一种从火龙果皮提取原花青素的方法
摘要：
一种从火龙果皮提取原花青素的方法，以火龙果皮为主要原料，采用酶制剂结合溶剂提取原花青素。制备方法包括以下步骤：备料、配制缓冲溶浓、配制酶液、投料、酶解、提取、纯化和真空干燥。利用本发明的方法制备的原花青素，产品安全性好、质量佳，酶制剂的用量少，该精制品中含有的原花青素为儿茶素、表儿茶素和二聚体，且原花青素纯度为96.7%。
摘要（英）：

The invention provides a method for extracting procyanidins (OPC) from pitaya peels. The OPC is extracted by using the pitaya peels as the main raw materials and combining an enzymic preparation with a solvent. The preparation method comprises the following steps: material preparation, buffer solution preparation, enzyme liquid preparation, feeding, enzymolysis, extraction, purification and vacuum drying. The OPC prepared by utilizing the method has good product safety and quality and small amount of the enzymic preparation. The OPC contained in refined products is catechin, epicatechin and a dimer and has purity of 96.7%.
