title: [Glycyrrhizinic Acid Reference Standard (Control 031) of National Institute of Health Sciences].
abstract: The raw material of glycyrrhizinic acid was examined for preparation of the "Glycyrrhizinic Acid Reference Standard". The analytical data obtained were: UV spectrum: lambda max, 251 nm; and specific absorbance (E(1 cm)1%) in ethanol at 251 nm, 146.4; IR spectrum, specific absorptions of raw material were consistent with those of Standard (Control 0221). Also, thin-layer chromatography, no impurity was detected; high-performance liquid chromatography, several impurities were detected. The amount of each impurity was estimated at less than 0.2% and total amount of impurities was less than 0.2%. Based on the above results, the candidate material was authorized as the Glycyrrhizinic Acid Reference Standard (Control 031) of the National Institute of Health Sciences.
