ABSTRACT

Objective:

The phase separation of Baihutang was carried out. The content of mangiferin,new mangiferin,calciumion,glycyrrhizin and ammonium glycyrrhizinate in the solution phase,the nano phase and the precipitated phase of Baihutang were measured,so as to define the effect of nanometer particles of Baihutang on the growth of active components,and explain the mechanisms of Baihutang in potent detoxification and heat removal.

Method:

The phase separation of Baihutang was performed by high-speed centrifugation and dialysis. The contents of mangiferin,new mangiferin,glycyrrhizin and ammonium glycyrrhizinate in Baihutang were determined by HPLC. Chromatographic column Diamonsil C18 (4.6 mm×250 mm,5 μm) was adopted, with acetonitrile-25 mmol·L-1 potassium dihydrogen phosphate solution as the mobile phase, and eluted in a gradient mode. The detection wavelength was 257 nm,the column temperature was 30 ℃,and the flow rate was 1.0 mL·min-1. EDTA-2Na solution was used to calibrate the calcium concentration in different phase states of Baihutang.

Result:

1 mL Baihutang nanoparticles contained 483.00 μg new mangiferin,1 068.88 μg mangiferin,219.93 μg glycyrrhizin and 187.10 μg ammonium glycyrrhizin,and the content of new mangiferin and mangiferin accounted for 89.4% and 89.9% respectively in 1 mL Baihutang. The new mangiferin and mangiferin in the nano phase were 230.0 and 23.3 times the true solution,and 8.5 and 14.4 times of the precipitation,respectively. The content of calcium ions in Baihutang in the nano phase was higher,accounting for 86.9% of Baihutang,and the content of calcium ions in Baihutang and Baihutang in the nano phase was higher than that in gypsum group.

Conclusion:

The content of main components in Baihutang in nanometer phase is significantly higher than that in other phases. The nanoparticles of Baihutang have a solubilizing effect on the main antipyretic components, such as mangiferin,mangiferin and calcium ions as well as the antitoxic components glycyrrhizic acid and glycyrrhizic acid. The mechanism of action of Baihutang is related to the formation of nanoparticles.
