Abstract:
The experiment on influence of time and stage of flower harvest on oil yield, quality and screening of oil for its antibacterial properties of Cananga odorata HOOK. F. AND THOMSON. was carried out at the Department of Horticulture, GKVK campus, University of Agricultural sciences, Bangalore. The experiment consists of two seasons (October-December and March-May) with 6 treatment each and with 3 replications and FCRD was followed. In season 1, the highest oil percentage recorded was 1.87% with distillation of flowers at green stage at 12.00 noon during the months October-December. In season 2, the highest oil percentage recorded was 1.27% with distillation of flowers at green stage at 12.00 noon during the months March-May. GC-MS analysis showed that the percentage composition of specific constituents of oil from the present study was comparable with first grade oil of Ylang-ylang as per Madagascar standards. The oil extracted from both the stages of flower showed inhibitory effect against Bacillus cereus, Bacillus subtilis and Escherichia coli.
