Boutoub, Oumaima; El-Guendouz, Soukaïna; Matos, Isabel; El Ghadraoui, Lahsen; Costa, Maria Clara; Carlier, Jorge D.; Faleiro, Maria LeonorAlthough the plants of the genus Euphorbia are largely exploited by therapists in Morocco, the composition and antibacterial activities of propolis from these plants are still unknown. To address this gap, this study aimed to characterize the pollen type, the volatile compounds, and the phenolic and mineral profiles of three Euphorbia propolis samples collected in Morocco and evaluate their antimicrobial activi...
Biochemical characterization of Euphorbia resinifera floral cyathia
Boutoub, Oumaima; Jadhav, Sagar; Zheng, Xiongjie; El Ghadraoui, Lahsen; Al Babili, Salim; Fernie, Alisdair R.; Figueiredo, Ana Cristina; Miguel, MariaEuphorbia resinifera O. Berg is a plant endemic to the Northern and Central regions of Morocco known since the ancient Roman and Greek times for secreting a poisonous latex containing resiniferatoxin. However, E. resinifera pseudo -inflorescences called cyathia are devoid of laticifers and, therefore, do not secrete latex. Instead, they exudate nectar that local honey bees collect and craft into honey. Honey an...

Study of chemical composition and biological activities of Euphorbia resinifera...
Boutoub, OumaimaEuphorbia officinarum and Euphorbia resinifera are two species found in Morocco. They have been used in traditional medicine. Reports indicate the use of Euphorbia officinarum for the treatment of wounds, skin infections and abscesses and the aerial parts of Euphorbia resinifera in combination with honey or extracts obtained by decoction have been used by patients in Morocco to treat cancer. The “Morocco Green ...
Response surface methodology (RSM) for optimization of Euphorbia resinifera and...
Boutoub, Oumaima; AAZZA, Smail; EL-GUENDOUZ, Soukaina; El Ghadraoui, Lahsen; Miguel, MariaBackground: Euphorbia is one of the plants most used by herbalists and therapists in Morocco. Objectives: The aerial part of two plant samples (Euphorbia resinifera and Euphorbia officinarum) collected in Morocco was examined for the solvent effect, extraction time, and plant concentration in order to determine the best extraction conditions. Materials and Methods: To achieve this goal, a response surface metho...
Biological properties of latex, aqueous extracts and bee products of Euphorbia ...
Boutoub, Oumaima; Ghadraoui, Lahsen El; Miguel, Maria GracaEuphorbia officinarum L. is a Moroccan endemic plant known as “Tikiout” and “Daghmus” that can also be found in Mauritania, Western Sahara, and Algeria. In the present review, “Euphorbia officinarum”, “metabolites” “hemisynthesis” were the keywords used for the research in the Web search engine Google Scholar and in the database Web of Science. Triterpenes, phytosterols and ingol diterpenes were isolated and id...
Antioxidant activity and enzyme inhibitory potential of Euphorbia resinifera an...
Boutoub, Oumaima; El-Guendouz, Soukaïna; Estevinho, Leticia M.; Paula, Vanessa B.; Aazza, Smail; El Ghadraoui, Lahsen; Rodrigues, Brígida; Raposo, SaraNatural products may be applied in a wide range of domains, from agriculture to food and pharmaceutical industries. In this study, the antioxidant properties and the capacity to inhibit some enzymatic activities of Euphorbia resinifera and Euphorbia officinarum aqueous extracts and honeys were assessed. The physicochemical characteristics were also evaluated. Higher amounts of iron, copper and aluminium were de...
Comparative study of the antioxidant and enzyme inhibitory activities of two ty...
Boutoub, Oumaima; El-Guendouz, Soukaïna; Manhita, Ana; Dias, Cristina Barrocas; Estevinho, Leticia M.; Paula, Vanessa B.; Carlier, Jorge D.Honey is a natural food product very famous for its health benefits for being an important source of antioxidant and phenolic compounds. Euphorbia honeys obtained from different regions of Morocco were evaluated for their ability to inhibit acetylcholinesterase, lipoxygenase, tyrosinase and xanthine oxidase activities. Their antioxidant properties were evaluated using the: 2,2-diphenyl- 1-picrylhydrazyl (DPPH) ...
