Abstract

The invention discloses a storage method of rhubarb. The method comprises the following steps of: (1) pretreatment, namely treating rhubarb by <60>Co radiation or intermittent freezing; and (2) storage, namely packaging the rhubarb treated in step (1) with woven bags or plastic bags, and storing the rhubarb using quick lime or glycerine as an antagonist at normal temperature or low temperature in a sealed and shaded mode. The storage method of rhubarb can maintain the quality and medicinal effect of the rhubarb effectively for long time, and has good application prospect.

Description

technical field [0001] The invention relates to a storage method of rhubarb. Background technique [0002] Rhubarb is the dry root and rhizome of Rheum palmatum L., Rheum tanguticumMaxim.ex Balf. or medicinal Rheum officinale Baill. of Polygonaceae. Rhubarb is prone to deterioration such as insects, mold, and discoloration during storage, which seriously affects the quality and efficacy of this kind of medicinal materials. Its unstable components such as hydroxyanthraquinones and tannins are one of the reasons for the deterioration. one.
