Problems solved by technology

[0005] However, the rhizomes of white water lilies also contain betulinic acid. At present, there are few studies on the extraction of betulinic acid from the rhizomes of white water lilies, and the technology is immature. Therefore, betulinic acid is extracted from the rhizomes of white water lilies. Has great application potential and great significance

Embodiment 1

[0041] refer to figure 1 , a kind of extraction process of white water lily rhizome extract, comprises the steps:

[0042] S1: pre-processing. Get the rhizome part of fresh white water lily, and it is washed, air-dried and dried, then pulverized, and pass 80 mesh sieves.

[0043] S2: extraction. The rhizome after the pretreatment of S1 was placed in the extract and soaked for 1.5 hours, and the mass ratio of the extract to the rhizome of White Water Lily was 13:2. After soaking for 1.5h, stir with a glass rod for 30min. The extracting solution includes ethanol solution and ethyl acetate, the mass ratio of ethanol to ethyl acetate is 8:2, and the volume fraction of ethanol is 70%.

[0044] S3: Suction filter the soaking solution after S2 extraction. Also comprise following steps after suction filtration:

[0045] a. Soak the filter residue after S3 suction filtration in a methanol solution with a volume fraction of 70%, and the soaking time is 3 hours.

[0046] b. The so...

Abstract

The invention relates to the technical field of an extraction technology for a nymphaea alba rhizome extractive and discloses the extraction technology for the nymphaea alba rhizome extractive. The extraction technology comprises the following steps: S1) pretreatment: cleaning, drying and smashing nymphaea alba rhizome; S2) extracting: using an extracting solution for soaking the rhizome after thepretreatment in step S1), wherein the extracting solution includes an ethanol solution and the mass ratio of extracting solution to nymphaea alba rhizome is at 13:2; S3) performing suction filtrationon the extracting solution treated in step S2); S4) adding the ethanol solution into filtrate after suction filtration in step S3); S5) secondarily extracting the solution treated in step S4; S6) removing solvent from the solution treated in step S5, thereby acquiring betulinic acid. Under the existence of ethanol, the nymphaea alba rhizome can be extracted; through subsequent treatment, the solvent can be separated from the system and only betulinic acid crystal is remained; ethanol has higher penetrability, so that ethanol is capable of extracting betulinic acid from deeper part of nymphaeaalba rhizome.

Description

technical field [0001] The invention relates to the technical field of white water lily extract, more specifically, it relates to an extraction process of white water lily rhizome extract. Background technique [0002] Water lily is also called hibiscus. The rhizome part of the water lily is the lotus root, and the fat lotus root is mostly white to brown. Water lily starch tastes slightly sweet, and tastes crunchy and delicious. It can be eaten raw or cooked. It has quite high medicinal value, and all parts of it are treasures. Processing water lilies into water lily powder has many effects, such as preventing internal bleeding. There are many kinds of water lilies, which can be divided into different categories according to different purposes. [0003] White water lily, also known as European white water lily, is a plant of the genus Nymphaea that originated in Europe. Petals white, calyx green, tip white. Anthers yellowish, slightly tomentose. The leaf surface is g...
