saturated hydrocarbons, organic acids, and esters. It is concluded that different extraction methods may lead to different yields of essential oils; the choice of appropriate method is very important to obtain more desired components with higher physiological activities.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Practical Application:\u2002<\/jats:bold>\n                    <jats:italic>C. aurantium<\/jats:italic>\n                    oils from different plant parts have great economic, medicinal, and nutritional values because of their wide\u2010spectrum biological activities.
