Peppermint oil is produced by steam distillation of the flowering herb Mentha x piperita L. It is an almost colorless to pale greenish-yellow liquid with a characteristic peppermint odor. 

Another favorite substance for medicine and cosmetics is menthol. It is obtained from a number of heibs, peppermint (Mentha x piperita L.) being the most common source (Fig. 2.13). The peppermint plant contains about 1-3 % essential oil, which can be obtained by a chemical separation method called steam distilla-tiom About half of the oil is menthol and its derivatives, terpenes, and flavonoids. Menthol has a pleasant odor and eooling effect, and these two properties are why...

Presumably the most studied essential oil plant is peppermint (Mentha x piperita L.). Already in the 1950s Lemli (1955) stated that the proportion of menthol to menthone in peppermint leaves changes in the course of the development toward higher menthol contents. Lawrence (2007) has just recently shown that from immature plants via mature to senescent plants the content of menthol increases (34.8-39.9 8.2%) and correspondingly the menthone content decreases dramatically (26.8-17.4-4.7%). At the same time, also an increase of menthyl acetate from 8.5% to 23.3% of the oil could be observed. At full flowering, the peppermint herb oil contains only 36.8% menthol but 21.8% menthone, 7.7% menthofuran, and almost 3% pulegone due to the fact that the flower oils are richer in...
