In this study, anti-mildew fungal activities of the heartwood essential oil, and its constituents from Chamaecyparis formosensis were evaluated in vitro against 7 mildew fungi. The main compounds responsible for the anti-mildew fungal activities were isolated and identified. The heartwood essential oil of C. formosensis was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. The heartwood oil consisted primarily of myrtenol (18.4%), cis-myrtanol (14.0%), α-muurolol (13.8%), α-cadinol (12.7%), and chamaecynone (9.8%). The heartwood oil was shown to have excellent anti-mildew fungal activities. Further fractionation of the heartwood oil produced α-cadinol, chamaecynone, α-muurolol, τ-cadinol, and τ-muurolol. The 5 compounds exhibited very strong anti-mildew fungal activities. For the anti-mildew fungal activities of the heartwood oil, the active source compounds were determined to be α-cadinol, chamaecynone, α-muurolol, τ-cadinol, and τ-muurolol.

In this study, antipathogenic activities of the twig essential oil and its constituents from Chamaecyparis formosensis Matsum were evaluated in vitro against six plant pathogenic fungi. The essential oil from the fresh twigs was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Twenty-five compounds were identified, representing 98.9% of the oil. The main components were β-eudesmol (25.1%), τ-muurolol (21.6%), elemol (15.0%), totarol (14.9%), and α-cadinol (12.4%). The twig oil (500 μg/mL) showed growth inhibitory activity against the phytopathogenic fungi, Fusarium oxysporum, Pestalotiopsis funereal, and Ganoderma austral, with antifungal indices of 92.7%, 71.1%, and 87.7%, respectively. In addition, the oil suppressed totally the growth of Rhizoctonia solani, Colletotrichum gloeosporioides, and Fusarium solani. In order to ascertain the source compounds of these antipathogenic activities, the main components were individually evaluated. τ-Muurolol and α-cadinol exhibited excellent activity against F. oxysporum, R. solani, C. gloeosporioides, and F. solani, with IC50< 50 μg/mL. These compounds also efficiently inhibited the mycelial growths of P. funereal and G. austral. Thus, α-cadinol and τ-muurolol could be considered as potential natural fungicides for controlling fungal pathogens and worth.
