Background: Naturotherapy involving geo-materials has been a longstanding practice, originating from antiquity. El Hammira, a striking red medicinal stone from Southern Morocco, continues to be a vital component in traditional Moroccan Saharan health practices. Despite its ongoing significance, the exact chemical composition and therapeutic efficac...

In order to search for new chemotypes and to carry out a comparative study with the literature, the current study investigated the chemical composition of the essential oil of the flowers of Daucus carota (L.) ssp. carota using gas chromatography coupled with mass spectrometry (GC-MS). Moreover, the antimicrobial and insecticidal potentials of esse...

The essential oil and the aqueous and ethanolic extracts obtained from the aerial parts of Pelargonium graveolens cultivated in Morocco were studied for their antioxidant and insecticidal activity against rice weevils (Sitophylus oryzae). The total phenolic content of the extracts was determined by a spectrophotometric method and the phenolic compo...

Medicinal plants are considered an essential source of raw material for the discovery of new molecules necessary for the development of future remedies. Among these plants we find Urtica dioica (L.), Pelargonium graveolens, Taxus baccata (L.), Artemisia herba alba asso, Dysphania ambrosioids (L.) and Daucus carota (L.) ssp. carota which have variou...

The study of the inhibition of the ecological corrosion of steel in the 1M hydrochloric acid medium by aqueous and ethanolic extracts of Pelargonium graveolens was carried out using gravimetric, electrochemical, high-performance liquid chromatography (HPLC), and scanning electron microscopy (SEM/EDX). The results of this study showed that inhibitor...

This work focuses on the search for natural molecules with biological activity that can be used to find alternatives to synthetic products by studying the chemical composition and evaluating the antioxidant and antibacterial activity of the extract of Taxus baccata (L.). HPLCUV chromatography was employed to determine its chemical composition, whil...

This work aims to study the chemical composition and evaluate the antibacterial activity of Pelargonium graveolens essential oil and its fractions collected in the Er-Rachidia region of Morocco. GC-MS analysis of Pelargonium graveolens essential oil and its fractions yielded majority compounds such as; epi-γ-Eudesmol (16.67 %), Geraniol (12.54 %),...

Pelargonium graveoiens (rose-scented pelargonium) is a plant that belongs to the Geraniaceae family native to South Africa. It is recognized for its aroma and essential oil which is widely used in the cosmetic industry, aromatherapy and as a food flavoring agent. It is also known for its antifungal, antimicrobial, anti-inflammatory and antispasmodi...

Lavandula stoechas and Teucrium Poliums are two plants that belong to the Lamiaceae family. They are widely used in traditional medicine. They mainly have analgesic, anti-infectious and antispasmodic properties. The phytochemical results showed that Lavandula stoechas and Teucrium Poliums are rich in alkaloids, catechetical tannins, flavonoids and...

Abstract: Today, medicinal plants are still the primary reservoir of new drugs. They are considered an essential source of raw material for the discover...

The main purpose of this study was to determine the content of various extracts of Pulicaria mauritanica and Lavandula mairie on polyphenols and flavonoids, and also to assess their antioxidant and antibacterial activities. The various extracts were prepared from aerial part using solvents of different polarity (hexane, ethyl acetate and ethanol),...
