石花炮制工艺优化研究

摘要

目的：根据石花的蒙医炮制目的，优化石花炮制工艺。方法：在老蒙医大夫的指导下，以药材的脆性为指标，通过水分含量的监控，优化传统炮制方法的最佳工艺条件，同时借鉴最佳传统炮制品，确立石花炮制烘干法。结果：石花微炒炮制方法的适宜条件为110℃﹑3 min。在此条件下其水分含量均在4.14％～4.63％之间，重复性较好。水洗处理后石花炮制品的总灰分虽然没有明显改变，但酸不溶性灰分有明显下降，下降率可达到5％。烘法的最佳条件为60℃、3 h。结论：建议蒙药石花炮制前水洗处理，微炒的适宜条件为110℃﹑3 min；烘法的最佳条件为60℃和3 h；炮制品水分应控制在4.1％～5.0％之间。第二种方法方便易行，工时短，有利于规模化生产。%Objective:To optimize the processing technology for Shihua according to processing purpose of Mongolian Medicine of Shi -hua.Methods:Under the instruction of doctors on Mongolian medicine , taking brittleness of the medicine as the index , through monito-ring contents of water, optimizing processing conditions of traditional processing technology , and utilizing techniques from best traditional processed medicine, and finally the processing method of Shihua was indentified .Results:The suitable condition for light stir-frying process of Shihua was the temperature of 110℃in 3 minutes.In this condition the moisture content was in the range of 4.14 to 4.63%, and repeatability was good.After water wash, the total ash of Shihua didn′t change significantly, but acid insoluble ash obviously de-creased by 5%.The best condition for drying process of Shihua was 60℃in 3 hours.Conclusion:Water wash before processing is sug-gested.The suitable condition for light stir-frying process of Shihua would be the temperature of 110℃in 3 minutes.The best condition for drying process of Shihua would be 60 ℃in 3 hours.The moisture of the processed products should be controled in the range of 4.1 to 5.0%.The second method is convenient , feasible with shorter working hours , and suitable for large-scale production.
