摘要： A process is provided for making (−)-epigallocatechin gallate (EGCG) by subjecting a green tea extract to chromatography on a macroporous polar resin, eluting EGCG from the resin with a polar elution solvent, optionally concentrating the eluate, optionally regenerating the resin by desorbing the remaining catechins, and optionally concentrating the desorbed catechins.

摘要： For activating a stepper motor, a pulse-width modulated current is supplied to a coil of the stepper motor and it is determined whether the current flowing through the stepper motor, based on a default value, lies within a current bandwidth defined by an upper switching threshold and a lower switching threshold. The current supply to the coil is switched on when the detected current has dropped to the lower threshold and is switched off when the detected current has risen to the upper threshold. In order to detect a step loss, the signal form of the current or its change, respectively, is analyzed and deviations from desired values or desired value ranges, respectively, which have been caused by step losses, are detected. The determination of the signal form of the current or its change, respectively, may occur indirectly by analyzing a corresponding control signal.
