Abstract: Aim: Finding the best method to extract the antihypertensive substance in the red yeast rice. Method: We find the best way by the Orthogonal Design Method and isolated aorta to check the activity. Result: We find the best way is to be immersed in 50% ethanol at 80℃ in water bath for 1hour, suction-filtered and then mixed and shaken with cyclohexane. This way not only improves the activity of antihypertensive substance but also improves the output.

Key words: red yeast rice, orthogonal design method, isolated aorta, extraction process
