This chemotype was found to be rich in camphor (winter 48.9%, summer 58.9%), 1,8-cineole (winter 22.2%, summer 14.8%), and limonene (winter 5.5%, summer 5.6%). The yield of oil was observed to be more in summer (0.8%) than in winter (0.6%). On shade drying of the leaves, no effect was observed in the yield of oil in winter season. However, in summer, yield was slightly reduced on drying (from 0.8% to 0.6%). Camphor, the major constituent of the oil, showed slight degradation in quantity during drying in both winter and summer seasons.
