TL;DR: In this paper, the authors aimed to optimize the extraction of phenolic compounds from grape marc, investigating extraction kinetics (from 1 to 24 h) at 45 and 60 °C, and the effect of solvent (ethanol with different water content) on phenols yield and quality of extracts (phenols concentration and antioxidant power).

TL;DR: The efficiency of pigment extraction forms the crux of the spectrophotometric analysis of chlorophyll a and the alcoholic solvents, methanol and ethanol, proved to be superior to acetone and acetone with DMSO.
Abstract: The efficiency of pigment extraction forms the crux of the spectrophotometric analysis of chlorophyll a. The alcoholic solvents, methanol and ethanol, proved to be superior to acetone and acetone with DMSO. Homogenisation and sonication did not improve the extraction in the alcoholic solvents. Boiling at 100°C had an adverse effect whereas complete extraction of the pigments was obtained at the solvents boiling point and allowing the samples to stand for 24 h in the dark.

TL;DR: In this article, the use of total lipid phosphate as a measure of biomass was evaluated in soils with different organic matter content, and the two digestion methods showed a good linear correlation (r2 = 0.991).
