Study of the Optimal Condition for Maximum Extraction Efficiency in Armeniacae Semen Powder

Armeniacae Semen is a seed of Prunus armeniaca Linne var. ansu Maximowicz, which belongs to Rosaceae family. It contains amygdalin and fatty oil and is widely used to treat asthma, dysponea and edema. It was reported that D-amygdalin in Armeniacae Semen undergoes hydrolytic reaction by emulsin when using water, and esecially it is almost decomposed when extracting from powder type. we set up a condition where we can achieve the maximun extraction yield through the study of the methods to rstrain emulsin from causing hydrolysis of D-amygdalin in Armeniacae Semen in the aqueous solution and to prevent D-amygdalin from being converted into neoamygdalin.
