Abstract:
A Dew Don-protein amino acid. erylkro-y-hydroxyhomo-L-arlinine has been isol8ted from seed of
Lort£iwcarpt4 cosraricmsis by exploiting its property of interacting with borate ions. For structural comparisoD1. rlveor-
hydroxyhomo-L-arainine was isolated from seed of Lath yrw lingirQJIus and eryrkro-y-hydrollyarginine from V'acl'D
IlIIIjuga by novel procedures. The rcasom for the interaction of borate with the n-yllv~ but not the rhrto-forms ofthcse
am ino acids are discussed.
