The marc remains after extraction was dried and then it is extracted with 2 -3 litres of choloroform water (0.25 %) using soxhlet apparatus by continuous hot percolation method. After extraction it was filtered and the removal of solvent was done under reduced pressure by distillation process. The extract was stored in a desiccator.
