Kinetics, Thermodynamics, and Solvent Polarity Effects of Ultrasound‑Negative Pressure Cavitation Fractional Precipitation of (+)‑Dihydromyricetin

Abstract
In this study, the effect of precipitation solvent polarity during ultrasound-negative pressure cavitation methanol–water fractional
precipitation was investigated to effectively purify (+)-dihydromyricetin from biomass. The optimal solvent conditions
were selected by changing the solvent polarity and the precipitation temperature. Additionally, kinetic and thermodynamic
analyses of the precipitation process were conducted. The highest yield (96.87%) and purity (92.35%) of (+)-dihydromyricetin
were obtained at a polarity index of 9.51. Furthermore, the diffusion coefficient and rate constant reached maximum
values of 8.89 × 10−10cm2∕s and 0.85, respectively. Impurities in the sample were selectively removed via the polarity of
the precipitation solvent. The thermodynamic parameters revealed that the precipitation was exothermic, irreversible, and
non-spontaneous.
