ABSTRACT
OBJECTIVE: To establish methods for the identification of Rhizoma Chuanxiong and determination of Ferulic acid( FA) in Ganning granula. METHODS: The identification of Rhizoma Chuanxiong was carried out by TLC and the determination of FA was by performed by HPLC. FA was separated on Kromasil ODS-1 C18 column with water-methanol-acetic acid ( 30∶ 69. 5∶ 0. 5) as mobile phase. The detection wavelength was 322nm, the column temperature was set at room temperature and the flow rate was 1. 0mL? min-1. RESULTS: The TLC spots of the sample presented the same color as its counterparts of Rhizoma Chuanxiong standard and FA reference substance at the corresponding sites. The linear range of FA was 0. 010 12 ～ 0. 151 80? g( r=0. 999 9, n=8) . The average recovery was 97. 39% ( RSD=1. 97% ) . CONCLUSION: The methods of identification and content determination were rapid, accurate, specific and reproducible, and which are suitable for the quality control of Ganning granula.
ABSTRACT
Aim To observe the action of hydroxyanthroquinones from Rheum Palmatum L on reduced jaundice and enzyme in acute jaundice model of rat induced by ANIT.Methods Wistar rats were randomized into five groups: group A in which no treatment was given,group B in which ANIT was given on the eighth day,group C in which high dosage of hydroxyanthroquinones from Rheum Palmatum L was given,group D in which low dosage of hydroxyanthroquinones from Rheum Palmatum L was given,group E in which "Yinzhihuang injection" was given as positive control.Except group A and B,other groups were given corresponding drugs for 7 days and then additionally administered ANIT to induce jaundice on the eighth day.Forty-eight hours later,the rats′ blood was gained from eyes and the serum was separated.The liver functional sign,the activity of SOD,the content of MDA in serum and change in pathology of liver tissue were observed.Results Compared to group B,ALT,AST,TBIL,ALP,?-GT ,MDA of group C and E descended obviously(P0.05).Conclusion Hydroxyanthroquinones from Rheum Palmatum L has the action of reducing serum bilirubin and transaminase and improving liver tissue injury in rats of experimental Cholestasis.
ABSTRACT
Hyodeoxycholic acid in Calculus Bovis Antidote tablet was determined quantitatively by dual wavelength TLC scaning. The experiment was carried out on silica gel-G plates with chloroform -ether-glacial acetic acid (2:2:1) as the mobile phase, and ethanol solution of phosphomolybdic acid (10% ) as developer, at ?s=700nm,?R= 450nm. Recovery was 103. 4% and RSD=3. 2% (n=5 ). This method is accurate and convenient It can also be used for quantitative analysis of other preparations containing hyodeoxycholic acid
ABSTRACT
AIM:To determine Radix et Rhizoma Rhici in Ganning Granula(Radix et Rhizoma Rhei,Rhizoma Chuanxiong). METHODS: In order to determine five anthraquinone aglycones of Radix et Rhizoma Rhei,the HPLC system consisted of Nucleosil ODS column,methand-0.1% phosphoric acid(85∶15) mixture as mobile phase,with detection wavelength at 430 nm. RESULTS: HPLC showed that the linearity ranges were as follows: aloe-emodin concentration was at the range of 0.041 6-0.291 2 ?g,the rhein concentration was at the range of 0.037 1-0.259 8 ?g,the emodin concentration was at the range of 0.045 8-0.320 3 ?g,the chrysophanol concentration was at the range of 0.049 60.347 2 ?g,the physcion concentration was at the range of 0.020 6-0.144 5 ?g.The average recoveries of five anthraquinone aglycones were between 96.6%-98.4%.CONCLUSION: The method is simple,accurate,sensible and with good repeatability and can be used for quality control of Ganning Granule.
