The essential oil from the dried leaves of Calotropis procera was analyzed by GC-MS. The three major components in the oil are phytol and its isomers 3, 7, 11, 15-tetramethyl-2-hexadecene-1-ol (37.59%) and 6, 10, 14-trimethyl-2-pentadecanone (15.31%). The essential oil was collected in two modes: one mode is a continuous distillation for 4 h and another mode involves hourly collection of fractions over a period of 4 h, thus providing fractionated samples. This novel procedure makes it possible to identify other components which might not have been detected in the unfractionated sample. Such other components include tetradecanal, isophytol and 1-docosanol. The usefulness of phytol in the management of inflammatory diseases suggests that the plant may be useful in the management of arthritis. 6, 10, 14-trimethyl-2-pentadecanone, a mosquito repellent may be useful for malaria control.
