Isolation, NMR Characterization, and Bioactivity of a Flavonoid Triglycoside from Stems: Antioxidant and Antiproliferative Effects on MDA-MB-231 Breast Cancer Cells.

Plant extracts are considered as a large source of active biomolecules, especially in phytosanitary and pharmacological fields. is a woody Saharan plant located in the big desert of North Africa. Our previous research paper proved the richness of the methanol extract obtained from the stems in flavonoids and phenolic compounds as well as its remarkable antioxidant activity.

Effect of the Harvest Season of Stems on Antioxidant and Antimicrobial Activities: Phytochemical Profiling of Their Ethyl Acetate Extracts.

stems were harvested in two seasons: winter and spring (February and May 2021). In this study, we investigated the antioxidant (DPPH, ABTS, FRAP and TAC) and antimicrobial activities, total phenolic contents and total flavonoid contents of the obtained extracts (hexane, ethyl acetate and methanol). The results showed that ethyl acetate extract from stems harvested in winter exhibited the highest antioxidant activity, while ethyl acetate extract from the stems harvested in spring showed the most potent antibacterial and antifungal activities.

Antioxidant and Antimicrobial Activities of Aerial Part Extracts and Characterization by LC-HESI-MS of Its Acetone Extract.

The phytochemical analysis of antioxidant and antibacterial activities of aerial part extracts constitute the focus of this research. The chemical composition of an acetone extract was investigated using LC-HESI-MS, which revealed the presence of 70 compounds. The major identified components were tannin derivatives.

HESI-MS/MS Analysis of Phenolic Compounds from Fruits Extracts and Evaluation of Their Antioxidant Activities.

Considering medicinal plants as an inexhaustible source of active ingredients that may be easily isolated using simple and inexpensive techniques, phytotherapy is becoming increasingly popular. Various experimental approaches and analytical methods have been used to demonstrate that the genus Calendula (Asteraceae) has a particular richness in active ingredients, especially phenolic compounds, which justifies the growing interest in scientific studies on this genus' species. From a chemical and biological viewpoint, is a little-studied plant.
