Isolation of sarcosine from an acid hydrolysate of groundnut protein.

Abstract

A TWO-DIMENSIONAL paper chromatogram of an acid hydrolysate of groundnut protein has shown, in addition to the spots due to the amino-acids previously reported present in groundnut protein1, a glycine spot (RF = 0.32, 80 per cent aqueous phenol; RF = 0.22, butanol–acetic acid) and an unidentified spot (RF = 0.78, 80 per cent aqueous phenol; RF = 0.24 butanol–acetic acid mixture). The RF values of the unidentified spot did not correspond with any of the values reported for amino-acids2 or amino-sugars3.
