摘 要:目的:比较不同干燥方法对番泻叶提取物中番泻苷B的影响。方法:以番泻苷B含量为指标,采用单因素试验考察减压浓缩和真空干燥时不同温度的影响;通过正交试验考察进风温度、出风温度及喷速对番泻叶提取物喷雾干燥工艺的影响。结果:番泻叶提取物减压浓缩和真空干燥时最佳温度均为60℃,耗时分别为87 min,58 h;优选的喷雾干燥工艺为进风温度120℃,出风温度55℃,喷速16 mL.min-1。结论:与喷雾干燥相比,真空干燥时番泻苷B含量损失较多;喷雾干燥既节约时间又有利于有效成分的保留,优选的喷雾干燥工艺稳定可行,可用于对热不稳定的番泻叶提取物的干燥。Objective:To compare effect of different drying methods on the content of sennoside B in Cassia angustifolia extracts. Method: With the content of sennoside B as index,effect of reduced pressure condensing and vacuum drying at different temperatures on the content of sennoside B were investigated by single-factor test; Orthogonal test was used to investigate influence of inlet temperature,outlet temperature and spray velocity on spray drying technology of C. angustifolia extracts. Result: Optimal temperature of reduced pressure concentrating and vacuum drying for C. angustifolia extracts were 60 ℃,their time-consuming were 87 min,58 h,respectively;Optimum spray drying technology parameters were as followings:inlet air temperature 120 ℃,outlet air temperature 55 ℃,spraying velocity 16 mL·min-1. Conclusion: Loss of sennoside B by vacuum drying was more than spray drying; spray drying was time saving and beneficial to retention of effective ingredients,optimized spray drying process was stable and feasible,and it could be used for drying of C. angustifolia extracts with thermal instability.
