(−)-Epigallocatechin gallate (EGCG) was purified in one step from a green tea polyphenol (GTP) crude extract by adsorption chromatography on a Superose 12 HR 10/30 column. The mobile phase used was a mixture of acetonitrile and water with an optimum mobile phase compositions regarding purity, recovery and separation time of 78/22 (v/v). Maximum practical sample loading was 100mg GTP per run (corresponding...
A new adsorption chromatographic method for the simultaneous purification of Danshensu, Protocatechuic aldehyde and Salvianolic acid B (Lithospermic acid B) from a crude extract from radix of Danshen (Salviae miltiorrhiza) has been developed using oligo-β-cyclodextrin immobilized to Sepharose HP agarose gel media. Sample loads of up to 2.3mg crude extracts/ml gel gave satisfactory results. The target...
