摘　　要：以杨梅果实为原料,采用微滤-树脂联用技术分离提取杨梅红色素,研究微滤-树脂技术分离提取的最佳工艺。结果表明,在无机陶瓷膜平均孔径0.2μm,操作压差0.10MPa,膜面流速2500L/h条件下能快速分离提取杨梅红色素,微滤液经D101-A树脂吸附后用75%乙醇洗脱、浓缩蒸发、干燥,可得到高纯度的杨梅红色素产品。A red pigment was extracted from Mynica esculenta Buch-Ham by combinatorial microfdtration and resin column chromatography. Meanwhile, the optimal extraction process for combinatorial microfdtration and resin column chromatography was also investigated. Results indicated that 0.2 μm of pore size in ceramic membrane, 0.10 MPa of membrane pressure, and 2500 L/h of cross-flow velocity could provide an effective separation of the red pigment. The separated red pigment was absorbed by D101-A resin when the filtrate passed through D101-A resin column. The red pigment on resin column was successfully eluted with 75% alcohol. The red pigment with high quality was obtained after condensation and drying.
