Abstract
Verectin antiserum raised in white rabbits was immunoprecipitated with the Aloe vera nondialysable fraction. Analysis of the immunoprecipitation revealed that verectin
accounted for about 1.25% of the total proteins in the nondialysable fraction of Aloe vera gel. The verectin antibody showed differential immunoreactivities against nondialysable
fractions of A. arborescens, A. chinensis, and A. vera: 1) an immunopreciptin line was formed against the fraction of A. vera, but not against those of A. arborescens and A. chinensis gel in an Ouchterlony double immunodiffusion test and 2) an immunopositive band was
detected in the A. vera and A. chinensis nondialysable fractions but not in that of A. arborescens in immunoblotting. These findings indicate that the verectin antibody can be used
to distinguish Aloe materials.
