以大豆卵磷脂、胆固醇为膜材，采用逆相蒸发法制备紫甘薯花青素脂质体，以凝胶柱层析法测定脂质体中紫甘薯花青素的包封率，得出制备紫甘薯花青素脂质体的最优工艺条件为：胆固醇与大豆卵磷脂物质的量比为1：2，紫甘薯花青素水溶液（0.250 mg ·mL-1）与乙醚的体积比为1：4，逆相蒸发时间为30min，上述条件制备的脂质体平均包封率为76.61％。
以大豆卵燐脂、膽固醇為膜材，採用逆相蒸髮法製備紫甘藷花青素脂質體，以凝膠柱層析法測定脂質體中紫甘藷花青素的包封率，得齣製備紫甘藷花青素脂質體的最優工藝條件為：膽固醇與大豆卵燐脂物質的量比為1：2，紫甘藷花青素水溶液（0.250 mg ·mL-1）與乙醚的體積比為1：4，逆相蒸髮時間為30min，上述條件製備的脂質體平均包封率為76.61％。

Purple sweet potatos cyanidine liposomes were prepared by reverse evaporation using soybean lecithin and cholesterol as membrane materials, and the entrapment efficiency of liposomes was determined by gel column chromatography. The results showed that the optimal preparation factor of cyanidine liposomes was as follows:the molar ratio of cholesterol to lecithin was 1:2,the volume ratio of cyanidine solution(0. 250mg·mL-1 )to diethyl ether was 1:4,the time of reduced pressure evaporation was 30min. Under these conditions,entrapment efficiency of cyanidine liposomes was 76. 61%.
