Microscope by the virtue of its property to magnify, permits minute sections under study to enlarge so that, leaf constants, stomatal index, palisade ratio can be determined.
Physical evaluation
These are rarely constant for crude drugs, but may help in evaluation with reference to moisture content, specific gravity, density, optic rotation, refractive index, melting point, viscosity, solubility etc.
Chemical evaluation
It compromises of different chemical test and assays. The isolation, purification and identification of active constituents are the methods of evaluation. Quantitative chemical test such as acid value, saponification value etc are also covered under these techniques.
Biological evaluation
When the estimation of potency of crude drug or its preparations are done by means of measuring its effect on living organisms like bacteria, fungal growth, or animal tissue, it is known as biological effect of the drug, compared to the standard drug.
By these methods a crude drug can be assessed and further clinical trial can be recommended
