ABSTRACT
OBJECTIVE To establish methods to identify the chemical components of Gantaishu capsule， and determine the contents of 6 index components including glycyrrhizic acid. METHODS The chemical components of Gantaishu capsule were determined by HPLC-TOF/MS； the contents of 6 index components including glycyrrhizic acid were determined by UPLC-MS/MS. RESULTS A total of 41 chemical components were identified in Gantaishu capsules. The linear ranges of glycyrrhizic acid， mangiferin， luteolin， costunolide， oleanolic acid and berberine were 200-10 000 ng/mL（r were all greater than 0.999）. The limits of quantification were 200， 20， 10， 1， 10， 0.5 ng/mL， and the limits of detection were 100， 10， 5， 0.5， 5， 0.25 ng/mL， respectively； RSDs of precision， stability （24 h） and reproducibility tests were all less than 5.0% （n＝6 or n＝3）； the recoveries were 99.05%-101.08% （RSD were all less than 2.0%， n＝6）. The contents of them were 2.42-2.66， 0.85-1.16， 0.35-0.46， 6.18- 6.46， 0.99-1.29， 5.22-5.56 mg/g. CONCLUSIONS The established methods for identification and content determination are rapid and simple， and can be used for the identification of chemical components and the content determination of index components in Gantaishu capsule.
ABSTRACT
To evaluate the efficacy and safety of Gantaishu Capsules in the treatment of viral B hepatitis. The randomized controlled trials( RCT) retrieved from Cochrane Library,PubMed,Sino Med,CNKI,Wan Fang and VIP were enrolled. The methodology quality of the included studies was evaluated,and a Meta-analysis was performed using Rev Man 5. 3 software. A total of six randomized controlled trials were included. Meta-analysis results showed that the similarities in the negative conversion rate of HBe Ag( RR = 2. 09,95%CI[0. 90,4. 85],P = 0. 09,I2= 0%),the HBV-DNA negative rate( RR = 1. 49,95% CI[0. 56,3. 95],P = 0. 43,I2= 0%) and the changes in ALT levels before and after treatment( RR =-6. 28,95%CI[-72. 83,60. 27],P = 0. 85,I2= 99%),with no statistical difference. In terms of quality of life,Gantaishu Capsules can significantly alleviate the symptoms of hepatitis B patients,with less adverse reactions. Gantaishu Capsules and Dongbao Gantai Tablets were similar in antiviral effect. In this term,Gantaishu Capsules was superior to Dangfei Liganning Capsules. It can significantly alleviate the symptoms of chronic hepatitis B patients,with a good clinical safety.Therefore,it can be applied in the case of syndrome differentiation and treatment. In view of the low quality of the included studies,more high-quality clinical trials were required to confirm its efficacy.

Objective To establish an HPLC method for determining the content of swertiamarin in Gantaishu capsules. Methods Using a Waters Symmetry C18 column (4.6 mm×250 mm, 5μm), the mobile phase was acetonitrile-0.02%phosphoric acid, with flow rate of 1.0 mL/min. The detection wavelength was at 250 nm, the column temperature was room temperature. Results The content of swertiamarin showed a good linear relationship in the range of 0.373 556-2.988 448 μg, r 2=1.000 0. The average recovery was 106.81%, and RSD was 3.7%. Conclusion This method is fast, accurate and simple with good reproducibility, which can be applied to the quality control of Gantaishu capsules.
