title: [Study on applicability of kinetic model for water extracts from puerariae radix].
abstract: To establish an appropriate experimental and data processing method on the basis of the general kinetic model for extraction of traditional Chinese medicines, in order to study the effect of total flavonoids in water extracts from Puerariae Radix on the adaptability of the model, with total flavonoids of Puerariae Radix as the determination indicator. The results showed that the natural logarithm of mass concentration of total flavonoids showed a good linearity with the changes in extraction time and solvent volume. Through calculating and fitting, we successfully established the kinetic model for water extraction of total flavonoids from Puerariae Radix, and verified its accuracy. Its good fitting degree and controllable deviation within the range of industrial production requirements indicated a good adaptability of the model. However, its equation correction factors require further studies.
