From this essential oil, menthol crystals were prepared by chilling at different temperatures and yield of both essential oil and menthol crystals was 2.4 and 52.3%, respectively. Various physical constants of menthol crystals like refractive index, melting point, specific gravity and optical rotation were also determined. The crystals of menthol were colorless hexagonal needle like with pleasant minty odour and slightly pungent taste and possessed strong cooling effect.
