Essential oil composition of

 

Plectranthus asirensis grown in Saudi Arabia

was chemically analysed for the first time by various gas chromatography

techniques (GC–MS, GC–FID, Co–GC, LRI determination and database

and literature searches) using two different stationary phase columns

(polar and nonpolar). This analysis led to the characterisation of a total

of 124 components representing 98.5% of the total oil composition.

The results revealed that

 

P. asirensis oil was mainly dominated by

monoterpenoids (90.7%) in which most representative constituents

were thymol (66.0 ± 0.36%),

 

γ-terpinene (14.0 ± 0.18%), p-cymene

(5.2 ± 0.06%) and

 

β-caryophyllene (3.0 ± 0.03%). It is worth mentioning

here that this is the first report on the phytochemical constituents of

P. asirensis.
