摘要
One-dimensional chromatography with internal standards permits reliable identification of the phenylthiohydantoins from all the common amino acids with the following TLC systems: silica gel-chloroform/n-butyl acetate (90:10), di-isopropylether/ethanol (95:5), dichloromethane/ethanol/acetic acid (90:8:2) or trans-dichloroethylene/ethanol/acetic acid (88:10:2); and cellulose with 25% formic acid-heptane/isobutanol/75% formic acid (40:30:9) or silica gel-chloroform/ethanol/acetic acid/water (50:47:0.5:2.5).
