Woodwardia And Chemical Composition Of Processed Products

In our researches, on the basis of chemical and pharmacological studies, processing principle of the rhizome of Cibotium barometz was discussed. The best processing technology was studied by orphonogal test to provide the theoretical basis for the researches in quality standard of processed products of the rhizome of C. barometz.Our studies were performed in the following three aspects:Chemical researchesThe increasing principle of protocatechualdehyde, protocatechuic acid in C. barometz was discussed with HPLC.The difference of HPLC between the raw and processed samples was compared. By studying,it was found that the Compositions in C. barometz not only have the change of quantity, but also have qualitative difference after it was processed.Processing verificationBy orthogonal design,it can verificate the best procedure for processing in the pre-processing procedure.Market study on th Quality of the rhizome of Cibotium barometzThese methods,which including characters identification,Determination of moisture ,ash method for determination ,etc. teat the five groups of the rhizome of C. barometz.To protocatechuic acid, protocatechuic aldehyde for reference substance on the marketing the five groups of the rhizome of C. barometz. of qualitative and quantitative detection.
