Volatile constituents of brazilian piperaceae. Part 4. Essential oil composition of piper dactylostigmum, P. Plurinervosum and P. Vitaceum

Abstract

The essential oils of Piper dactylostigmum Yuncker, P. plurinervosum Yuncker and P. vitaceum Yuncker collected at Amazonas State, Brazil, were steam distillated and analyzed by GC/MS. The volatile composition of the oil of P. dactylostigmum was constituted only of sesquiterpenes where α-cadinol (21.7%) was the most abundant. The oil of P. plurinervosum was dominated by 1,8-cineole (31.6%). The main components identified in the oil of P. vitaceum were limonene (33.2%), p-cymene (12.8%) and (E)-nerolidol (20.6%). © 2000, Taylor & Francis Group, LLC. All rights reserved.
