Composition and antimicrobial activity of the essential oil of Cistus creticus subsp. eriocephalus
Abstract:
The chemical composition of the essential oil of the leaves of Cistus creticus subsp. eriocephalus (Viv.) Greuter & Burdet, (Cistaceae), was investigated by GC/MS. Thirty-nine components were identified, representing 73.9% (based on % total peak area by GC) of the oil composition. The main components of the oil were alpha-cadinene (6.5%), delta-cadinene (5.6%), viridiflorol (5.4%), bulnesol (6.3%), ledol (3.8%), alpha-copaene (3.8%), beta-selinene (3.4%), cubenene (3.3%), manoyl oxide (9.9%) and 13-epi-manoyl oxide (3.4%). Antibacterial studies were carried out in vitro against Gram-positive and Gram-negative organisms.
