Abstract
Способ получения эрихрозида путем экстракции измельченного сырья желтушника левкойного 96%-ным этанолом, упаривания экстракта, последующего перевода остатка в водный раствор, очистки последнего петролейным эфиром, экстракции гликозидов из водного раствора смесью этанол-хлороформ (1:2), упаривания экстракта, растворения остатка в 50%-ном этаноле, очистки этанольного раствора гидроокисью свинца, повторного экстрагирования гликозидов смесью этанол-хлороформ, упаривания хроматографирования на AlOIII степени активности и кристаллизации, отличающийся тем, что, с целью повышения качества целевого продукта, продукт после хроматографирования дополнительно растворяют в метаноле, добавляют н-бутанол при соотношении исходный продукт: н-бутанол 1:(2-5), затем отгоняют метанол, а кристаллизацию осуществляют из н-бутанола при 70-90C.The method of obtaining eryhrozide by extracting crushed raw material of the levkusnaya jaundice with 96% ethanol, evaporation of the extract, subsequent transfer of the residue into an aqueous solution, purification of the latter with petroleum ether, extraction of glycosides from an aqueous solution with ethanol-chloroform (1: 2), evaporation of the extract, dissolution in 50% ethanol, purifying the ethanol solution with lead hydroxide, re-extracting glycosides with ethanol-chloroform, evaporating the chromatography on an AlOIII degree of activity and crystallization; In order to improve the quality of the target product, the product after chromatography is additionally dissolved in methanol, n-butanol is added at a ratio of starting product: n-butanol 1: (2-5), then methanol is distilled off, and crystallization is carried out from n- butanol at 70-90C.
