THE DEVELOPMENT OF TECHNOLOGY FOR OBTAINING OF TENESTROL SUBSTANCE OF ESTROGENIC AC-TION FROM THE AERIAL PARTS OF FERULA TENUISECTA
Abstract
Extraction of the sum of esters of the sesquiterpene alcohols from the aerial part of Ferula tenuisecta and purification of obtained extract were studied, allowing in following to get the final substance without green coloration. It was determined the optimum adsorbent – actuated coal and its amount for removing the green coloration of water-alcohol extract from used raw materials. It was found that for the purification of the bottoms of water-alcohol extract, five-fold treatment with extractive petrol in a volume ratio of water solution – solvent 2:1 is necessary, and for extraction esters from a purified water solution – three-fold extraction with ethyl acetate in a volume ratio of water solution – solvent 2:1.
It was used a filler to effective drying the substance of Tenestrol. The microcrystalline cellulose in a weight ratio from 1:8 to 1:10 to the raw material was chosen as the optimum filler.
Technology for obtain of substance of esters of sesquiterpene alcohols with estrogenic action from the aerial part of Ferula tenuisecta was developed and called “Tenestrol”. From this technology substance "Tenestrol" with yield of 3.8% by weight of the raw material is obtained, which contains not less 20% of the esters.
