TI  - Determination of gymnemic acid level in Gymnema inodorum leaves using multiple reaction monitoring mass spectrometry
AB  - Abstract: Gymnemic acid (GA) is known as the antidiabetic phytoconstituent in Gymnema species, and is usedfor quality control and standardization of Gymnema products. In Thailand, a number of nutraceutical products ofGymnema inodorum (Lour.) Decne. (GI) are commercially available and this number is increasing. However,standardized GA content information and safety usage guidelines for GI have not been published. The aim ofthis study was to investigate the amount of GA constituent in GI leaves using mass spectrometry. Leaf sampleswere randomly collected in the Northern part of Thailand. Total GA was extracted using an ethanolic solution.The calculation of total GA was based on the detection of aglycone gymnemagenin using the liquidchromatography/electrospray ionization mass spectrometry with multiple reaction monitoring. The resultsshowed that GI contained total GA content in range of 0.20-1.44 mg per one kilogram dry leaves.
