Phytochemical Investigation of Thymus zygis L. and Salvia officinalis L. Collected from Fez-Meknes Region, Morocco

Abstract

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

Innovative date syrup processing with ohmic heating technology: Physiochemical characteristics, yield optimization, and sensory attributes

“…Wavelengths appeared in the CH method from 2075.03 to 2669, Nikalje, Kumar [ 49 ] indicated that wavelengths from 2426.98 to 2361.41 refer to P –H phosphine. Benabderrahmane, Atmani [ 50 ] indicated that the S –H, O –H, C –H, and N –H functional groups fall within the range of 2500–4000 cm −1 , while the C C and C O groups fall within the range of 1500–2000 cm −1 . In general, the principal results found to be O –H stretch functional group (alcohol) at wave number 3594.66 cm −1 , N C S (Isothiocyanate) at wave number 2116.49 cm −1 , S –S (Aryl disulfides) at wave number 476.331 cm −1 for date syrup treated by OH.…”

Assessing the Impact of Organic and Chemical Herbicides on Agronomic Parameters, Yield, and Weed Control Efficiency in Lentil (Lens culinaris Medik.) under a Direct-Seeding System: A Comparative analysis

“…Adhering to the methodology [5,15], infrared spectra corresponding to lentil seed proteins were obtained through FTIR analysis. The Fourier Transform Infrared Spectrometer (FTIR) with an ATR (Attenuated Total Reflection) Smart Orbit accessory was employed for this purpose.…”

Chemical and Elemental Composition of<i> Ammi visnaga</i> L. and <i>Calendula officinalis</i> L. from Meknes, Morocco

“…Carbon is the most abundant macro element for both samples. It makes with the hydrogen a fundamental building block of all organic compounds found in plants, including, hydrocarbons carbohydrates, lipids, proteins, and nucleic acids (Benabderrahmane et al, 2023;Mandal et al, 2017). It is obtained from the carbon dioxide in the air through the process of photosynthesis.…”

“…It is synthesized as a product of basic metabolic processes occurring in various subcellular locations (Mhamdi & Breusegem, 2018). Oxygen with hydrocarbons can undergo chemical reactions to form compounds with functional groups (Benabderrahmane et al, 2023).…”
