Trimyristin is obtained from nutmeg by extraction with boiling ether. i Saponification of trimyristin produces the salt of myristic acid (CH 3 -(CH 2 ) 12 -CO 2 Na), which is a soap. Tests with sodium myristate: Results and Discussions: Soaps are usually obtained by saponification (basic hydrolysis) of commercially available triglycerides (fats and oils). Ground nutmeg was heated under reflux for 30 minutes with diethyl ether. The solid was decanted and washed with diethyl ether, distilled to remove the solvent, and then recrystallized from 95% ethanol to produce trimyristin. A spot of this was developed in hexane on a TLC plate to determine characteristics of trimyristin and R f s were calculated. To obtain sodium myristate, the solid was heated with NaOH and 95% ethanol and then the resulting solid was cooled and mixed with water and then saturated NaCl, and then filtered and washed with cold water. Three different compounds were added to samples of sodium myristate as a test: vegetable oil, 1%FeCl3, and 1% CaCl2. The sodium myristate was then converted to myristic acid with 6M aqueous HCl until pH was below 7, washed with water, and tested on a TLC plate.
