Content Determination of Total Alkaloids in Cultivated BulBus Fritillariae Cirrhosae by Spectrophotograhpy
2010
OBJECTIVE:To establish the method for the determination of total alkaloid in cultivated BulBus Fritillariae Cirrhosae. METHODS:Spectrophotography was used to determine the content of total alkaloids with kashmirine as control,bromocresol green as colored indicator at detection wavelength of 416 nm. RESULTS:The linear range of kashmirine were 4.5~14.5 μg·mL-1 (r=0.999 6) with an average recovery of 98.76%(RSD=2.5%,n=6).CONCLUSION:The method is simple,accurate and relia-ble for the quality control of cultivated BulBus Fritillariae Cirrhosae.
