Antifungal activities of essential oil from Litsea cubeba Pers. fruits against wood decay fungi.
IT has been known that plants contain bioactive compounds and have the potential to be used for many applications such as nutritional supplements, medicines, aroma therapy, pesticides and food preservatives. Litsea, a genus of Lauraceae, contains 11 species in Taiwan. Several species in this genus have been studied for their pharmaceutical potentials. Litsea cubeba Pers. is a small tree with ginger-spicy fruits used as the ingredients for soap, perfume, insect repellent and food flavor additive. To exam the antifungal activity of fruit essential oil from Litsea cubeba Pers., the essential oil was extracted from the fruits by steam distillation and antifungal activity was evaluated by agar plate assay. Results of the antifungal tests revealed that the antifungal indices of the fruit essential oil at 300 µg/ml against two strains of white rot fungi, Lenzites betulina and Trametes versicolor, were both 100%, while at 200 µg/ml its antifungal indices against two strains of brown rot fungi, Laetiporus sulphureus and Fomitopsis pinicola, were also 100%. The fruit oil processed the strongest antifungal activity against F. pinicola among the tested wood decay fungi. The IC50 (50% of inhibitory concentration) values of essential oil against L. sulphureus, L. betulina, T. versicolor and F. pinicola, were 79.4, 122.6, 102.5 and 35.0 μg/ml, respectively.
