Triacylbenzenes and long-chain volatile ketones from Cochlospermum tinctorium rhizome

The composition of the volatile fraction from Cochlospermum tinctorium rhizome was investigated by GC and GC-MS; among 11 constituents detected, eight were identified as straight chain ketonic compounds. In addition, five triacylenzenes were isolated from a petrol extract of the rhizome, separated by HPLC and identified by their spectral data.
