Embodiment

[0052] 1. Preparation of Chlorella Polysaccharides

[0053] 1.1 Cultivation of Autotrophic Chlorella

[0054] The autotrophic Chlorella population was obtained from the Liaoning Academy of Marine and Fishery Sciences. The stock was transferred to 10 L of thrice boiled seawater and grown in F / 2 Mediam (12 hr dark: 12 hr light cycle).

[0055] Autotrophic Chlorella growth conditions: F / 2 (Guillard.1962) modified formula (sea water)

[0056]

[0057]

[0058] The growth cycle of autotrophic Chlorella: Lag period: 0-2d; Growth period: 2-8d; Death period: 8-11d.

[0059] Dry matter components in autotrophic Chlorella: protein: 55-67%; crude fiber: 1-4%; lipid: 8-13%; ash: 5-8%; sugar: 10-20%; moisture 3 to 5%.

[0060] Chlorella polysaccharide components: Chlorella polysaccharides contain the following known sugar groups and active monosaccharides. The molar ratio of known sugar groups is as follows: D-fucose: D-rhamnose: D-2-glucosamine: D-galactose: D-glucose=1.3:1.0:1...

Abstract

The invention provides a purification method of chlorella polysaccharide with anti-hepatoma cell proliferation activity, which comprises the following steps: carrying out PCA separation on chlorella crude polysaccharide by combining an ion exchange chromatography method and a phenol sulfuric acid colorimetric method to obtain PCA1, PCA2 and PCA3 crude polysaccharide extract, purifying the extractby combining a molecular exclusion chromatography method and a phenol sulfuric acid colorimetric method to obtain refined PCA1 and refined PCA2, detecting the anti-proliferation effects of the fine PCA1 and the fine PCA2 on SMMC-7721 by using a tetramethylazazolium salt trace enzyme reaction colorimetric method, and detecting the content of sulfate radicals in the refined PCA1 and the refined PCA2through a barium chloride turbidity method. According to the PCA2 obtained by the purification method provided by the invention, the cell proliferation of the SMMC-7721 is obviously reduced by 75.49%after the human hepatoma carcinoma cell SMMC-7721 is intervened for 24 hours at the concentration of 1g / L.

Description

technical field [0001] The present application relates to the technical field of separation and purification of polysaccharides and detection of biological activity, in particular to a purification method of chlorella polysaccharides with anti-proliferation activity of liver cancer cells. Background technique [0002] Chlorella (CV) has been extensively studied in recent years due to its diverse biological functions. Studies have shown that Chlorella (CV) has immunomodulatory, anticholesterol and antitumor activities. [0003] Polysaccharides, the active constituents of chlorella, have been found to have anti-inflammatory and immunomodulatory effects. Chlorella crude polysaccharide extract can induce apoptosis of human liver cancer cells SMMC-7721 by down-regulating anti-apoptotic proteins and up-regulating apoptosis execution proteins, which provides a new idea for the screening of anti-hepatic cancer drugs. However, the specific components in the chlorella crude polysacc...
