Abstract:

A method of the quantitative analysis was established for the determination of deacylgymnemic acid (DAGA) in the alkaline hydrolysate of the sample containing gymnemic acids which are ingredients of Gymnema sylvestre R. BR. leaves, by means of high-performance liquid chromatography. This method was used for comparing the contents of gymnemic acids in various samples. The amount of gymnemic acids analyzed as DAGA in 70% ethanol extract of dry leaves was about twice that in hot water extract. The commercial health-supplemental foods of five companies were investigated for the contents of gymnemic acids as DAGA and there were large differences from 38 to 251 mg in the dosage per day recommended by each company.
