Abstract
The medicinal effect of each of Cidir (Zizyphus spina-Christi) and Costus (Saussurea lappa) was used as traditional medicine in Saudi Arabia. The present study Cidir (Zizyphus spina-Christi) and Costus (Saussurea lappa) plants were analyzed for the chemical molecules. The best effective fraction were utilizing and identified as quantitative phytochemic alanalyses using gas chromatography-mass spectrometry (GC/MS) analytical methods, compare by database library mass spectra of the GC/MS identified compounds with those in the National Research center (NRC). The chemical analysis evidenced the presence of active compounds such as glycosides, saponin, tannins, phenols, terpenoids, alkaloid, steroids, and flavonoids in the aqueous extract of Costus and Cidir. Therefore, Cidir and Costus could be contemplating as a power source of herbal formula and pharmaceutical drug therapy product.
