Chemical compositions and antibacterial activity of the leaf and stem oils of piper porphyrophyllum (Lindl.) Ne Br.E

The essential oils obtained by hydrodistillation from the fresh leaf and stem of Piper porphy-rophyllum N.E. Br. were analyzed by GC and GC/MS. Thirty four constituents were identified in the leaf oil, while thirty eight constitue nts were identified in the stems oil. The most abundant components in...
