Comparative study of extraction on Rhubarb through multiple linear regression and range analysis / 中成药

ABSTRACT

Objective: To optimize the extraction process for Rhubarb. Methods: Colomrimetric analysis was used to measure the content of active ingredients; Besides, orthogonal design was applied to optimize the technologies of Rhubarb in comparision with two ways to deal with the experimental results. Results: The different optimum extraction processes can be obtained by different ways to deal with the experiment results but the same experiment results were found. Conclusion: The multivariate regression analysis can make up shortage of sense The equation of regression is more helpful for explanation of result and optimum of preparation technology.
