Oils,Essential
《英文msh词典》Oils,Essential [同义词] Oils,Essential [主题词] Oils,Volatile [中文释义] 油类,芳香 [英文释义] Oils which evaporate readily. The volatile oils occur in aromatic plants,to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleopten (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant,as its perfume or scent,and not to its indispensibility. (From Dorland,28th ed) |
