【 摘 要 】

Curcuma longa (turmeric) has been used in Chinese traditional medicine and Ayurvedic medicine for many years. Methods: The leaf essential oil of C. longa from southern Nigeria was obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry (GC-MS). The essential oil was screened for in vitro antibacterial, antifungal, and cytotoxic activities. The major components in C. longa leaf oil were ar-turmerone (63.4%), α-turmerone (13.7%), and β-turmerone (12.6%). A cluster analysis has revealed this to be a new essential oil chemotype of C. longa. The leaf oil showed notable antibacterial activity to Bacillus cereus and Staphylococcus aureus, antifungal activity to Aspergillus niger, and cytotoxic activity to Hs 578T (breast tumor) and PC-3 (prostate tumor) cells. The ar-turmerone-rich leaf essential oil of C. longa from Nigeria has shown potent biological activity and therapeutic promise.
