L., a medicinal plant rich in secondary metabolites, was studied for optimising bioactive compound extraction from various parts of the plant using ethanol-water (50:50), ethanol, and methanol solvents. Analysis of extracts for key phytochemicals like polyphenols, flavonoids, saponins, and alkaloids was performed using HPTLC, HPLC and gas chromatography. The ethanol-water mixture proved best for extracting saponins and polyphenols, ethanol for flavonoids, and methanol for alkaloids. The fruit yielded the highest saponin content (59.34% ± 3.87), while leaves were richest in polyphenols (18.94% ± 1.39), flavonoids (5.15% ± 1.01), and alkaloids (26.46% ± 1.71). Leaf extracts showed the highest antibacterial activity against and , and stem extracts were effective against . Root, stem, and leaf extracts exhibited antifungal activity with leaf extract also demonstrating strong phytoestrogenic activity. These findings highlight the varied phytochemical profiles and biological activities of , suggesting their potential therapeutic uses.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

To address this problem, an ensemble multi-dimensional randomization network (EMRNet) for intelligent recognition of tobacco baking stage is proposed. The first is to obtain the tobacco leaf area during the baking process.

The efficient extraction and purification of active components from Eucommia ulmoides Oliver (EUO) are crucial for their utilization. The structure and properties of the prepared EUO leaf polysaccharides (ELPs) and extractum (ELE) were comprehensively characterized in this study, and the intervention mechanism of the EUO polysaccharides and extractum in alcoholic liver disease (ALD) were investigated. The yield of EUO extractum was 24.

Background: Ginkgo biloba leaf extract EGb 761® has shown clinical efficacy in patients with mild cognitive impairment and dementia. However, the pharmacological action of EGb 761® in Alzheimer's disease (AD) remains unclear and molecular mechanisms targeted in the brain are not completely understood.
Hypothesis/purpose: We aimed to investigate 1) the potential sex-dependent effects of oral administration of EGb 761® in 5xFAD mice, an AD mouse model, and 2) the underlying microglial subtype responsible for the observed anti-inflammatory effects in the brain.
