Abstract: The content of momordicosides in Momordica charantia L. extract by 70% ethanol was determined by colorimetry to investigat respectively their stabilities to high temperature,high humidity,ultraviolet irradiation time and pH value. The main assessment indexes were appearance characters,melting points,moisture absorption and content of momordicosides. Momordicosides exist steadily below 50 ℃ and between pH 6.0 and pH 9.0 in dry and airtight environment. And the content of momordicosides is not influenced by ultraviolet irradiation time. So the application of the momordicosides in health food industry has feasibility.

Key words: Mommordica charantia L., momordicosides, stability
