[Studies on factors influencing on ephedrine contents in Maxing Shigan decoction].

Objective: To investigate the factors influencing on the ephedrine contents in different compositions of Maxingshigan decoction.

Method: Adopt mixed uniform design to dismantle recipes, employ the stepping regression analysis to deal with experimental statistics, use the partial correlational analysis to analyze the correlation coefficients and the results were validated.

Result: The regressive equation was of significance, that is Y = 4.
