Abstract: | The chemical compositions of essential oil, concrete, absolute from the capitula of Tagetes patula (family Asteraceae) were analysed by GC-FID and GC/MS. The major compounds identified were (Z)-β-ocimene, (E)-β-ocimene, terpinolene, (Z)-ocimenone, (E)-ocimenone and δ-elemene. In addition, the volatiles of live and plucked capitula (flowers) were analysed by SPME technique using PDMS/DVB/CAR fiber. The SPME-GC-FID analyses of live capitula showed that the volatiles were rich in monoterpenoids in comparison to the plucked capitula. On the other hand, the plucked capitula recorded with significant increase in sesquiterpenoids in comparison to the living capitula. |
