Study on the Prevention of Racemization of Amygdalin
Studies were conducted to find suitable conditions for the prevention of racemization of amygdalin in aqueous solution.Evaluation of racemization was carried out by determination of the ratios of neoamygdalyn and amygdalin using a capillary gas chromatographic technique.Racemization of amygdalin in aqueous solution was accelerated by increases on pH and temperature, but racemization was low below pH 3.0 even with heating.Ascorbic acid is useful as an acidification reagent for the suppression of racemization, and has the added clinical benefit of vitamin C activity.Keywords - amygdalin; isoamygdalin separation; racemization; racemizati on prevention; capillary gas chromatography
