【摘要】 银杏叶黄酮类化合物具有很高的保健和药用价值。采用微波萃取银杏叶黄酮类化合物,与传统溶剂萃取黄酮类化合物方法相比,微波萃取法更简单,而且具有萃取时间短,成本低,萃取效率高等优点。该法适用面更广,能大大提高提取物中黄酮类化合物含量,且溶剂损耗较少。微波辐射5min后抽提1.5h就可以得到较好的效果,而且利用微波处理,在短时间内抽提的提取率按鲜银杏叶重计可达到0.536%,这是传统工艺提取率的2.2倍。更多还原

【Abstract】 Ginkgo biloba flavone glycosides have high values of health care and drug. They are extracted by microwave . Compared with traditional solvent extraction, this method is simpler and have some advantages of less time, lower cost, higher extractive ratio. This method can be used in wider fields, enhances greatly the content of flavone and saves solvent. The results is excellent within only 5 min by microwave radiation and 1.5 h by extraction. The extractive ratio can reach 0.536 % weight of the fresh ginkgo leaves which is 2.2 times of traditional method.更多还原
