Separation of GPG free from DPG in the manner of the adsorption of the latter on pulpified filter paper (Tab. 1), described in the previous report, is successfully achieved by fractional adsorption (Tab. 2). There is little difference between the properties of GPG thus obtained and of DPG. The optimum pH for the activity to liberate the reducing groups from pectic acid is at 3.6_??_8, slightly lower than the case of DPG. The activity is stable at pH 3.6, and it is lost when pH is not kept 2 and 6 (Fig. 1). The half inactivation of this preparation is observedd when it is kept at 60° for 1 hour at pH 3.6, showing higher stability than DPG (Tab. 3). The fact might be due to the less purity. The activation by salts is similar to DPG (Tab. 4).
