    Abstract: L-PTC (L-phosphinothricin, L-2-amino-4-methylphosphino-butyric acid) is the active herbicidal component of D,L-PTC and can be obtained according to the invention when D,L-PTC derivatives which are N-acylated and esterified on the phosphinic acid group as well as optionally esterified or amidated on the carboxylic group, are treated with a hydrolytically active enzyme in an aqueous or aqueous-organic medium, in which process the L-PTC derivatives are selectively hydrolyzed on the N-acyl group or the modified carboxyl group, the resulting product mixture is resolved, and the desired L-PTC derivative is hydrolyzed to give the L-PTC and isolated by customary methods.
