Abstract

The antifungal activity of leaf oils from different provenances of Cinnamomum osmophloeum was evaluated against Phellinus noxius and their chemical polymorphism. C. osmophloeum leaf oils of 15 provenances and their relative contents were classified into eight chemotypes, namely cinnamaldehyde, cinnamaldehyde/linalool, linalool, cinnamaldehyde/cinnamyl acetate, linalool/camphor, camphor/bornyl acetate, 1,8-cineole/p-cymene, and mixed types according to GC-MS, CA, and PCA. It was found that leaf oils of both cinnamaldehyde and cinnamaldehyde/cinnamyl acetate types had excellent inhibitory effects against P. noxius, and their IC50 values were 119.5 and 154.1 µg/ml, respectively. Furthermore, trans-cinnamaldehyde possessed the strongest antifungal activity among the constituents against P. noxius, and its IC50 values were 116.0 µg/ml.
