Application of Computation Method of T''''s Correlation Degree in Orthogonal Design Optimized Extraction Process

OBJECTIVE: To compare the results of T's correlation degree analysis and variance analysis on application of orthogonal design to optimize extraction process. METHODS:The process for extraction of crude polysaccharide from Hedyotis diffusa was taken as an example. T's correlation degree analysis and variance analysis were separately adopted to study the correlation of extraction factors and indexes in orthogonal design. RESULTS: The result of T's correlation degree is same as that of variance analysis. CONCLUSIONS:T‘s Correlation Degree method is economical, simple and efficient,and can be used to optimize computation method of extraction process.
