Study On The Still Stangding Process Of Yang Yin Qing Fei Tang Jiang

Yang Yin Qing Fei Tang Jiang was triturated by TIAN JIN LERENTANG PHARMACERTICAL FACTORY, and put in the market in 1980. The production is selling well of the whole world in the near 30 years. But this production was triturated earlier, the water extraction alcohol deposition craft is used for ever, the production is laid on some time, it could appear precipitation phenomenon(It can not dissolve by swaying), the effective component well reduce along. To eliminate the precipitation, during the preparation, it has to increase alcohol and extend still standing time. The traditional craft causes to increase the man-hour, the material and energy consumption, causes to reduce the production efficiency, It is also difficult to fulfil the mass continuous production need.This topic research is precisely studied on the still standing craft of Yang Yin Qing Fei Tang Jiang, it adopts high-speed centrifugal and barrier separation to replace the traditional water extraction alcohol deposition. Using mathematical statistics in orthogonal method, it explores centrifuge rotation speed, solution temperature, speed of flowing to in its solution of high-speed centrifuge which influences indexing ingredient; it explores the inorganic ceramic barrier aperture, the solution temperature, the transfer pump pressure which influences indexing ingredient, it confirms best parameters conditions of the two crafts. Then it prepares the production of mid-experiment, it compares the effective content and fingerprint spectrum with the productions which prepared by the new craft and traditional craft. To increase the precise of comparison, it increases the two internal standard of paeonol and glycyrrhizin acid as it is based on measuring paeoniflorin in Yang Yin Qing Fei Tang Jiang, then it proves this methods, it makes sure the feasibility of the new craft pursuantly. At last it products 3 productions by the best craft and it explores the stability on the quick experiment of 3 months. It filtrates the high-speed centrifuge as the best craft instead of water extraction alcohol deposition by the comparison of results and economic factor.This topic uses the high-speed centrifuge technology to replace the water extraction alcohol deposition to solve the deposition and the problem by depositing. The high-speed centrifuge technology is used on active production, the production technology and quality can be increased, the cost can be reduced, the competitive power in same profession market can be raised.
