Evaluation of Crude Drugs
INTRODUCTION
Evaluation of a drug ensures the identity of a drug and
determines the quality and purity of drugs. The main reasons behind the need
for evaluation of crude drugs are biochemical variation in the drug, effect of
treatment and storage of drugs, and the adulterations and substitutions.
Improvements in analytical methods have definitely led to
improvements in harvesting schedules, cultivation techniques, storage,
activity, stability of active compounds, and product purity. All of these gains
have resulted in tre-mendous improvements in the quality of herbal
prepara-tions now available.
Methods currently employed in evaluating herbs are
organoleptic, microscopic, physical, chemical, and biological parameters.
