Trimyristin is an ester with the chemical formula C45H86O6. It is a saturated fat which is the triglyceride of myristic acid. Trimyristin is found naturally in many vegetable fats and oils. Trimyristin is a white to yellowish-gray solid that is insoluble in water, but soluble in ethanol, benzene, chloroform, dichloromethane, and ether.

The isolation of trimyristin from powdered nutmeg is a common introductory-level college organic chemistry experiment. It is an uncommonly simple natural product extraction because nutmeg oil generally consists of over eighty percent trimyristin. Trimyristin makes up between 20-25% of the overall mass of dried, ground nutmeg. Separation is generally effected by steam distillation and purification uses extraction from ether followed by distillation or rotary evaporation to remove the volatile solvent. The extraction of trimyristin can also be done with diethyl ether at room temperature, due to its high solubility in the ether. The experiment is frequently included in curricula, both for its relative ease and to provide instruction in these techniques.
