| 摘要: |
| 目的 探讨醇沉对清利咽喉浸膏粉吸湿性的影响。方法 测定不同醇沉浓度所得清利咽喉浸膏粉在不同湿度环境下的吸湿率与临界相对湿度（critical relative humidity，CRH），绘制各浸膏粉在不同湿度环境下的吸湿速度曲线，用Origin 2018统计软件对实验数据进行处理。结果 在25℃条件下，RH低于48.52%，各浸膏粉的吸湿率均低于5%；RH为57.70%，醇沉浓度对吸湿性无显著影响；RH 75.28%、84.26%、92.40%时，50%醇沉浓度的干浸膏粉吸湿率最小，分别于6.49 h、4.04 h、3.42 h，吸湿率达5%；各浓度醇沉浸膏粉的CRH大约为49.34%。结论 不同醇沉浓度对清利咽喉浸膏粉吸湿性有影响，且RH越大，其影响越显著。 |

| Abstract: |
| Objective To investigate the effects of alcohol precipitation on hygroscopicity of Qingli Yanhou extract powder. Methods The hygroscopic rate and critical relative humidity (CRH) of Qingli Yanhou extract powder obtained by different alcohol concentration in different humidity environment were measured, and the hygroscopic speed curve of each extract powder in different humidity environment was drew. The experimental data was processed with Origin 2018 statistical software. Results Under the condition of 25℃, when RH<48.52%, the hygroscopic rate of all extracts was lower than 5%. When RH was 57.70%, the alcohol precipitation concentration had no significant effect on hygroscopicity. When RH was 75.28%, 84.26% and 92.40%, the dry extract powder with 50% alcohol precipitation concentration had the smallest hygroscopic rate, which reached to 5% in 6.49 h, 4.04 h, 3.42 h. CRH of extract powder with each alcohol precipitation concentration was about 49.34%. Conclusion Different alcohol precipitation concentration has an effect on the hygroscopicity of Qingli Yanhou extract powder, and the greater RH is, the more significant effect is. |
