Article Title: Optimizing ultrasonication-assisted comprehensive extraction of bioactive flavonoids from Pterocarpus santalinus leaves using response surface methodology.
Article Snippet: The leaves of Pterocarpus santalinus have been identified as a good source of health-beneficial flavonoids through the amalgamation of untargeted metabolomics using UHPLC-ESI-MSn leading to the identification of flavoneglycosides bearing isorhamnetin and quercetin skeletons.. To unveil the optimum ultrasonication extraction conditions required for the comprehensive extraction of major flavone-glycosides, isorhamnetin-3-O-β-d-(2-Oα-L-rhamnopyranosyl)glucopyranoside and isorhamnetin-3-O-β-d-glucopyranoside, the response surface methodology based on Box-Behnken design was adopted.. The influence of input extraction parameters extraction time (X1): 15–45 min, temperature (X2): 40–60 C and biomass-solvent ratio (X3): 60–100 on the extractive yield and comprehensive flavonoid content resulted in the optimal conditions as 19.09 min, 48.65 oC, and 72.15, respectively.

Article Title: Distribution of carcinogenic polycyclic aromatic hydrocarbons in urban soil across major cities of Bihar, India: seasonal variation, source apportionment, and health risk assessment.
Article Snippet: This study investigates the distribution of sixteen priority polycyclic aromatic hydrocarbons (PAHs), various sources of PAHs, and their probable cancer-causing risks in the soil samples collected from urban cities in Bihar, India.. During the winter season, the ∑16 PAH concentration was dominant and ranged from 979.36 to 5149.37 ngg−1 with a mean value of 2684.79 ngg−1, while for the summer season, it ranged from 690.06 to 4539.55 ngg−1 with a mean value of 2194.31 ngg−1.. The (4-ring) PAH compounds were the major contributors, accounting for 40% and 37% in the winter and summer seasons, respectively followed by (5and 6-ring) PAHs at 30% and 32%, and (2and 3-ring) PAHs at 29% and 30% in the respective seasons.
