Analysis by GC–MS of the hexane extract of the aerial parts of Aristolochia acutifolia Duchtr.

Abstract

Qualitative analysis by GC–MS of the three non-polar fractions from the hexane extract of Aristolochia acutifolia Duchtr. was carried out and 47 constituents were identified. The major groups of constituents identified away these fractions were sesquiterpenes (spathulenol, 23.1%; β-bisabolene, 9.0%; α-eudesmol, 6.9%; α-selinene, 5.2%; and trans-α-bergamotene, 5.1%), esters (ethyl hexadecanoate, 23.0%; ethyl 9-octadecenoate, 11.6%; and methyl hexadecanoate, 7.9%), phenylpropanoids (myristicin, 35.3%; and elemicin, 15.8%), carboxilic acids (oleic, 22.8%; and palmitic acids, 20.3%), and n-alkanes (pentadecane, 11.7%). Some constituents identified are described for the first time in this genus. Copyright © 2001 John Wiley & Sons, Ltd.
