Optimization of the extraction procedure for the ...

2020-1-5  In most cases, the concentrations of phenolic compounds and the values for TPC and ORAC were significantly higher in extracts produced from material which was prepared by ball mill compared to a coffee grinder, irrespective of the extraction procedure . In addition, using a ball mill instead of a coffee grinder notably improved the reproducibility of all extraction procedures.

Effect of extraction procedure on the molecular

Wheat straw was treated with sodium hydroxide at various conditions, or ball-milled for 4, 8, 16, and 144 h in a porcelain rotary ball-mill and sequentially hydrolyzed by a cellulase for 3 days, and it was delignified by ethanol/water mixture (60:40, v v) with 0.02 N H 2 SO 4 as a catalyst at 75 °C for 1, 1.5, 2, 2.5, 3, 5 and 12 h, respectively. The alkali lignin fractions (LA) were isolated by two step precipitation.

Fast sample preparation for analysis of tablets and ...

The ball-mill sample preparation procedure is both quantitative and fast. No powdering, weighing and sonication steps are needed in the sample preparation. The complete procedure takes 2 min (milling and extraction) and 5 min (centrifugation), respectively, much less than the conventional method in which sample preparation takes approximately 45–90 min.
