The current research focused on the green synthesis of silver nanoparticles (AgNPs) using Duabanga grandiflora leaf extract. The green synthesis of AgNPs was confirmed by the surface plasmon resonance band at 453 nm in a UV-Visible analysis. The formulated AgNPs had a diameter of around 99.

- Silver nanoparticles (Ag NPs) were synthesized using Osbeckia stellata leaves, highlighting the benefits of an eco-friendly and cost-effective approach through green synthesis.
- Characterization techniques such as UV-Vis spectroscopy and SEM showed that the Ag NPs have a spherical shape and are in the nanometer size range, confirming their effective biosynthesis.
- The study found that these Ag NPs demonstrate strong antioxidant, antidiabetic, cytotoxic, and antimicrobial properties, indicating their potential applications in biomedical and pharmacological fields.
A mild and eco-friendly visible-light-induced synthesis of 2-(2-hydrazinyl) thiazole from readily accessible thiosemicarbazide, carbonyl, and phenacyl bromide in the absence of a metal catalyst and/or any extrinsic photosensitizer is reported. This approach only requires a source of visible light and a green solvent at room temperature to produce the medicinally privileged scaffolds of hydrazinyl-thiazole derivatives in good to outstanding yields. Experimental studies support the formation of a visible-light-absorbing, photosensitized colored ternary EDA complex.

- Different parts of tea were extracted using solvents of varying polarity to examine their phytochemical profiles and biological activities.
- The study found that as the polarity of the solvents increased, the total phenolic and flavonoid contents also increased, with the most effective extracts coming from polar solvents like hydroalcohol.
- Strong correlations were observed between the phytochemical contents and the biological activities, indicating that phenolic compounds in tea, especially from young leaves, are effective antioxidants, anti-inflammatory, and antidiabetic agents.
Article Synopsis
- α-Amylase inhibitors derived from natural sources like Asparagus racemosus show potential for developing new diabetes treatments, with improved methods for isolating bioactive compounds using advanced techniques like HPTLC combined with spectroscopy.
- The study utilized different solvent extractions of the plant's aerial parts and performed assays to identify antioxidant activity and α-amylase inhibition, finding that the methanolic extract had the highest antioxidant effectiveness.
- The research concluded that stigmasterol, identified through analytical methods, is likely responsible for the observed α-amylase inhibition, supporting A. racemosus's traditional medicinal use for diabetes management.
