Antibacterial activity of Dioscorea bulbifera Linn. extract and its active component flavanthrinin against skin-associated bacteria.

Background: Dioscorea bulbifera Linn. has been used for wound care in Thailand. However, a comprehensive evaluation of its antibacterial activity is required.

Variation in the Antibacterial and Antioxidant Activities of Essential Oils of Five New S.T. Blake Clones in Thailand.

oils are widely used for a variety of purposes. This study investigates the terpenoid compositions and antibacterial and antioxidant activities of eucalypt leaf oils extracted from four clones and one × hybrid clone grown in Thailand. According to GC/MS analysis, the oils were mainly composed of 1,8-cineole, -terpinyl acetate, -caryophyllene, and spathulenol, while 1,8-cineole, -terpinyl acetate, -cymene, and -terpinene were mostly identified in the hybrid oil.
