[0077] Example 2. Polysaccharide fingerprint analysis of Ganoderma lucidum spore powder sample from a certain place in Shandong

[0078] 1. Extraction of Ganoderma lucidum spore powder polysaccharide

[0079] Accurately weigh 700 mg of the wall-broken Ganoderma lucidum spore powder sample into a 50 mL centrifuge tube, add 30 mL of ultrapure water, sonicate it in a water bath at 60°C for 60 minutes (power 300 watts), and centrifuge after cooling. The residue is washed with a small amount of ultrapure water and centrifuged. The two supernatants were combined, and the ultrapure water was dialyzed for 12 hours, and after concentration under vacuum at 60°C, the ultrapure water was added to make the volume up to 5 mL as the crude polysaccharide aqueous solution for testing.

Abstract

The invention relates to a construction method of ganoderma spore powder polysaccharide fingerprint and a standard fingerprint of the ganoderma spore powder polysaccharide, belonging to the fingerprint technical field of the traditional Chinese medicine and products thereof and the functional food raw material and products thereof. The construction method in the invention comprises the following steps: extracting ganoderma spore powder polysaccharide; hydrolyzing a part of ganoderma polysaccharide; performing PMP derivatizing reaction on a part of the hydrolyzate of ganoderma polysaccharide; performing reversed phase HPLC fingerprint analysis and determining the standard fingerprint; performing the HPLC analysis on the polysaccharide fractions of ganoderma spore powder samples from fifteen different producing areas and comparing the fingerprints of the ganoderma spore powder samples to determine the common fingerprint characteristics so as to obtain a standard fingerprint. The fingerprint has nineteen common peaks in all, the sum of the peak areas of the common peaks accounts for 98% of the total peak area, and the peak area of each of four fingerprint peaks is more than 5% of the total peak area. The method in the invention is stable, has high degree of precision and good repeatability and is easy to grasp; and the quality situation and producing area of the ganoderma spore powder polysaccharide can be grasped from the overall characteristic of the chromatography, and a new scientific method for the quality control and identification of ganoderma spore powder can be provided.

Description

technical field [0001] The invention relates to a method for establishing the HPLC fingerprint of the ganoderma spore powder polysaccharide, and also relates to the standard fingerprint of the ganoderma spore powder polysaccharide obtained by the method. The invention belongs to the technical field of fingerprints of traditional Chinese medicine and its products, functional food raw materials and its products. Background technique [0002] Ganoderma lucidum is a fungus belonging to the Phylum Fungi, Class Basidiomycetes, Polyporaceae, Ganodermaceae, and the genus Ganoderma. Chinese Pharmacopoeia stipulates that Ganoderma lucidum can be used as medicine [ Ganoderma lucidum ( Leyss.ex Fr. ) Karst .] and Zizhi ( Ganoderma sinense Zhao, Xu et Zhang ); Ganoderma lucidum varieties that can be used in health food announced by the State Food and Drug Administration include red lucidum, purple lucidum and Songshan Ganoderma ( Ganoderma tsugae Murr). Ganoderma lucidum spore...
