The purpose of this research was to compare the constituents of essential oil extracted from Hydrocotyle sibthorpioides Lam. and leaves of Zanthoxylum nitidum (Roxb.), respectively. First, thirty-four essential oil compounds from the extract of the Hydrocotyle sibthorpioides (Lam.) and twenty-four essential oil compounds from the extract of the leaves of Zanthoxylum nitidum (Roxb.) were identified, respectively. The constituents from the essential oil of both plants contained the same eight compounds: β-Elemene、β-Ionone、α-Humulene、β-Bisabolene、β-Caryophyllene、α-Selinene、 Caryophyllene oxide and Phytol. The essential oil was extracted from both plants by steam distillation, and the amount (V%) of the neutral essential oil collected was about 0.211% and 0.046%, respectively. |
