摘要：

Evaluation of the only available method for comprehensive total glycoalkaloid determination was carried out. The method comprised bisolvent extraction of glycoalkaloids followed by purification and non-aqueous titration of the aglycones released from the glycoalkaloids by acid hydrolysis. Our data show that use of the bisolvent extraction procedure can result in poor and variable recovery of glycoalkaloid standard. The post-extraction part of the analysis yielded high and reproducible recoveries of glycoalkaloid standard. © 1979, Springer. All rights reserved.
