A novel scaffold for effective wound healing treatment was developed utilizing natural product bearing collagen-based biocompatible electrospun nanofibers. Initially, ostholamide (OSA) synthesized from osthole (a coumarin), characterized by 1H, 13C, DEPT-135 NMR, ESI-MS, and FT-IR spectroscopy analysis. OSA incorporated into polyhydroxybutyrate (PHB) gelatin (GEL), which serve as templates The coating of OSA-PHB-GEL nanofibers with collagen resulted in PHB-GEL-OSA-COL nanofibrous mimics...

The present study was carried to evaluate the effect of size reduction using ultrasonication on functionality and bioactivity whey protein isolate (WPI). results showed that able reduce particle from 1.025 µm 549 nm. polydispersity index zeta potential increased subsequently upon 0.22 0.48 -12 -21 mV confirming narrow range distribution enhanced colloidal stability. SEM non-treated dense spherical structure whereas granules changes polygon. Size granule reduced distortion in shape observed....

The urea oxidation reaction (UOR) and methanol (MOR) are the most practical alternative counter-reactions to hydrogen evolution in overall electrochemical water splitting process. thermodynamic gains terms of lower water-splitting potentials compared oxygen (OER) can be cashed if kinetics UOR MOR suitably controlled. This has called for development suitable cost-effective non-precious catalysts processes. Herein, we report synthesis a heterostructured composite catalyst that incorporates...

Phytochemical analysis of the dichloromethane:methanol (1:1) extract root parts Prangos pabularia led to isolation twelve cytotoxic constituents, viz., 6-hydroxycoumarin (1), 7-hydroxycoumarin (2), heraclenol-glycoside (3), xanthotoxol (4), heraclenol (5), oxypeucedanin hydrate (6), 8-((3,3-dimethyloxiran-2-yl)methyl)-7-methoxy-2H-chromen-2-one (7), monoacetate (8), xanthotoxin (9), 4-((2-hydroxy-3-methylbut-3-en-1-yl)oxy)-7H-furo[3,2-g]chromen-7-one (10), imperatorin (11) and osthol (12)....

Abstract Diosgenin, a steroid saponin in various plant species, has been described as promising bioactive biomolecule with wide range of significant therapeutic benefits, including antibacterial, hypoglycemic, antioxidant, and hypolipidemic effects. A different unique synthesis method is demonstrated this research article to get better high‐yield products. All the 12 synthesized compounds were well‐characterized by FTIR, 1 HNMR, 13 CNMR, HRMS. Post characterization, all evaluated for...

Abstract The valorization of new polymer sources from underutilized plants as structuring, encapsulating, and texturizing agents for food nutraceutical applications is gaining attention. This provides an opportunity where inexpensive plant-sourced biopolymers can play impactful role, on both ecological economic aspects performing equivalently effectual yet cost-effective substitutes to synthetic polymers. With this aim, we explored the use mucilage Althea rosea reveal its physicochemical, in...

In the current study, leaf volatile constituents of essential oils Artemisia indica Willd. and vestita Wall were studied using a combination capillary GC–FID, GC–MS FT-IR (Fourier-Transform Infra-Red) analytical techniques. The analysis led to identification 42 compounds in oil A. indica, representing 96.6% major components found be artemisia ketone (42.1%), germacrene D (8.6%), borneol (6.1%) cis-chrysanthenyl acetate (4.8%). was dominated by presence oxygenated monoterpenes constituting...

This work was carried out to evaluate chemical composition, antibacterial, antioxidant and anticancer activity of Pinus roxburghii essential oil. The oil extracted by hydro-distillation which analysed through GC-MS. antibacterial evaluated agar well diffusion method DPPH assay while as MTT method. Alpha-pinene beta-pinene were the major constituents present in showed significant activity.

Oxypeucedanin hydrate monoacetate (Mol. Formula = C18H18O7) micro-crystals were obtained by acetylation of oxy-peucedanin hydrate, a furanocoumarin, isolated from the roots Prangos pabularia. The composition related structural, thermal and optical properties investigated. All crystals found to have triclinic structure. From studies these crystals, stability, melting point other relevant informations obtained. Their blue emission, less absorption in entire visible range band gap predicts as...

The essential oil composition of the leaves Artemisia absinthium, growing in Kashmir, India, along with its antioxidant activity, is reported present study. Gas chromatography coupled mass spectrometry (GC-MS) revealed presence twelve constituents, representing 99.99% total oil. major constituents were Chrysanthenyl acetate (49.15%) and L-β-pinene (39.62%). monoterpene content was found to be 98.76 %, while as sesquiterpene hydrocarbon 1.23%. evaluated for activity DPPH radical, exhibiting...

AbstractPlant-isolated compounds, Osthol [7-methoxy-8-(3-methylbut-2-enyl) coumarin], were subjected to modification in the isopentenyl side chain get an aldehyde of 2-methyl-4 (7-methoxy-2-oxo-2H-chromen-8-yl)-but-2-en-1-al. This modified compound was exposed γ-radiation produced by 137Cs source at room temperature. Pre- and post-irradiation study carried out ultraviolet–visible spectroscopy. The shows a sharp absorption peak 322 nm. observed band decreases with irradiation up certain dose...
