| titleOfInvention | A kind of method that kynurenine is prepared from Chinese horseshoe crab tail |
| abstract | The invention discloses a kind of method for preparing kynurenine from Chinese horseshoe crab tail, comprise the following steps：Step 1: the preparation of Chinese horseshoe crab caudal style powder；Step 2: the preparation of Chinese horseshoe crab tail runic thing；Step 3: the initial gross separation purifying of Chinese horseshoe crab tail runic thing；Step 5: component A8's isolates and purifies；Step 6: component A8's 24 isolates and purifies：After taking component A8 24 to add methanol dissolving in right amount, positive post separation is crossed；Sample 50mg is taken to mix sample with 150mg silica whites, 5g silica gel after sample upper prop, is eluted with petroleum ether and acetone with column is filled after petroleum ether saturation, collects petroleum ether：Acetone=1:Cut when 10, totally 60 pipe, merges 25 pipes to 40 pipes, is concentrated under reduced pressure after merging cut, after solvent evaporated, kynurenine is made.The present invention has isolated kynurenine from Chinese horseshoe crab tail first, active ingredient of the kynurenine as China's horseshoe crab tail, and the secondary development for Chinese horseshoe crab tail is significant. |
