Phytochemicals and Content.

Mentha Powder Extract INCI Name Mentha Arvensis Extract CAS 90063-97-1 EINECS ELINCS No 290-058-5 Mint Leaf Extract Mentha haplocalyx Mentha piperita Linn photo picture image Peppermint is a crossing between water mint, M. aquatica, and spearmint, M. spicata. The oldest descriptions are from the end of the 17'th century, and probably the crossing has occurred in England and was discovered there.

 Neolignan from Mentha haplocalyx:Lignans are distributed widely in the plant kingdom. By definition, lignans are dimers of phenylpropanoid (C6-C3) units linked by the central carbons of their side chains. Naturally occurring dimers that exhibit linkages other than this kind of linkage are known as neolignans.

 Peppermint oil is obtained by steam distillation of the flowering herb. It is an almost colourless to pale greenish-yellow liquid with a characteristic peppermint odour. The leading producer of peppermint oil is USA, where the annual production from M. piperita var. vulgaris is ca. 2000 t. Cultivation areas are located in the Midwest states Idaho, Oregon and Washington. Peppermint oil is used mainly for flavouring toothpaste, other oral hygiene products, and chewing gum. Smaller quantities are used for flavouring confectioneries.

 The main component of peppermint oil is (-)-menthol (ca. 50 %) followed by (-)-menthone (ca. 20 %) and (-)-menthyl acetate (ca. 10 %). A characteristic of peppermint oil is the high content of (+)-menthofurane (ca. 3 %, sometimes much higher) and a number of specific sesquiterpenes, one of them viridiflorol. The mint oils are among the most thoroughly investigated essential oils.

 The menthol molecule carries three asymmetric carbon atoms, and therefore exists in four diastereomeric pairs.

 (-)-Menthol is the only isomer having the special cooling effect upon the mucous membranes. (-)-Menthol forms large, transparent, colourless, tinkling, prismatic crystals with a melting point of 43 Deg C (picture on the right). Today it is synthesized from a number of terpenes using stereospecific hydrogenation catalysts based on rhodium(I)- or ruthenium(II)-complexes (Knowles and Noyori in 2001 got The Nobel Prize in chemistry for their research in asymmetric synthesis using these catalysts).
