This study was conducted to isolate and identify the bioactive compounds from the ethanolic extract of leaf against species through a bioassay-guided fractionation. The ethanol extract was exposed to silica gel chromatography followed by reversed phase HPLC to isolate the most effective fraction against . Using further UHPLC-orbitrap-ion trap mass spectrometry, five compounds were isolated with broad-spectrum potency against a range of Vibrio species viz. and The IC values for the compounds ranged from 8 to 48 µg/mL against the most sensitive species and 58 to >400 µg/mL against The results of the toxicity tests demonstrated that the compounds were not harmful for shrimp. The study's findings indicate that leaf extract may contain bioactive molecules that are able to be substituted for antibiotics to treat vibriosis in shrimp farming.

Secondary metabolites are important bioactive compounds for diet and medicine. This study optimizes the extraction of hydroethanolic herbal extracts using an EDGE (Energized Dispersive Guided Extraction) system, evaluates their antioxidant capacity, and analyzes correlations among antioxidant activity, total phenolic content, and individual compounds. A Doehlert matrix design was used to optimize extraction, having temperature and time as independent variables, and total phenolic content (mg GAE/g) as the response, quantified via the Folin-Ciocalteu method.

Synthetic dyes, such as Congo red (CR), pose serious threats to human health and aquatic ecosystems because of their carcinogenicity and resistance to degradation, necessitating the development of efficient and eco-friendly remediation strategies. In this study, silver nanoparticles (AgNPs) were synthesized via a green method using Ocimum sanctum (holy basil) leaf extract and applied for CR dye removal from aqueous solutions. The adsorption process was optimized using response surface methodology (RSM) based on Box-Behnken design (BBD), evaluating the influence of key parameters including pH, AgNP dosage, initial dye concentration, contact time, and temperature.

In the present study, eight undescribed compounds, namely caseazins R-Y (1-8) were isolated from the twigs and leaves of Casearia kurzii (Flacourtiaceae). Their structures were elucidated by extensive spectroscopic analysis, nuclear magnetic resonance methods, X-ray diffraction analysis, and ECD calculations. Compound 1 was characterized as a rare 2,3-seco podocarpane carbon skeleton.
