Extraction method of acanthopanax senticosus anthocyanin

The invention discloses an extraction method of acanthopanax senticosus anthocyanin. The extraction method comprises the following steps: taking non-lignified purple tender shoots of an acanthopanax senticosus plant, drying and crushing to obtain acanthopanax senticosus powder; regulating the pH value of an ethanol aqueous solution with a volume concentration of 60% to be 3 +/- 0.5, and taking theethanol aqueous solution as an extraction solvent; adding the extraction solvent into the acanthopanax senticosus powder, and then carrying out ultrasonic extraction under a water bath condition; andafter the ultrasonic extraction is finished, cooling to room temperature, and centrifuging to obtain the supernatant containing acanthopanax senticosus anthocyanin. A new anthocyanin source is obtained. 本发明公开了一种紫五加花青素的提取方法，包括以下步骤：取紫五加植物未木质化的紫色嫩梢部位，干燥、粉碎，得紫五加粉末；将体积浓度为60％的乙醇水溶液调节pH为3±0.5，作为提取溶剂；在紫五加粉末中加入提取溶剂，然后水浴条件下超声提取；超声提取结束后，冷却至室温，离心，所得上清液中含有紫五加花青素。本发明获得了一种新的花青素来源的新资源。
