Abstract: Rosemary (Rosmarinus officinalis Linn.) leaves are well known flavouring agent for different type of dishes. The volatile oil from the leaves is used in perfumery and medicine. In order to find best drying method for rosemary leaves, different approaches, viz. shade, sun, microwave, hot air and oven drying were compared. The essential oil content was found to vary from 0.18 to 1.1% under different methods of drying. The essential obtained from hydrodistillation of dried leaves was analysed by GC and GC-MS. The major components of the oils were 1,8-cineole, camphor, α-pinene and verbenone. The quantitative composition of the oils was significantly affected by mode of drying. The monoterpene hydrocarbons were dominated in the fresh, shade and sun dried leaves (24.7 - 25%) whereas oxygenated monoterpenes were found to be higher in microwave and oven dried leaves (83.6 and 82.4%, respectively).
