Abstract: The inherent natural antioxidants found in numerous medicinal plants (MPs) play a crucial role in counteracting the detrimental impacts of oxidative stress.MPs contains polyphenols and flavonoids, which serve as scavengers for free radicals, mitigating oxidative stress and offering potential as alternative treatments for a range of human ailments.The significance of this study lies in its chromatog. spectrum identification, providing a in-depth exploration of the antioxidant capacities and toxicol. profiles within the genetic resources of Argyrolobium arabicum.This study described the chromatog., spectroscopic, antioxidant and hepatoprotective actions of A. arabicum leaves collected from arid zones of Saudi Arabia.Argyrolobium arabicum chromatog. separations of bioactive compounds (HPLC detection isolate prominent compounds D-Pinitol and vitexin) and GC-MS spectra identified five phenolics and six flavonoids organic compoundsFT-IR spectroscopy revealed prominent functional group of alcs. and carboxylic acids bonds stretching.The hepatic toxicity and protective effects were notably administrated of A. arabicum extracts at a dosage of 300 mg/kg, leading to the restoration of ALT levels to 51 (U/L), AST levels to 71.6 (U/L), ALP levels to 169 U/L, and total bilirubin levels to 0.58 (g/dL), which had been altered by the neg. control.This research basically contributing to the understanding of medicinally important A. arabicum potential applications in pharmaceutical and environmental fields and used as to elucidate the complex genomic mechanisms explaining the bioactivity and safety of medicinal species.

The brown marmorated stink bug Halyomorpha halys, an invasive species native to East Asia, is now present and abundant on soybean throughout Europe where it has become a major pest damaging the crop.Because a better understanding of the impact of H. halys is crucial to implement effective and sustainable pest management, the present study aimed to assess the stages at which soybean is most susceptible to H. halys attacks, and the qual. and quant. alterations caused by its feeding on soybean seeds.Therefore, soybean plants were exposed to stink bug adults for 2 wk at different development stages and were examined at harvest for damage.Stay-green syndrome occurred most severely as a result of H. halys attacks at soybean development stages R4-R5.In the same period, the bug feeding activity significantly reduced the number of seeds per pod, thus indicating a higher damage rate at the R4-R5 stage when soybean surveillance should be intensified in order to properly target pest management strategies.The lower number of seeds per pod corresponded to an increase in the seed weight due to plant compensation mechanisms, leading to grain yields that did not differ in relation to the time of attack or the rate of damaged seeds.However, while not causing overall a loss of weight production, H. halys attacks were shown to cause qual. damage to soybean seeds, especially by altering protein content and mobilizing several primary metabolites from storage macromols., which will have to be considered depending on the intended use of the production
