[Study of hydroscopicity of Glycyrrhiza uralensis Fisch].

OBJECTIVE: To study hydroscopicity of Glycyrrhiza uralensis Fisch and screen the best compounding of adjuvant, and measure critical relative humidity of the best anagraph for providing reasonable relative humidity of production. METHODS: Different adjuvant were adopecd and compared hydroscopicity of Glycyrrhiza uralensis Fisch at 25 degrees C and different relative humidity. RESULTS: The best prescription was Glycyrrhiza uralensis Fisch: lactose: microcrystalline cellulose = 1: 0. 5: 0. 5. The critical relative humidity of prescription was 60%. CONCLUSION: The sduty can solve the problem of mositure absorption and agglomeration in production.
