Green synthesis methods for producing nanoparticles have been explored due to the increasing demand for environmentally friendly and sustainable approaches in nanotechnology. In this work, Tageteserecta (Marigold) flower extract is used to synthesize and characterize iron nanoparticles (FeNPs), It serves as a stabilizing and reducing agent naturally. Traditional chemical methods often involve toxic reagents and energy intensive processes, which pose health and environmental risks. In contrast, the phytochemicals found in Marigold, such as flavonoids, phenols, and terpenoids, allow the reduction of Fe³⁺ ions to Fe⁰ nanoparticles under mild conditions. The synthesis was conducted by reacting an aqueous solution of ferric chloride (FeCl₃) with Marigold extract, optimizing parameters like temperature (60–80°C), time (2–4 hours), pH, and feed ratio (1:1 to 1:3).A number of characterization methods such as UV-Vis spectroscopy (absorption peak around 280–320 nm), FTIR (identifying functional groups responsible for reduction and capping),SEM/Edax (revealing spherical morphology and size) and were used to confirm the formation of FeNPs.The resulting nanoparticles ranged in size and stability from 20 to 50 nm , were impacted by the synthesis circumstances. This green synthesis approach demonstrates an efficient, low-cost, and ecologically benign route for iron nanoparticle manufacturing, contributing to sustainable nanotechnology practices and the valorization of floral biomass waste.

Degradation, mobilization nutrient, mineralization, solubilization, nitrogen fixation, and growth hormone synthesis are among the soil processes that are mediated Via (PGPR). As result developing organic acids, microorganisms with the ability to solubilize phosphates can change insoluble phosphates into soluble forms. Phosphorus deficit may be mitigated by the promising method of inoculating seeds with P-solubilizing bacteria. The availability From the soil Soil phosphorus around roots differs substantially based Upon the plantspecies and soil nutrition. Derived from 251 bacterial isolates were Extracted Starting at the roots of three different plants Legumes such as chickpeas, lentils, and beans grown in Kirkuk, Erbil .In overall, there were (128)isolates Associated with plant growth-promoting rhizobacteria in Kirkuk &123) isolates in Erbil (though only 54 of these isolates Evaluated for different plant growth-promoting traits were selected and detected. A total of 54 isolates were investigated In vitro phosphate solubilization by these isolates in legumes. According to Bergey’s Manual, the overall percentages of isolates were Pseudomonas spp (34%), Enterobacter spp (31%), Legionella beijerinckiaspp (10%), Bacillus spp (8%), Nitrobacterspp (8%), Nitrosomonasspp (3%), Paenibacillus (3%), Actinomycetes (1%), Frankia (1%), Mycxobacteriaspp (1%), Closttridumspp (1%), Actinobacillus (1%).

In Vitro Evaluation of Alpha-Amylase Inhibitory Activity of Ethanolic Leaf Extracts of Aegle marmelos and Turnera ulmifolia

Aegle marmelos (Bael), a medicinal plant widely used in traditional Ayurvedic medicine, has shown promising antidiabetic, antioxidant, and hepatoprotective effects. Their leaves contain many bioactive constituents such as flavonoids, tannins, alkaloids, and coumarins, contributing to their therapeutic potential. Similarly, Turnera ulmifolia, commonly known as yellow alder, is an ethnomedicinal plant exhibiting antihyperglycemic, antioxidant, and anti-inflammatory activities. This study investigates the in vitro α-amylase inhibitory potential of ethanolic leaf extracts of Aegle marmelos and Turnera ulmifolia. The extracts were prepared by cold maceration and assessed using the DNS assay. Among the tested samples, Aegle marmelos demonstrated notable inhibitory activity, while Turnera ulmifolia showed minimal effect. These findings support the traditional use of Aegle marmelos in diabetes management and highlight the need for further studies to isolate active constituents and evaluate their in vivo efficacy.
