Process for determining the tomatoside concentration in the dry extract of tomato seeds

摘要

The invention relates to a process for determining the tomatoside concentration in the dry extract of tomato seeds and may be used in chemistry and medicine. The claimed process consists in dissolving the dry extract of tomato seeds in the 40...50% ethyl alcohol solution, addition to the obtained solution of the Erlich reagent in the ratio of 1:2 correspondingly. The thermostatic control of the obtained reacting mixture is carried out at the temperature of 40 degree C within at least 60 min, and the dilution of the formed colored complex solution with methanol is carried out in the ratio of 3:1 correspondingly. Afterwards, it is measured the optical density of the colored solution and it is calculated according to its value the tomatoside concentration.The result of the invention consists in the acceleration of the process, as well as in increasing the accuracy thereof.Claims: 1
