Mature seeds were ground with a ball mill (Retsch MM200, Vienna, Austria). The powder was suspended in anhydrous glycerol ( g mL −1). After addition of a small amount of quartz sand, the mixture was homogenized with a pestle. Cell debris and starch grains were removed by centrifugation for 5 min at 1,000g.
An important step in this direction was accomplished by the development of a motorised mortarandpestle setup by Retsch in 1923. 67 Automated ball mills designed for size reduction, such as tumbler mills (invented in 1870) and vibrational ball mills (invented in 1930), are also used for mechanochemical syntheses. 68
