l-Citronellol is a citronellol that is oct-6-ene substituted by a hydroxy group at position 1 and methyl groups at positions 3 and 7 (the 3S-enantiomer).

It is an enantiomer of a (R)-(+)-citronellol.

l-Limonene is the optical isomer of Limonene. It is classified as three types: l-Limonene, d-Limonene optical isomers and one racemic.

It is a colorless to pale yellow liquid with strong fruity and citrus odor.

d-Limonene is naturally found in Pine needle oil, Turpentine, Cajeput oil and other essential oils. l-Limonene presents in essential oil of citrus, such as mandarin oil and sweet orange oil.
