Abstract
This study aimed to introduce a novel approach named Vector Operation Moving Block Standard Deviation (VO-MBSD) to characterize the original powder blend uniformity of Angong Nuihuang intermediate using NIR technology, including 400g Rhizoma Coptidis, 400g Radix Scutellariae, 400g Radix Curcumae and 400g Fructus Gardeniae. A novel blending evaluation method named VO-MBSD compared with Moving Block Standard Deviation (MBSD) was applied to characterize the blending of Chinese Materia Medica (CMM) original powder including Rhizoma Coptidis, Radix Scutellariae, Radix Curcumae and Fructus Gardeniae. HPLC (High Performance Liquid Chromatography) analysis demonstrated these observations perfectly. OV-MBSD is the rate of change by time, which not only represents the scalar change but also the vector change. The identification accuracy of blend uniformity and end-point via VO-MBSD was the same with classical HPLC method. This method is more accuracy than original MBSD method. Compared with classical MBSD, it is appropriate for the determination of blending end-point and could be successfully implemented as an on-line monitoring tool for blending process.
