Phytochemistry Studies

Phytochemical and functional characterization of cultivated varieties of Morus alba L. fruits grown in Italy.

A study on Morus alba cultivars in Italy found variations in nutritional value and biological activity. Some compounds correlated strongly with activity, and levels decreased as fruits ripened, impacting consumption and economic value.

Titanium dioxide nanoparticles improve element uptake, antioxidant properties, and essential oil productivity of Melissa officinalis L. seedlings under in vitro drought stress.

This study investigated how titanium dioxide nanoparticles (TiO NPs) can improve the physiological responses and phytochemical properties of Melissa officinalis (medicinal plant) under drought stress. The results showed that TiO NPs increased essential oil production, photosynthetic pigments, antioxidant systems, nutrient absorption, and reduced stress levels.

Inhibitory effects of Jasminum grandiflorum L. essential oil on lipopolysaccharide-induced microglia activation-integrated characteristic analysis of volatile compounds, network pharmacology, and BV-2 cell.

This study analyzes the volatile compounds in L. flowers and evaluates the inhibitory effects of L. essential oil on microglia activation. The findings suggest that L. essential oil can inhibit overactivation of microglia, reducing neuroinflammation and oxidative stress responses in Alzheimer's disease.

Adaptive response of flavonoids in Robinia pseudoacacia L. affected by the contamination of cadmium and elevated CO(2) to arbuscular mycorrhizal symbiosis.

Arbuscular mycorrhizal fungi (AMF) reduce cadmium (Cd) content in leaves under elevated CO. However, AMF colonization decreases flavonoid synthesis in the presence of Cd and elevated CO, affecting plant defenses against abiotic stress.

Panax quinquefolius saponins combined with dual antiplatelet therapy enhanced platelet inhibition with alleviated gastric injury via regulating eicosanoids metabolism.

Panax quinquefolius saponin (PQS) combined with dual antiplatelet therapy (DAPT) was studied for its effects on platelet aggregation, heart attack expansion, gastric injury in rats, and its impact on arachidonic acid metabolism. PQS showed potential benefits.
