中药虎杖贮藏养护的初步研究

Preliminary Research on Storage and Curing about Rhizoma Polygoni Cuspidati

目的:研究30个月内不同贮藏条件下中药虎杖的外观质量、水分、浸出物含量的变化情况。方法:以养护前处理、包装材料、对抗剂、贮藏温度为考察因素,设计4因素3水平9组正交试验,以药材外观质量,水分(或干燥失重)、浸出物作为考察指标,采用正交统计方法分析整理试验结果,初步筛选虎杖的最佳贮藏养护方法。结果:随着虎杖贮藏时间的延长,因贮藏方法的不同,各项考察指标变化存在明显差异。结论:白酒不宜作为虎杖药材的对抗养护剂;在密封、避光条件下,以丙三醇或生石灰作为对抗养护剂,能较好的对虎杖药材进行贮藏养护,为虎杖贮藏养护的进一步研究提供实验依据。

Objective Under the different storage conditions,research on the changes about the exterior quality,moisture and extract content of Rhizoma Polygoni Cuspidati in 30 months.Method Designing 4 factors（pretreatment conserve,packaging materials,antagonist and storage temperature） and 3 levels orthogonal test and taking the exterior quality,moisture or dry weightlessness and extract content as guidelines,the best storage and curing methods was determined primarily with orthogonal experiments and statistical analysis.Result With the extension of storage time and the different storage and curing methods,each index showed obvious differences.Conclusion Liquor is not as the antagonist of Rhizoma Polygoni Cuspidati but glycerin or caustic lime can better for the storage and curing in conditions of sealing and avoid light.This paper provided the experiment basis for further research on the storage and curing of Rhizoma Polygoni Cuspidati.
