Processing of origin integration method and technology of Rehmanniae Radix / 中草药

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.

Effect of rehmaionoside A on cyclophosphamide induced leukopenia in mice / 中草药

Object To observe the effects of rehmaionoside A on mice leukopenia models induced by cyclophosphamide. Methods Mice leukopenia models were prepared by ip cyclophosphamide and then treated with rehmaionoside A. The levels of body weight, peripheral hemogram, reticulocyte count, spleen index, bone marrow karyocyte count and contents of bone marrow DNA were determined. Results Rehmaionoside A could obviously raise the counts of white blood cell, red blood cell, platelet, reticulocyte and bone marrow karyocyte, contents of bone marrow DNA, and body weight of the leukopenia model. Conclusion Rehmaionoside A has apparent leukogenic and antianemic actions.
