| 1 | Stability Test of Naomai Xingshen Capsules显示文摘[Objectives]To explore the stability of Naomai Xingshen Capsules.[Methods]Accelerated test and long-term test were carried out to investigate the changes in properties,identification,moisture,disintegration time and microbial limit of Naomai Xingshen Capsules.[Results]There were basically no changes in all indicators for the three batches of samples(after 6-month accelerated test and 24-month long-term test),and they all met the requirements of quality standards.[Conclusions]The preparation of Naomai Xingshen Capsules is stable and reliable,and the stability test provides a reliable basis for its expiration date. | Congyan ZENG Xiaoyan PANG Yuliang HU Xiaofang XIN | 2022 | Medicinal Plant2022，13，4： | 0 |
| 2 | Extraction and Drying Technique of Bawei Shangke Huoxue Tablets显示文摘[Objectives]To optimize the water extraction process of Bawei Shangke Huoxue tablets and determine the best drying method of the extract.[Methods]The orthogonal test method was used to select the optimal water extraction process,with the content of total flavonoids and the yield of dry extract as the test indicators,and the soaking time,the amount of water added,the extraction time and the extraction times as the main test factors.The water content of spray powder was taken as the evaluation indicator,the inlet air temperature,the density of liquid phase and the outlet air temperature were selected as the factors,and the spray drying process of water-extracted concentrated liquid was optimized by orthogonal test.[Results]The optimal water extraction process was no immersion,water decoction and extraction twice,adding 10 times of water each time,extraction for 1h,in which the amount of water added was the main factor.The liquid density of spray dried extract powder is 1.05-1.08(60℃),the inlet air temperature is 180℃,the outlet air temperature is 80℃is the most suitable,and the liquid density is the main factor.[Conclusions]The extraction and drying technology of Bawei Huangke Huoxue tablet is feasible,scientific and reasonable,and can be used for industrial production. | Lili YAN Chunyan SU Congyan ZENG Xuelong WU | 2022 | Medicinal Plant2022，13，6： | 0 |
| 3 | Experimental Study on the Stability of Shuji Tablets显示文摘[Objectives]To investigate the stability of Shuji tablets.[Methods]Accelerated test and long-term test were used to investigate the changes of tablet properties,weight difference,alcohol-soluble extract,disintegration time and microbial limit.[Results]All the indicators of the three batches of samples(after 6 months of accelerated test and 18 months of long-term test)basically remained unchanged and all met the standards of the quality standard.[Conclusions]The preparation is stable and reliable,and the stability test provides a reliable basis for its validity. | Cui YAN Congyan ZENG Yuliang HU Xiaofang XIN Xiaoyan PANG | 2022 | Medicinal Plant2022，13，6： | 0 |
| 4 | Drying Technology and Formation Process of Naomai Xingshen Capsules显示文摘[Objectives]To optimize the drying technology and formation process of Naomai Xingshen Capsules.[Methods]The yield of paste powder and moisture content as evaluation indicators were taken as indicators,the relative density of feed liquid,inlet air temperature and dosage of excipients were selected as investigation factors,the orthogonal experiment method was used to optimize the spray drying process.The moisture absorption rate and angle of repose were taken as evaluation indicators,the types of forming excipient were screened,and the critical relative humidity was determined.[Results]The optimum spray drying process was that the relative density of liquid medicine was 1.05(60℃),the air inlet temperature was 200℃,and the dosage of excipients was 2%.The effect of using dextrin as a forming excipient was better,and the relative humidity of the production environment should be controlled below 65%.[Conclusions]The optimized process is stable,feasible,scientific and reasonable,and can be used for large-scale industrial production. | Congyan ZENG Yu ZHANG Bin ZHUO Shi LIANG Yuliang HU | 2022 | Medicinal Plant2022，13，2： | 0 |
