ABSTRACT
AIM:To establish a quality standard for Anshen Wendan Pill(Rhizoma Pinelliae Praeparata,Pericarpium Citri reticulatae,Poria,Radix et Rhizoma Ginseng,etc.). METHODS:Pericarpium Citri Reticulatae,Fructus Schisandrae Chinensis,Radix et Rhizoma Ginseng,and Radix et Rhizoma Glycyrrhizae were identified by TLC,and the contents of schisandrin and hesperidin were determined by HPLC. The content of cinnabaris was determined by titration. RESULTS:Pericarpium Citri reticulatae,Fructus Schisandrae Chinensis,Radix et Rhizoma Ginseng,and Radix et Rhizoma Glycyrrhizae could be identified by TLC. The calibration curve of schisandrin was linear in the range of 0.017-0.52 ?g with the correlation coefficient of 1.000 0(n=5).The average recovery of schisandrin was 99.83%(RSD=0.86%,n=6). The calibration curve of hesperidin was linear in the range 0.506 -2.53 ?g,with the correlation coefficient of 1.000 0(n=5).The average recovery hesperidin was 100.43%(RSD=1.39%,n=6). The average recovery of cinnabaris was 98.30%(RSD=1.06%,n=6). CONCLUSION :The methods are simple,accurate and reproducible. They are suitable for the quality control of Anshen Wendan Pill.
ABSTRACT
AIM: To establish a gas chromatography method for the determination of sabinene in ledum terpenes from Ledum palustry L. METHODS: 5% SE 30 was adopted as the stationary phase, the temperature of column was set at 65 ?C and FID detector with termperature at 200 ?C . RESULTS: Sabinene in the preparation was gained satisfactory separation and assay under the chromatographic condition. The calibration curve of sabinene was good linear in the range of 0.06 0.60 mg?mL -1 . with the corelation coefficient r=0.9998(n=6) . The average recovery of sabinene was 100.3%, RSD=1.4%, (n=5) . CONCLUSION: The method is simple, highly repeatable and accurate, and it can be used to control the quality of the preparation.
