Chemical profile of Taxodium distichum winter cones

Abstract

This work is concerned with the chemical profile of Taxodium distichum winter cones. The extract obtained after maceration in absolute ethanol was subjected to qualitative analysis by gas chromatography/mass spectrometry and quantification was done by gas chromatography/ flame ionization detector. The chromatogram revealed the presence of 53 compounds, of which 33 compounds were identified. The extract contained oxygenated monoterpenes (12.42%), sesquiterpenes (5.18%), oxygenated sesquiterpenes (17.41%), diterpenes (1.15%), and oxygenated diterpenes (30.87%), while the amount of retinoic acid was 0.32%. Monoacylglycerols were detected in the amount of 4.32%. The most abundant compounds were: caryophyllene oxide (14.27%), 6,7-dehydro-ferruginol (12.49%), bornyl acetate (10.96%), 6- deoxy-taxodione (9.50%) and trans-caryophyllene (4.20%).
