“…The chemical components of L. petersonii, E. citriodora and M. quinquenervia have been well studied. 8,[21][22] Similar results were obtained in our analysis, although there were some differences in the ratio of chemicals. Ogihara and Takeda 23 previously reported that the essential oil content can vary markedly, depending on growing conditions.…”

“…E. citridora and M. quinquenervia revealed weak fungicidal activity, but the other Myrtaceae plant essential oils show no antifungal activity, although antifungal activities of plant essential oils belonging to Myrtaceae have been reported in previous studies. 4,8,[16][17] There are no reports on antifungal activity of L. petersonii and M. quinquenervia essential oils and their components.…”

“…Many plant essential oils belonging to Myrtaceae species have been reported to have diverse bioactivity, such as insecticidal, antifungal and nematicidal activity. [7][8][9] In this study, we assessed the fungicidal activity of 11 Myrtaceae plant essential oils and their components against three phytopathogenic fungi to find new types of disease control alternatives.…”

Commercial plant essential oils obtained from 11 Myrtaceae plant species were tested for their antifungal activity against Phytophthora cactorum, Cryponectria parasitica and Fusarium circinatum. Good antifungal activity against Phytophthora cactorum was achieved with the essential oil derived from Leptospermum petersonii at 28 × 10 −3 mg/ml air concentration. Inhibition rates of Eucalyptus citriodora and Melaleuca quinquenervia were 35.4% and 33.6% at 28 × 10 −3 mg/ml air concentration, respectively. In a test with C. parasitica, inhibition rates of E. citriodora and L. petersonii were 29.4% and 38.5%, respectively. Only L. petersonii essential oil showed antifungal activity against F. circinatum. Analysis by gas chromatography-mass spectrometry led to identification of 16, 15 and 12 compounds, respectively, in the oils of L. petersonii, M. quinquenervia and E. citriodora. The antifungal activity of the identified compounds was tested individually using standard or synthesized compounds. The inhibition rates of citronellol, neral, geraniol and geranial were 100% against P. cactorum at 28 × 10 −3 mg/ml air concentration. In a test with C. parasitica, the inhibition rates of neral and geranial were 61.7% and 68.9% at 28 × 10 −3 mg/ml air concentration.

“…C. formosensis, known as the Taiwan red cypress, is one of the major forest trees indigenous to the high mountain area of Taiwan [1]. It has a thin bark and pale-pinkish-colored wood and is distributed in mid-elevation (1500 -2150 m above sea level) mountain forests in Taiwan [2]. Kafuka and Ichikawa [3] first reported the chemical composition of C. formosensis.…”

The species differentiation between Chamaecyparis formosensis, C. obtusa var. formosana, and C. obtusa, based on the composition of the leaf essential oils, was studied. The characterization of the oils by GC-FID and GC/MS analyses showed remarkable differences between these three essential oils. Cluster analysis (CA) and principal-component analysis (PCA) distinguished three groups of essential oils. The C. formosensis oil was dominated by α-pinene while those isolated from C. obtusa var. formosana and C. obtusa were characterized by high levels of (-)-thujopsene and α-terpinyl acetate, respectively. Moreover, the phylogenetic relationships of the genus Chamaecyparis were in agreement with previous findings based on morphological and molecular evidence. In addition, the essential oils from C. obtusa var. formosana could be classified into three chemical types, according to their different characteristic main compounds (β-elemol, (-)-thujopsene, and cis-thujopsenal). The biochemical correlations between the major constituents of the Chamaecyparis species were examined and their relationship is discussed.
