正交试验优化当归趁鲜切片的加工工艺

Optimization of the Processing Technology for Slices from Fresh Angelica sinensis Diels by Orthogonal Design

目的通过药物成分含量检测与正交试验相结合的方式,确定当归趁鲜切片的工艺流程及工艺参数。方法先考察鲜当归杂质处理方法、切片的厚度及其干燥的方式对当归趁鲜切制外观性状、内在结构和药物成分(阿魏酸、挥发油)含量的影响。然后采用L_(9)(3^(4))正交试验,对当归饮片中阿魏酸含量进行分析,选出当归趁鲜切制的最适宜工艺条件。结果通过正交试验优化得到最适宜当归趁鲜饮片加工工艺为:首先将鲜当归除去芦头、须根和泥沙,并用水洗净其表面泥土和杂质,稍晾至没有水滴下滴时,放入温棚日晒干燥,直到当归归须和归尾(直径在5 mm以内)已干燥,归身变软,再将全当归切成4 mm薄片,最后放置在温棚日晒干燥,即得当归饮片,其饮片中阿魏酸含量为0.2211%,挥发油含量为0.9%;当归趁鲜切制最适宜工艺所得的当归饮片质量优于传统方法所得的质量(阿魏酸含量为0.1930%,挥发油含量为0.8%)。结论所得的加工工艺合理、可行,为后期当归趁鲜切片工艺研究奠定基础。

Objective This study aims to optimize the processing technology and parameters for fresh slices of Angelica sinensis Diels by combining medicinal component content detection with orthogonal testing.Methods The effects of impurity treatment methods,thickness,and drying methods on the appearance,internal structure,and content of medicinal components(ferulic acid and volatile oil)in fresh slices of Angelica sinensis Diels were investigated.The processing technology for fresh slices of Angelica sinensis Diels was then optimized using an L_(9)(3^(4))orthogonal test,with the ferulic acid content as the index.Results The optimized processing technology and parameters for fresh slices of Angelica sinensis Diels were determined as follows:First,the reed head,the fibrous roots,soil and impurities were removed or washed from the surface of the plant.The sample was then dried until there was no water dripping from the surface.Next,the plant was dried in a greenhouse until the cloud Angelica must and the tail(diameter within 4 mm)became dry,and the body became soft.The whole plant was then cut into 4mm thick slices and further dried in the greenhouse,and the yun angelica Yinpian are obtained.The ferulic acid and volatile oil contents were 0.2211%and 0.9%respectively.The quality of Radix Angelicae sinensis slices processed using this optimized technology is superior to that of slices obtained by traditional methods(the acid and volatile oil contents were 0.1930%and 0.8%).Conclusion The optimized processing technology is reasonable and feasible,laying a solid foundation for the pharmaceutical processing of fresh slices of Angelica sinensis Radix.
