Brief introduction to the function of Ganodoran
Ganoderma lucidum on the taxonomic belongs to the Aphyllopho rales Ganodermataceae Ganoderma. Ancient and modern pharmacological and clinical studies have proved that Ganoderma lucidum does have the effect of preventing and curing diseases and prolonging life. Ganodoran has significant pseudo-SOD activity, which can significantly remove free radicals generated by the body, prevent free radical damage to the body, prevent lipid peroxidation, protect cells and delay cell aging. It can improve the body's immunosuppression tumor and enhance the body's ability to resist hypoxia、It regulates blood sugar and blood lipids, protects of liver, prevents radiation and raises white blood cells, anti-herpes virus, anti-mutation, anti-ulcer and so on.
Methods for determining the content of Ganodoran
Here are many methods for determining the content of polysaccharides, such as visible UV spectrophotometry and titration. More reports are currently available on the UV spectrophotometer. The method mainly uses the principle that the polysaccharide reacts with some reagents to determine the linear relationship between the absorbance and the content, According to the different color -developing agents, it can be divided into phenol sulfuric acid method, anthrone sulfuric acid method, salicylic acid method, etc. Liu Yanping used 722 spectrophotometer to measure the absorbance at 625 nm by color -developing agents of anthrone sulfuric acid. The polysaccharide content of Ganoderma lucidum in Ganoderma lucidum cultured by different strains was determined, and the pigment was removed by activated carbon adsorption and removed oligosaccharide by 85% ethanol, basically eliminate interference. Mao Weilun et al. used a 751-GW spectrophotometer and a DV-6l0 spectrophotometer to develop color with an anthrone-sulfate solution. Determination of Ganoderma lucidum polysaccharides in Ganoderma lucidum capsules by determination of absorbance at 625 nm and refluxed two times with 80% acetic acid, Remove oligosaccharide and remove disturbance. Shi Juan et al. used UV-260 spectrophotometer and 752 UV-visible spectrophotometer to determine the content of Ganoderma lucidum polysaccharides at 488.7nm by phenol sulfuric acid colorimetry. Zheng Xiukui et al. determined the content of Ganoderma lucidum polysaccharides in Ganoderma lucidum Capsules at 520 nm with UV-2100 spectrophotometric juice and 3,5-dinitrosalicylic acid colorimetry. Zheng Xuezhen et al. measured the polysaccharide content by UV-2l0O UV-visible spectrophotometric juice and 75lG spectrophotometry. It is reported that the anthrone sulfur method exist disadvantages such as large fluctuations in data and poor repeatability. If through determination conditions in the phenol sulfuric acid method can be studied in detail and find the best conditions, the accuracy and repeatability of the method can be improved. To achieve the purpose of rapid and accurate determination of polysaccharide content of Ganoderma lucidum, the author studied the conditions of determination of Ganoderma lucidum polysaccharide by phenol sulfuric acid method, and made the data of Ganoderma lucidum polysaccharide content determined by modified phenol sulfuric acid method more stable and accurate.
Ganoderma lucidum polysaccharides can be used as a health food in functional foods, and can also be added as food additives to beverages, cakes, and oral liquids, which greatly enrich the food market. This products of our company sells a large in Europe and the United States!
