提取纯化制备竹叶黄酮的研究

Study on Extraction Purification and Preparation of Bamboo Leaf Flavonoids

目的:制备符合新资源食品要求的竹叶黄酮。方法:将竹叶先进行优化提取,得到粗制竹叶黄酮,再经大孔吸附树脂柱纯化,得到符合新资源食品要求的竹叶黄酮。结论:竹叶经水提工艺得到的总黄酮总量为9.72%;乙醇提取工艺的总量为12.65%;水提醇沉工艺的总量为16.03%;水提或醇提工艺后,再经大孔吸附树脂柱后总量为24.13%或29.57%,均达到新资源食品要求。

Objective: To prepare bamboo leaf flavonoids which meet the requirements of new resource food. Methods: The bamboo leaves were optimized and extracted, the coarse bamboo leaves were obtained, and then purified by macroporous adsorption resin column, and the bamboo leaf flavonoids were obtained in accordance with the requirements of the new resource food. Conclusion: The content of total flavonoids in bamboo leaves by water extraction process is 9.72%, the content of ethanol extraction process is 12.65%, the process content of water extraction is 16.03%, and the content of water extraction or alcohol extraction process is 24.13% or 29.57% after adsorption of resin column by macroporous, all meet the requirements of new resource food.
