Chemical Characterization and Antimicrobial Activity of Rhizome Essential Oils of Very Closely Allied Zingiberaceae Species Endemic to Borneo: Alpinia Ligulata K. Schum. and Alpinia nieuwenhuizii Val.

Two poorly studied, morphologically allied Alpinia species endemic to Borneo, viz., A. ligulata and A. nieuwenhuizii, were investigated here for their rhizome essential oil. The oil compositions and antimicrobial activities were compared with those of A. galanga, a better known plant. A fair number...
