METHOD FOR PRODUCTION OF WATER-SOLUBLE POLYSACCHARIDES FROM PLANTS

摘要

FIELD: agriculture. ^ SUBSTANCE: seeds of plants such as knot grass are treated with an ultradispersion ferric powder prior to seeding. The plants having grown from the seeds are collected and dried in a dryer cabinet at a temperature of 30-35 during 1-3 days. The dried grass, together with inflorescences and seeds if any, is sorted out; stalks are removed and discarded while the above-ground parts are treated with ether in a Soxlet apparatus. Then water-soluble polysaccharides are extracted in accordance with the 1:30 raw material-water ratio conditions and ethanol-precipitated; based on the weight of the powder yielded one concludes on accumulation and increase of polysaccharides. ^ EFFECT: plant seeds pre-planting treatment enables improvement of the plant's nutritive and curative properties. ^ 2 cl, 1 tbl, 1 ex
