The moisture content of dry powder of leaves
of P. granatum L. was 8.3% which is not very high, hence
it would discourage bacteria, fungi or yeast growth. The
ash value was determined by three different forms viz.,
total ash, acid insoluble ash and water soluble ash.The
total ash is particularly important in the evaluation of purity
of drugs; i.e. the presence or absence of foreign inorganic
matter such as metallic salts or silica.
