Abstract
Salvia fruitcosa Mill.
(Syn. S. triloba L.) is one of the most used medicinal plant in Al-
Jabal Al-Akhdar, Libya. Plant materials were collected from three different
sites (Alwasita, Sidi Khaled and Wadi Al-kuf) of Al-Jabal Al-Akhdar area during
spring season of the year (2022). Essential oils (EOs) were isolated from fresh
aerial parts of the plant species growing wild by hydrodistillation. The
chemical composition of EOs has been carried out by Gas Chromatography and GC
Mass spectrometry (GC/MS). Chemical and physical properties of soil samples
from the three locations were estimated. One-way ANOVA method was conducted to
analyze the obtained data using with Least Significant Difference (LSD) test. The
results indicated that oil percentages obtained from the altitudes of Alwasita
(360 m), Sidi Khaled (385 m) and Wadi Al-kuf (600 m) were (2.24%, 2.00%, and
1.55%, respectively), so that Alwasita area revealed the greatest quantity, and
Wadi Al-kuf area represented the smallest quantity. EOs percentage and the main
components of EOs from different regions were compared. As the results of the
analyses 13 major components were determined, 1,8-cineole was the most abundant
constituent among them. All these components differed significatly at the three
different altitudes. Sand, pH, electrical conductivity, organic matter, Mg++
and K+ contents were highest in lower altitude (ALwasita area). As
the altitude increased, silt, clay, HCO3-, Cl-,
Ca++ and Na+ showed a statistically significant increase.
The range of soil pH (7.38-8.34) has a positive effect on oil yields. To improve
the production of the essence of the plant species, it is recommended that this
species to be cultivated in areas with alkaline soils and low altitude. In
conclusion, altitude and soil properties are important factors that should be
considered as they affected the yield, composition and biology of the plant
extracts.
