Yolk Creosote Concocted A New Technology Research,

The egg tar is takes boils thoroughly the egg-yolk, heats up obtains brown or the vandyckbrown oily liquid. This experiment has mainly conducted following five aspects research.First, conducts the research to the egg tar tradition preparation craft. Take the oil extractionrate as the target, inspected the firepower and whether closes tightly to the dry distillation lawpreparation egg tar oil extraction rate influence. Suggestion when use dry distillation lawpreparation egg tar, uses the high heat airtight dry distillation for to be suitable.Next, take the egg tar as the research object, Uses the Silica gel column chromat-ography lawand TLC separation obtains harman, And uses TLC, HPLC and so on has carded on the appraisal toit.The egg tar prepares the new craft research, First used the single factor method to the egg-yolkdrying time, The egg-yolk heats up to the different temperature of ignition reduced pressure and soon has carried on the inspection, Uses the orthogonal experiment to design the law selection bestcraft. Then we distilled the new craft preparation to the reduced pressurethe and the commonly usedtraditional dry distillation law and the chloroform extraction process preparation have conducted thecomparison research. Further had proven the reduced pressure distills the new craftpreparation in toenhance the oil extraction rate in the foundation,had achieved "Reduces the toxicity andIncrease the effect" the goal.Has formulated in for the first time the egg tar harman and the Benzo(α)pyrene HPLC contentdetermination method. Method operation simple, result stable accurate, reappears the nature to begood, for enhanced the egg tar the quality specification to provide the basis.The egg tar is kind of commonly used Chinese native medicine until now has not actuallysuited clinical utilization the dosage-form, brings enormous incon-venient for theactual utilization.Therefore we use o/w the method has separately prepared the different content egg tar breast, andconducted the quality appraisal research to it, the result has conformed to the related standard.
