The invention discloses a preparation method of polysaccharide in pine cone from Pinus koraiensis, relating to a preparation method of polysaccharide in pine cone from Pinus koraiensis. The invention solves the problems that the traditional preparation method of the polysaccharide in pine cone from Pinus koraiensis cannot completely remove chemical components with weak polarity and medium polarity in the pine cone from Pinus koraiensis and the protein removal rate is relatively lower. The preparation method comprises the following steps: 1. degreasing; 2. extracting; 3. preparing coarse polysaccharide; 4. deproteinizing; and 5. decoloring, collecting precipitates, freezing and drying to obtain the refined polysaccharide in pine cone from Pinus koraiensis. The extraction rate of the neutral polysaccharide in pine cone from Pinus koraiensis prepared by the invention can reach 1.15-1.52 percent, the protein removal rate is up to over 70 percent and the pigment removal rate is up to over 95 percent. The chromatography test shows that the neutral polysaccharide mainly comprises seven monosaccharides, namely D-ribose, L-rhamnose, L-arabinose, D-xylose, D-mannose, D-glucose and D-galactose, and the preparation method of polysaccharide in pine cone from Pinus koraiensis is applied to the field of preparation of neutral polysaccharide pine cone from Pinus koraiensis.

Method for cultivating Korean pine planted forest

The invention discloses a method for cultivating a Korean pine planted forest. From the aspect of site conditions, in the slope direction aspect, Korean pines require shade slopes, and the gradient is preferably within 10-20cm, the initial planting density in districts with good site conditions can be 4000 Korean pines, the initial planting density in districts with poor site conditions can be 3000 Korean pines, the line spacing can be 2-3m, the canopy density can reach about 0.8 according to the forest, whether mingling broad-leaf species influence growth of the Korean pines or not is comprehensively considered, the intensity of intermediate cutting is 20% the number of the Korean pines, broadleaf trees are reserved, and it is determined by reserving about 0.4 canopy density on the side portions of the Korean pines. At the beginning of May, the mixture of pine tar and diesel oil with the ratio being 1:1, or the mixture of pine tar and gasoline with the ratio being 1:1 or pine tar raw liquid is used for conducting dry painting treatment. Mountainy nursery of the Korean pines can be achieved, and the history that seedling culture of the Korean pines can only be achieved in the flat ground is ended. Mountainy seedlings are high in yield and good in quality, and the cost of the mountainy seedlings is lower than the cost of flat ground seedlings.

Two-dimensional multi-channel chromatographic system and method for separating and screening strong antioxidant components of pinus koraiensis pinecone extract by using same

The invention discloses a two-dimensional multi-channel chromatographic system and a method for separating and screening strong antioxidant components of a pinus koraiensis pinecone extract by using the same, and relates to a chromatographic system and a method for separating and enriching pinecone polyphenol by using the same. According to the system and the method, a novel two-dimensional multi-channel chromatographic system is combined with macrooprous resin for separating and screening the strong antioxidant components of the pinecone polyphenol. The two-dimensional multi-channel chromatographic system is characterized in that a chromatographic column is partitioned into an absorbing column and separating columns, so as to enable a polyphenol compound to be effectively and rapidly separated, and one absorbing column and a plurality of separating columns are adopted for achieving relatively effective separation. Compared with the single-column chromatograph, the two-dimensional multi-channel chromatographic system has the advantages that the polyphenol can be more effectively and rapidly separated, the separating speed can be remarkably increased by a plurality of times even about ten times, the separating efficiency can be remarkably improved by a plurality of times even about ten times, and functional components can be rapidly screened through combining with measurement of antioxidant indexes.
