Abstract

Growth inhibition and anti-aflatoxigenic activities of various extracts and steam distilled/essential oil of Piper guineense were assessed on Aspergillus flavus CBS 133921 and A. parvisclerotigenus CBS 135587 after determining the volatile compound profiles by gas chromatography/mass spectrometry. Twenty and 14 volatile compounds constituting 57.14% and 90.07% of the total extracted oils were identified in the hexane extract and hydro-distilled oil respectively. Sesquiterpene hydrocarbons and alcohols dominated the chemical profiles of both oils. The hexane extract had the highest (47.7–50.8%) significant (p<0> hexane extract > methanolic extract > defatted methanolic extract. Volatile compounds of P. guineense inhibit aflatoxigenic fungal growth and aflatoxin biosynthesis. To our knowledge, this is the first systematic and comparative report evaluating antifungal and antiaflatoxigenic activities of P. guineense extracts obtained via different techniques.
