| titleOfInvention | The method for improving dihydromyricetin yield in ampelopsis grossdentata |
| abstract | The invention discloses a kind of methods for improving dihydromyricetin yield in ampelopsis grossdentata, and this method is first by ampelopsis grossdentata medicinal material in temperature to toast 1~2h under the conditions of 80~120 DEG C；Crushing obtains ampelopsis grossdentata powder；Ampelopsis grossdentata powder is uniformly mixed with ethyl alcohol again, ultrasonic extraction, filtration obtains dihydromyricetin extracting solution；Dihydromyricetin extracting solution is finally placed in reduced pressure, low temperature environment decentralization cold analysis crystalline substance is placed in, filters drying, filter cake is dihydromyricetin extract.The present invention is significantly higher than dry in the shade sample and common drying sample using the yield of the dihydromyricetin of sample obtained by high temperature drying and processing, both the metabolism less loss of dihydromyricetin had been avoided, extraction cost is greatly reduced again, and it is easy to operate, feasibility is strong, it is a kind of method of efficient, economic extraction dihydromyricetin, the production efficiency of dihydromyricetin can be significantly improved, production cost is reduced, promotes the reasonable utilization of natural resources of Chinese medicinal materials. |
