SpSsob přípravy D-erytrózy /U-14C/ z rádioaktívneho polysacharidu /U-* 1^/ a jejp-nitro-fenylhydrazónu 1Process for the preparation of D-erythrose (U-14C) from the radioactive polysaccharide (U- * 1) and its p-nitro-phenylhydrazone 1
Vynález sa týká spósobu přípravy D-erytrózy /U-^C/ z rádioaktívneho polysacharidua 0ej p-nitro-fenylhydrazónu.The invention relates to a process for the preparation of D-erythrose (U-C) from the radioactive polysaccharide and p-nitro-phenylhydrazone.
Vodorozpustný rédioaktivny polysecharid typu oC /1 —* 4/ glukénu větveného oC/1—'6/vazbami získaný v procese komplexného sprscovania radioaktivněj biomasy zelených alebomodrozelených rias kultivovaných v prostředí ^^C02 /Cel. patent 121 808/ je vhodnou su-rovinou na přípravu vzácných cukrov.The water-soluble oC / 1 44 / glucan-type polycyclic polysecharide branched by bamiC / 66 / bonds obtained in the process of complex scoring of the radioactive biomass of green or non-biodegraded algae cultured in the ^^C02 / Cel medium. Patent 121,808 / is a suitable substrate for the preparation of rare sugars.
Podstata vynálezu spočívá v přípravě D-erytrózy /U-^^C/ resp. jej p-N02-fenylhydra-zónu z rádioaktívneho biologického materiálu a výhodou zo zelených, resp. modrozelenýchrias tak, že hydrolyzát získaný z vodorozpustného polysacharidu /U-^^C/ typu oc /1 —— 4/glukánu účinkom minerálnych kyselin alebo enzýmu glukoamylázy sa podrobí oxidatívnemuodbúraniu octanom olovičitým. D-erytróza /U-^C/ sa izoluje z reakčného prostredia vovýtažku cca 50 % a pósobením p-nitrofenylhydrazínu sa prevedie na stabilný p-nitrofenyl-hydrazon D-erytrózy /U-^^C/. Výhodou navrhovaného spósobu přípravy D-erytrózy /U-^^C/ je jeho jednoduchost, nízképracovné náklady a možnost prechovávania D-erytrózy /U-^C/ vo formě jej stabilného hy-drazónu. D-erytróza /U-^^C/ je dóležitá látka pri biochemickom výskume a pri štúdiuchémie sacharidov. 201 336SUMMARY OF THE INVENTION The present invention is based on the preparation of D-erythrose (U -? - C) and the? its p-NO 2 -phenylhydrazone from the radioactive biological material, and preferably from green, respectively. the blue-green so that the hydrolyzate obtained from the water-soluble polysaccharide (U -? - C) of the type? 1/4 / glucan by the action of mineral acids or the enzyme glucoamylase is subjected to lead acetate oxidation degradation. D-erythrose (U-C) is recovered from the reaction medium at a rate of about 50% and is converted to stable β-nitrophenyl hydrazone D-erythrose (U U-C^ C) by p-nitrophenylhydrazine. The advantage of the proposed method for the preparation of D-erythrose (U-2-C) is its simplicity, low labor costs and the possibility of storing D-erythrose (U-C) in the form of its stable hydrazone. D-erythrosis / U-^ C / is an important substance in biochemical research and carbohydrate study. 201 336
