Seeds of Hyoscyamus muticus L. subsp. falezlez: Morpho-Anatomical Features, Phytochemical Investigation and Evidence for Antioxidant Activities.

This work aims to describe the morpho-anatomy and determine the mineral composition of H. muticus L. subsp.

Evaluation of the level of biomolecules isolated from date palm seeds () and Antioxidant property.

Date palm fruits and by-products such as seeds are a source of various elements with significant nutritional values like fibres, minerals, essential fatty acids, amino acids and phenolic compounds. The experimental part was carried out on date palm seeds from Bent Kbala cultivar, the chemical composition of the organic fraction was determined using the method of UV-visible spectrophotometer, thin layer chromatography (TLC) and high-performance liquid chromatography-diode array detection (HPLC-DAD). The results revealed the presence of catechic tannins and approximately 17 phenolic compounds, including two compounds, which were identified for the first time in the date palm sub-product, especially in seeds such as naringenin and rutine.

STUDIES ON CHEMICAL COMPOSITION AND ANTIMICROBIAL ACTIVITIES OF BIOACTIVE MOLECULES FROM DATE PALM L.) POLLENS AND SEEDS.

Background: Natural resources have been the crucial origin of chemical elements. They have been used in many traditions as alternative medicines. The chemical profiling of some plant extracts and essential oils related to different plants were followed to unveil their most active components.

Identification and evaluation of antibacterial agents present in lipophilic fractions isolated from sub-products of Phoenix dactilyfera.

In this study, the dried powder of seeds and pollen of Phoenix dactylifera was extracted using Soxhlet extractor and biochemical composition of lipophilic extracts was analysed by GCMS. Then, we have tested the antibacterial effect of fatty acids and volatile compounds found in these sub-products. The results revealed that the main fatty acids found in Deglet Nour seeds is are oleic acid (42.
