The Determinnation of Steroidal Alkaloid Content in Solanum nigrum L

Abstract

Abstract: Objective:To establishing a method of steroidal alkaloids extraction and detecting also assay method in Solanum nigrum L.Method:After extracting solancarpidine by the method of ethanol extracting-hydrolyzing with acid and ethanol,solan carpidine is analyzed;By detecting solancarpidine,the content of steroidal alkaloids is also to be learned by using solancarpidine as reference.Conclusion:The content of steroidal alkaloids is determined rapidly and accurately by the new method of steroidal alkaloids’s extraction and detecting;the steroidal alkaloids whose hydrolysate is solancarpidine in Solalum nigrum L has been found mainly in its immature fruits,but a little in stems and leaves.

Key words: , solancarpidine； solalum nigrum L alkaloid； HPLC； herb extraction；
