General description

(R)-(+)-Limonene is present in the peel oil from citrus fruits. It is the most commonly used fragrance materials in technical products and in fine fragrances. It is the major constituent of the essential oil extracted from Anethum sowa Roxb. (Indian dill). Racemic limonene undergoes enantio-selective and enantio-specific conversion to (R)-(+)-α-terpineol byPenicillium digitatum mycelia. Biotransformation of (R)-(+)- and (S)-(-)-limonene by fungi has been investigated.
(R)-(+)-Limonene is an optically active (R) form of limonene. Limonene is a 10-carbon cyclohexanoid monoterpene. It is widely employed in cosmetic industry.

Application

(R)-(+)-Limonene has been used to investigate the in vitro and in vivo action of limonene against Leishmania species.

The biotransformation of (R)-(-)- and (S)-(-)-limonene by fungi was investigated. More than 60 fungal cultures were screened for their ability to bioconvert the substrate, using solid phase microextraction as the monitoring technique. After screening, the best fungal strains were selected
