Computational study of antocyanin compounds (Cyanidin and Petunidin) supported on TiO2 for DSSC application potential

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract This research predicts electronic properties (HOMO ILUMO energy diagram, UV-Vis spectrum, and the density of the HOMO / LUMO orbital) of cyanidin and petunidin organic dye compounds supported by TiO2. This system is modelled by interacting dyestuff compounds with the simplest TiO2 units to predict the effect of these dyes so ...

Enzymatic Synthesis of [3‘-O-Methyl-3H]malvidin-3-glucoside from Petunidin-3-glucoside [PDF]

open access: yesJournal of Agricultural and Food Chemistry, 2002
Malvidin-3-glucoside has been labeled by enzymatic synthesis in a single-step experiment. Catechol-O-methyl transferase catalyzed the B-ring methylation of petunidin-3-glucoside, and S-Adenosyl-L-[methyl-(3)H] methionine was the methyl donor. Solid phase extraction and preparative high-performance liquid chromatography were necessary to separate [3'-O ...
