Abstract:
AIM: To observe the change of boiling point in the concentration of medical herb's extract liquor. METHODS: Extract liquors of typical herb. such as Radix salviae Miltiorrhizae, Flos chrysanthemi indici, Folium isatidis and Radix Astragli, were concentrated in the normal pressure, its boiling-points and mol concentrations were recorded and its curve was depicted. RESULTS: At the same concentration, the boiling points of different kinds of Chinese medicinal material is different. CONCLUSION: In the concentration process of distillation the change of solvent and solute should be taken into account.
