Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ 2215T HYMUS and Salvia are among the most popular plants both in traditional medicine and in the culinary arts. This study has the aims to detect the chemical composition of the extracts and the powder of Thymus zygis L. (T) and Salvia officinalis L. (S) collected from the Fez-Meknes region. Two extracts were prepared: aqueous and essential oil. Phytochemical tests were performed to qualitatively evaluate the presence or absence of phytoconstituents using standard methods. The essential oils were analyzed by gas chromatography-mass spectrometry (GC/MS). Two powder analyses were performed: Fourier transform infrared spectroscopy (FTIR) analysis and elemental analysis. The drying of both plants took a similar amount of time with a noticeable loss in weight for Salvia. The phytochemical screening revealed the abundant presence of terpenoids, catechic tannins, steroids and sterols in the two plants. GC/MS analysis showed richness in carvacrol for Thymus zygis L. and in thujone for Salvia officinalis L. The analysis by FTIR showed characteristic peak readings of various functional groups in the powders, citing proteins, aliphatic compounds, carbonyl compounds and aromatic rings. In the elemental analysis, there is a high carbon content for Thymus and Salvia

The powders of Ammi visnaga L. and Calendula officinalis L. plants collected from Meknes region were subjected to three types of analysis, including Fourier transforms infrared spectroscopy (FTIR) analysis, CHNS/O analysis, and ICP-AES analysis with the aim of comparing and giving an insight into the nutritional value, medicinal properties, and potential applications in different fields. The results of the FTIR analysis showed absorbance bands in the same wavelengths, but with different peaks, indicating the presence of long-chain linear aliphatic compounds, lipids, amides, aromatic compounds, and other functional groups in both plants. The CHNS/O analysis revealed high levels of carbon and oxygen, followed by hydrogen, nitrogen, and sulfur for both plants, with no significant differences in the values. The ICP analysis detected 16 minerals, including calcium, potassium, phosphorus, and magnesium in Ammi visnaga, and low levels of sodium in comparison to Calendula officinalis. Calendula officinalis accumulated more aluminum and lead than Ammi visnaga, indicating higher tolerance to contaminations. Zinc, iron, manganese, and copper were important micronutrients present in both plants. The findings of this study suggest that both plants have significant amounts of phytochemical compounds and minerals, which could be beneficial for their potential use in the pharmaceutical, nutraceutical, and cosmetic industries.
