A gas chromatographic procedure is described for quantitative estimation of alpha-hydroxy-beta 1 beta-dimethyl-gamma-butyrolactone (pantolactone). The chromatography was carried out using "LHM-8MD" apparatus equipped with a flame ionization detector. Columns with chromaton N-AW modified by 5% silicone XE-60 were used, helium
