METHOD OF PRODUCING BIOLOGICALLY ACTIVE PECTIN

摘要

FIELD: chemistry.SUBSTANCE: invention relates to production of polysaccharides from plant material. The method involves extracting the material with a threefold amount of 1% ammonium oxalate solution for 1.5 hours on a boiling water bath three times. The material used is oil cake obtained after separating flavonoids from common tansy flowers. The obtained extracts are mixed, filtered through several layers of gauze and pectins are precipitated in the filtrate with threefold excess 96% ethyl alcohol. The obtained precipitate is then washed successively with 96% ethyl alcohol, acetone and ether and dried over concentrated sulphurica acid.EFFECT: invention enables to obtain biologically active pectin with anti-inflammatory action.
