2. Introduction
The purpose of this investigation is to extract the natural compound trimyristin, also called glyceryl trimyristate, from the spice nutmeg. Trimyristin is a trimester of glycerol and the fatty acid myristic acid. It will be extracted under reflux by combining nutmeg with diethyl ether, filtered to remove solid impurities, and collected by rotary evaporator. A melting point will be determined to give an indication of the purity of the sample.
