Isolation of Antidiabetic Principle from Fruit Rinds of Punica granatum
Present study was aimed to isolate and evaluate the antidiabetic activity of phytoconstituents from fruit rinds of Punica granatum. With the above objectives Valoneic acid dilactone (VAD) was isolated from methanolic fruit rind extracts of Punica granatum (MEPG) and confirmed by (1)H-NMR, (13)C-NMR, and mass spectral data. Antidiabetic activity was evaluated by Aldose reductase, α-amylase and P...
متن کاملNew sterol esters from the flowers of Punica granatum Linn.
Two new beta-sitosterol esters have been isolated from the flowers of Punica granatum Linn. (Punicaceae) along with the known compounds n-tricosane (3), n-heptacosanyl n-hexanoate (4), olean-5,12-dien-3beta-ol-28-oic acid (5), and olean-12-en-3beta-ol-28-oic acid (6). The structures of the new phytosterols have been elucidated as stigmast-5-en-3beta-ol-3beta-dodecanoate (beta-sitosterol laurate...
متن کاملPhotocatalytic Conversion of Nitrobenzene to Aniline through Sequential Proton-Coupled One-Electron Transfers from a Cadmium Sulfide Quantum Dot.
This paper describes the use of cadmium sulfide quantum dots (CdS QDs) as visible-light photocatalysts for the reduction of nitrobenzene to aniline through six sequential photoinduced, proton-coupled electron transfers. At pH 3.6-4.3, the internal quantum yield of photons-to-reducing electrons is 37.1% over 54 h of illumination, with no apparent decrease in catalyst activity. Monitoring of the ...
