【摘要】 采用香草醛-高氯酸比色法测定苦瓜总皂苷含量,考察苦瓜总皂苷在不同条件下的稳定性,对开发苦瓜总皂苷保健食品具有一定的参考价值。实验以性状、熔点、吸湿性、皂苷含量为考察指标,分别考察了高温、高湿、紫外线照射、不同pH值条件下对苦瓜总皂苷含量的影响。结果表明,苦瓜总皂苷在50℃以下,pH6.0～9.0的干燥密闭条件下比较稳定,且紫外线照射对苦瓜总皂苷含量无影响。因此,开发苦瓜总皂苷保健食品具有可行性。更多还原

【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.更多还原
