Phytochemical Analysis and Bioactive Properties of Flower Extracts, Compound, and Essential Oil.

New research is exploring the enhanced efficacy of antioxidant and antimicrobial compounds developed from flowers, a multifaceted source with pharmacological effects such as antioxidant and microbicide activity indexes showing diverse medical capabilities. The purpose of this study was to determine the chemical composition, isolate the active compounds, and evaluate their antioxidant properties as well as antibacterial potential through HPLC-MS in flower extract from . The extracts were analyzed by high-performance liquid chromatography (HPLC), and essential oil compounds were identified by gas chromatography (GC).

Proximate nutritive values, antioxidant capacity, antimicrobial properties and profiling the chemical content of cladodes and fruit peel by HPLC-DAD-ESI/MS analyses.

The study characterises the phenolic compounds in ethanol, butanol, and ethyl acetate extracts from the fruit peels and cladodes from Morocco using UHPLC/DAD/ESI-MS. Additionally, the study evaluates the antimicrobial and antioxidant activities of these extracts. Thirteen phenolic compounds were found in extracts, such as flavonoids (kaempferol 3-O-arabinoside, isorhamnetin rhamnosyl-rutinoside, quercetin 3-O-rutinoside, isorhamnetin-3-O-rutinoside, and isorhamnetin) and phenolic acid.

The essential oils yield of , and was different. gave a relatively higher yield (2.1 ± 0.

Developing a remotely sensed drought monitoring indicator for Morocco.

Drought is one of the most serious climatic and natural disasters inflicting serious impacts on the socio-economy of Morocco, which is characterized both by low-average annual rainfall and high irregularity in the spatial distribution and timing of precipitation across the country. This work aims to develop a comprehensive and integrated method for drought monitoring based on remote sensing techniques. The main input parameters are derived monthly from satellite data at the national scale and are then combined to generate a composite drought index presenting different severity classes of drought.
