Objective:To compare the effect of different processing methods on the content of Ginsenoside Rg 1 from Radix Notoginseng. Methods: The HPLC method was used for the determination. Chromatographic condition includes: C 18 column, acetonitrile water (45∶55) as a mobile phase, UV detector wavelength at 203nm, 25 ?C column temperature and 0.7 mL?min -1 of flow rate. Results: The content of Ginsenoside Rg 1 of the Radix Notoginseng powder was the highest among all samples. Its recovery was 95.53% and RSD was 2.11% . The correlation coefficient was 0.9999 . Conclusions: It is better to use Radix Notoginseng in the form of the Powder in clinic.

Objective To investigate the possible relationship between the vitamin E(VE) contents in the plasma and development of hepatosis.Methods VE and malondialdehyde(MDA) contents in 217 cases infected by various types of viral hepatitis were measured by means of fluorescence and TBA.Moreover,the relationship between both of the contents and the alteration of liver function was observed dynamically.Results The plasma levels of VE in all cases were decreased obviously.Interestingly,lower the contents of VE were,more severity the disease was.Howevey,the levels of VE recovered step by step when the liver function return to normal in the acute hepatitis cases.Unfortunately,the levels in the chronic hepatitis cases were higher in the recovering phase than in the acute phase,but still lower than normal.Moreover,VE kept low levels and showed a negative relationship to the bilirublin in both worsening and dying cases.Conclusion To observe the VE contents is helpful to the clinical evaluation of the hepatosis progress and prognosis.
