Embodiment 1

[0017] The preparation method of purple jade yam extract includes the following steps: pulverize dry purple jade yam yam to 75 meshes to obtain purple jade yam yam dry powder, wherein the crushed purple jade yam yam is the tuber part; take the purple jade yam yam dry powder and add boiling water. The liquid ratio is 1:25, and the mixture is evenly mixed. The extraction is carried out in boiling water for 3.5 hours. After cooling, the supernatant is collected by centrifugation. The supernatant is added with 0.7% neutral protease based on the weight of the dried purple jade yam powder. pH to 7, and stir for 1.5h at 45℃; after stirring, heat to boiling and continue for 18min. After the liquid is cooled, centrifuge, collect the supernatant, add absolute ethanol to the supernatant, the volume ratio of the two is 1:5, continue to stir, centrifuge, and collect the precipitate; wash the precipitate with anhydrous methanol, and air-dry the washed precipitate to obtain the purple jade yam...

Embodiment 2

[0021] The preparation method of purple jade yam extract includes the following steps: pulverize dry purple jade yam yam to 78 meshes to obtain purple jade yam yam dry powder, wherein the crushed purple jade yam yam is the tuber part; take the purple jade yam yam dry powder and add boiling water. The liquid ratio is 1:27, the mixture is evenly mixed, and the extraction is carried out in boiling water for 3.7 hours. After cooling, the supernatant is collected by centrifugation; the supernatant is added with 0.9% neutral protease based on the weight of the dried purple jade yam powder. pH to 7, and stir for 1.5h at 45℃; after stirring, heat to boiling and continue for 18min. After the liquid is cooled, centrifuge, collect the supernatant, add absolute ethanol to the supernatant, the volume ratio of the two is 1:6, continue to stir, centrifuge, and collect the precipitate; wash the precipitate with anhydrous methanol, and air-dry the washed precipitate to obtain the purple jade yam...

Abstract

The invention discloses a preparation method of a purple Chinese yam extract. The preparation method includes the following steps that purple Chinese yam dry powder is obtained and added into boiled water to be evenly mixed, the material-to-liquid ratio is 1:(22-28), extraction is conducted for 3.2-3.8 h in the boiled state, centrifugation is conducted after still standing and cooling, and supernatant is collected; neutral protease accounting for 0.5-1.0% of the weight of the purple Chinese yam dry powder is obtained and added into the supernatant, the pH is adjusted to 6-8, and the materials are stirred for 1-2 h at 40-50 DEG C; after stirring is completed, the mixture is heated to be boiled for 15-20 min, centrifugation is conducted after the liquid is cooled, supernatant is collected, absolute ethyl alcohol is added into the supernatant in the volume ratio of 1:(4-6), stirring continues, centrifugation is conducted, precipitate is collected, and the purple Chinese yam extract is obtained. The invention further discloses the purple Chinese yam extract prepared through the method and application of the extract. The prepared purple Chinese yam extract can be used for treating hyperglycemia.

Description

Technical field [0001] The invention relates to the technical field of biomedicine, in particular to a purple jade and yam extract and its preparation method and application. Background technique [0002] Purple jade yam has a purple-red flesh and a good taste. It is a traditional medicine and edible food with a long history of edible and medicinal use in my country. The medicinal value of purple jade yam is extremely high. It has the effects of invigorating the kidney, strengthening the spleen and stomach, and moisturizing the fur.
