Synthesis method:
Menthol mint oil purification from natural or synthetic method. Mint Labiatae plant aboveground part (stems; branches; leaves and inflorescence) obtained by steam distillation from the essential oils known crude mint oil, oil production rate is 0.5-0.6.

There are several methods of synthesis of thin and brain.
1 from citronellal manufacturing easy ring into different properties of isopulegol by citronellal, citronellal to dextral using an acid catalyst (such as silica gel) cyclizes sinistral isopulegol, separate the left-hand isopulegol, hydrogenation of l-menthol. The three-dimensional structure by thermal cracking of tutor can partially was transformed into dextral citronellal, recycling use.

2 from the thymol in manufacturing presence in m-cresol aluminum, m-cresol was on the alkylation reaction of thymol. By catalytic hydrogenation of all four stereoisomers of menthol (i.e. racemic menthol; racemic new menthol; racemic isomenthol and racemic neoisomenthol). The distillation, cancel the rotary menthol ester fraction, manufacturing after repeated re crystallization, separation and optical resolution of isomers. L menthol ester is separated, by saponification after menthol.

Menthol and racemic menthol can all be used as a toothpaste; perfume; aromatizing agent drinks and candy etc.. Used as a stimulant drug in medicine, applied to the skin or mucous membrane, have cool and refreshing and antipruritic effect; oral administration can be used as a carminative, used for headache and nasal; pharynx; laryngitis etc..
