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

Abstract

Green and eco-friendly synthesis of palladium nanoparticles NPs is carried out under

facile and eco-friendly conditions using an aqueous solution of

Salvadora persica L. (SP) root

extract (RE) as a bioreductant, which is commonly known as Miswak. The as-synthesized Pd

NPs were characterized using various spectroscopic and microscopic techniques, including, UV–

Vis spectroscopy, FT-IR spectroscopy, XRD, ICP-MS and TEM. Detailed investigations of the
