ABSTRACT

Objective To study the processing of origin integration method and technology of Rehmanniae Radix (RR) and prove the feasibility of this new and innovative way. Methods The processing of origin integration technology of RR was selected with appearance and character as indexes, and thinking of appearance traits, content of catalpol, acteoside, rehmaionoside A, D and leonuride as an index, adopting comprehensive index scoring method to select the new processing of origin integration technology of RR. Results The optimized technology of the processing of origin integration of RR was as follows out 2—6 cm diameters of fresh RR, baked completely at 75 ℃, piling up and sweating for 12 h, cutting 4—5 mm thick slices, dried at 75 ℃ up to 4—5 h, taking out and packing after cooling. Conclusion Adopting the processing of origin integration technology directly processes fresh RR into RR decoction pieces, which is simple as well as convenient, reducing the repeated processing and storage steps and achieving the aim of reducing the processing cost on Chinese herbal medicines and improving the quality of Chinese medicine decoction pieces.
