Abstract

Piper capense is used traditionally as spice and for the treatment of infectious diseases in different parts of the world. It is among the species piper which adapted to the climate of Ethiopia. Assessment tells that the plant is used for the remedy of various ailments in different parts of the country. The essential oil obtained by hydrodistillation of the fruit of Piper capense grown in Ethiopia was analyzed using GC&GC-MS which showed the presence of 32 predominant constituents like safrole, α-cubebene, α-copaene, β-caryophyllene, germacrene D, β-bisabolene, isoshyobunone.

Highlights

Piper capense is among the genus Piper which is found in tropic and sub tropic regions in both hemisphere
Monoterpene hydrocarbons were the main group of constituents in the sample of P. capense. β -Pinene (32.5%) and β-caryophyllene (12.6%) were the major compounds in the volatile oil of P. capense
Phytochemical analyses have shown that terpenoids are the most frequently chemical composition of the essential oils from P. capense and it was reported that these compounds could be responsible for the antimicrobial activity [8]

Summary

Introduction

Piper capense is among the genus Piper which is found in tropic and sub tropic regions in both hemisphere It is classified under the family of piperaceae [1]. In Ethiopia P. capense is mostly cultivated and found in natural forest of Keffa zone of the SNNPR, Bonga's coffee forest of the South West of Ethiopia and in Jimma zone It is known by different local names including Turfo (Afan Oromo and Kefinya), Timiz (Amharic) and Tonjo (Tigrinya) [3]. The GC and GC-MS analysis of the essential oils from the fruits of Piper capense, grown in Cameroon were rich in α-pinene (5.6 - 12.3%) and β-pinene (6.7 - 59.3%). The essential oil obtained from the leaves of P. capense was largely composed of α-pinene (12.8%), β -pinene (50.1%) and β-caryophyllene (12.4%). Phytochemical analyses have shown that terpenoids are the most frequently chemical composition of the essential oils from P. capense and it was reported that these compounds could be responsible for the antimicrobial activity [8]
