The chemical composition and in vitro anti-inflammatory, antioxidant and antimicrobial activities of the leaf essential oil of Machilus konishii has been investigated. The essential oil was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC–FID and GC–MS. Sixty-six compounds were identified, representing 100% of the oil. The main components identified were α-pinene (33.9%), β-pinene (13.9%), and thymol (12.0%). The leaf oil was able to reduce nitric oxide production by lipopolysaccharide-activated murine macrophages RAW 264.7 without reducing the cell viability. In addition, the leaf oil showed strong antioxidant and antimicrobial activities. The major ingredient of the oil that was responsible for the anti-inflammatory, antioxidant and antimicrobial activities was thymol.

The chemical composition and in vitro anti-inflammatory, antioxidant and antimicrobial activities of the essential oils isolated from the leaf and twig of Cupressus cashmeriana have been investigated. The essential oils were isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC–FID and GC–MS, respectively. The leaf oil mainly consisted of α-pinene (21.8%), epizonarene (8.0%), sabinene (7.9%), limonene (7.6%), γ-terpinene (7.0%), and allo-aromadendrene (7.0%); the twig oil was mostly carvacrol methyl ether (35.4%), manool (16.1%), carvacrol (14.2%), and (2 Z,6 E)-farnesol (6.9%). Twig oil, but not leaf oil, was able to reduce nitric oxide production by lipopolysaccharide-activated murine macrophages RAW 264.7 without reducing the cell viability. In addition, twig oil showed better antioxidant and antimicrobial activities than leaf oil. The major ingredient of the twig oil that was responsible for the anti-inflammatory, antioxidant and antimicrobial activities was carvacrol.
