dc.description.abstractPittosporum tobira L. (P. tobira) leaves were tested for essential oil and chemical composition monthly for 12 months. Leaves had 0.12–0.25% essential oil depending on the month. January, December, and February leaves had the most essential oil (0.25–0.23%). Low temperatures increased volatile oil content, while high temperatures decreased it. P. tobira leaf volatile oil had 45 components. Sesquiterpenes were the most abundant terpene group (34.93%), with the highest concentrations in May (38.75%) and the lowest in January (30.50%). Alkanes followed (22.1%). This group's highest values (23.81%) were again found in May. Oxygenated sesquiterpenes had the highest September values (21.32%). When analyzed separately, viridiflorol (13.34%), nonane (11.48%), undecane (9.99%), α-pinene (6.59%), and α-cubebene (6.02%) were the main components. The volatile oil of P. tobira leaves had the highest viridiflorol (18.64%) in October and the highest nonane (13.79%) in February and December. June had the highest α-pinene (8.68%) and α-cubebene (7.88%) ratios. Thus, Mediterranean-grown P. tobira leaves had different volatile oil and volatile components each month. This plant's leaves should be studied in months with the highest volatile components.
