High Purity CGA from Immature Pears by tanga is a document available to read on EtoBox.
This document presents a method for purifying chlorogenic acid (CGA) at high purity from immature pear fruit (Pyrus pyrifolia Nakai). CGA content is much higher in immature pear fruit compared to mature fruit. The method involves extracting CGA from immature pear fruit with 80% methanol, partitioning the extract with ethyl acetate at pH 2.65, purifying the ethyl acetate fraction using Diaion HP-20 column chromatography with water/methanol gradients, and finally purifying CGA using preparative HPLC.
