Article Abstract
The young leaves of Vernonia amygdalina are often utilized as vegetable and for medicinal purpose compared to the old leaves. This study was designed to evaluate and compare the antidiabetic effects between ethanolic leaf extracts of old and young V. amygdalina on streptozotocin (STZ) induced diabetic rat for four weeks. Preliminary screening of both young and old ethanolic extracts revealed the presence of the same phytochemicals except flavonoids which was only present in the old V. amygdalina. Difference in antioxidant power between the young and old leaf extracts was statistically significant (p < 0.05). Both leaf extracts produced a significant (p < 0.05) antihyperglycaemic effect. Also results from treated rats revealed increasing effect in some haematological parameters. Similarly, the higher dose (300 mg/kg) of both extracts significantly (p < 0.05) reduced serum ALT, AST, and ALP levels as compared to the diabetic control rats. Results also showed significant (p < 0.05) decrease in LDL-C and VLDL-C in the extract-treated rats with a corresponding increase in HDL-C, as compared to the diabetic control rats. Moreover histopathological analysis revealed ameliorative effect of pathological insults induced by the STZ in the pancreas, liver, and spleen, most significantly the regeneration of the beta cells of the islets of Langerhans in treated rats.
(Family: Fabaceae) is traditionally used in Ayurvedic medicine for various medicinal purposes, including as a treatment for wounds, leprosy, skin diseases, fever, diabetes, etc. Although the root and stem of this plant have a significant medicinal value, there was little research on the leaves of this plant. This study aimed to investigate the qualitative phytochemical profile and evaluate the in vitro cytotoxic, anti-inflammatory, antioxidant, and antiarthritic activities, as well as the in vivo anti-inflammatory and analgesic activities, of leaf extract.

The production of nanoparticles via green methods is a developing study domain due to potential environmental applications. The green synthesis method is very easy, less toxic and eco-friendly when compared to the chemical synthesis method. This study addresses the silver nanoparticle synthesis utilizing the Acorus calamus leaf extract, which was then employed for environmental applications.
Metal nanoparticles have attained much popularity due to their low toxicity, economic feasibility, and eco-friendly nature. The present study focuses on the synthesis of silver and zinc nanoparticles from Vitex altissima leaf extract, further characterized by UV/Vis spectral analysis, Powder-XRD, FE-SEM, FTIR, TEM, DLS, and Zeta potential. Synthesized silver and zinc nanoparticles were screened for anti-oxidant, anti-inflammatory, anti-bacterial, and anti-biofilm activities.
Physalis alkekengi L. is recognized as a significant source of various secondary metabolites, particularly c28 steroidal lactones known as withanolides and physalins, renowned for their therapeutic properties with a rich history in traditional medicine. In this study, we characterized the sequences of key downstream genes (PaFPPS, PaSQS, PaSQE, PaCAS, PaHYD1, and PaDWF5-1) involved in the biosynthesis of withanolides, marking the first characterization of these genes in P.
Sesame (Sesamum indicum L.) is an important oilseed crop, and its seeds are a source of edible oil and widely used as a nutritious food that is beneficial to health in oriental countries. Phytochemical and biological investigations of the seeds have been well reported; however, those of the leaves have been limited.
