- W2390048130 abstract "Objective To establish the quality standards of Peganum harmala inCompound Muniziqi Granules. Methods Taking HAL and HAR as control,to establish the quality standards of P. harmala inCompound Muniziqi Granulesby thin-layer chromatography( TLC) and HPLC. The TLC method was developed by using mixture of ethyl acetate-methanol-ammonia( 10∶ 1. 5∶ 0. 5) as a developing solvent on high performance silica gel precoated plate( HSGF254). In the HPLC method,HAL and HAR was separated on a reverse phase HPLC chromatographic column with acetonitrile-ammonium acetate( 22∶ 78) as the mobile phase with flow rate of 1. 0 ml / min,column temperature was maintained at 30℃ and the wave length was detected at 330 nm. Results The reslutes of HPLC showed that HAL and HAR displayed ideal linearity within the ranges of 0. 33 ~ 104. 10 and 0. 13 ~ 40. 91 mg / L. The average recoveries of HAL and HAR were 97. 04%and 101. 83% with RSD of 2. 02% and 2. 32%,respectively. The RSD values of intra-day and inter-day precision were less than 3%. The content of HAL in 15batchesCompound Muniziqi Granulesfluctuates between 1. 62 ~ 5. 04 mg and HAR between 0. 87 and 2. 22 mg of each bag,the total alkali between 2. 49 ~7. 14 mg of each bag. Conclusion The method was sensitive,accurate,reproducible,and it can be used to determine and control the quality of seeds of P.harmala inCompound Muniziqi Granules." @default.
