The chemical components of essential oils derived from leaves and flowers of

 

Lantana

camara

 

growing in Saudi Arabia are analyzed for the first time using gas chromatography techniques

(GC–MS, GC–FID, Co-GC, LRI determination, and database and literature searches) on

two different stationary phase columns (polar and nonpolar). This analysis led to the identification

of total 163 compounds from leaves and flowers oils. 134 compounds were identified in the oil

obtained from leaves of

 

L. camara, whereas 127 compounds were identified in the oil obtained from

flowers; these compounds account for 96.3% and 95.3% of the oil composition, respectively. The

major components in the oil from leaves were

 

cis-3-hexen-1-ol (11.3%), 1-octen-3-ol (8.7%),

spathulenol (8.6%), caryophyllene oxide (7.5%) and 1-hexanol (5.8%). In contrast, the major compounds

in the flowers oil were caryophyllene oxide (10.6%),

 

b-caryophyllene (9.7%), spathulenol

(8.6%),

 

c-cadinene (5.6%) and trans-b-farnesene (5.0%). To the best of our knowledge, cis-3-

hexen-1-ol and 1-octen-3-ol that were identified as major components in this study have not been

reported earlier from

 

Lantana oils.
