Problems solved by technology

The research on Ganoderma tsugae Murrill. is rarely reported. Among them, only in 2003, Taiwan International Famous University declared the title "Polysaccharide-based extract from ganoderma, pharmaceutical use thereof, and process for preparing the same" in the United States. The patent discloses a process for obtaining the water-soluble crude extract of Pinus fir Ganoderma lucidum, but this process only involves steps such as water extraction, alcohol precipitation and deproteinization, and the obtained product is the primary crude product of Pinus fir Ganoderma lucidum

Abstract

The present invention discloses Ganoderma tsugae proteoglycan and its preparation process and application. The Ganoderma tsugae proteoglycan is prepared with Ganoderma tsugae sporophore, and has average molecular weight of 5-16 KDa. The Ganoderma tsugae proteoglycan consists of protein and polysaccharide in the weight ratio of 15.5-19.5 to 80-86. The polysaccharide consists of galactose, glucose, mannose and fructose in the proportion of 1.60-1.75 to 1.00 to 0.15-0.22 to 0.10-0.20, and has beta(1-->3) connected main chain. The Ganoderma tsugae proteoglycan of the present invention has obvious effects of inhibiting tumor and raising immunity and thus high medicinal value.

Description

technical field [0001] The invention relates to a proteoglycan and its preparation method and application, in particular to a proteoglycan obtained from Ganoderma tsugae Murrill., an extraction method thereof and the application of the proteoglycan as an active ingredient of a medicine. Background technique [0002] At present, there are three main ways to treat tumor diseases clinically: surgery, radiotherapy and chemotherapy. However, radiotherapy and chemotherapy seriously damage the normal cells and tissues of the human body, causing many patients to decline rapidly, and even cannot continue treatment. For a long time, people have been looking for new anticancer drugs with the characteristics of low toxicity and high tumor inhibition rate. Since the occurrence and spread of tumors are closely related to the immune function of the human body, tumor immunotherapy has been developed. In the middle and late twentieth century, some polysaccharide drugs derived from fungi wer...
