目的:优选无名异的炮制工艺。方法:以MnO2含量为指标,通过正交试验考察煅制温度、米醋用量、煅制时间对无名异炮制工艺的影响,考察炮制工艺对MnO2含量及药材显微形态的影响。结果:最佳炮制工艺为煅制温度700℃,米醋用量20%,煅制时间40 min;生品和炮制品中MnO2质量分数(x珋±s,n=3)分别为(6.13±0.50)%,(7.35±3.27)%;与生品相比,无名异经煅制醋淬后,在光学显微镜下观察到透明晶体的数量增加,在偏光显微镜下观察到有色晶体的数量增加,晶体的外型均呈块状或肾状。结论:优选的无名异炮制工艺稳定可行,为无名异的炮制工艺规范提供参考。
Objectives: Optimization of the same process. Methods: The effects of calcination temperature, the amount of rice vinegar and calcination time on the unnamed processing were investigated by orthogonal test. The effects of processing technology on the content of MnO2 and the microscopic morphology of the medicinal materials were investigated. Results: The optimal processing conditions were as follows: calcination temperature 700 ℃, rice vinegar dosage 20%, and calcination time 40 min. The contents of MnO2 in raw and processed products (x 珋 ± s, n = 3) were (6.13 ± 0.50) %, (7.35 ± 3.27)%. Compared with the raw product, the number of clear crystals increased under the light microscope, the number of the colored crystals increased under the polarizing microscope, Appearance were massive or kidney. Conclusion: The optimal process of unnamed processing is stable and feasible, which provides a reference for the specification of unnamed processing.
