Chemical composition of the essential oil fromTagetes mandonii Sch. Bip. (Asteraceae)

Abstract

The essential oil from aerial parts of Tagetes mandonii Sch. Bip. (Asteraceae) was obtained by hydrodistillation. The oil content was 0.43% (v/w), on a dry weight basis. The oil composition was analysed by GC and GC–MS; 62 of the 71 compounds detected were identified, accounting for 96.8% of the oil, cis- (11.8%) and trans-ocimene (15.2%) were the main components, with appreciable amounts of ocimenones (12.9%), tagetones (12.5%), limonene (7.9%) and, in sesquiterpene fraction, spathulenol (6.9%). cis-Anethole (9.2%) is the main constituent of the phenylpropanoid group (12.7%).
