Study Notes
Evaluation of Crude Drugs
- 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
- Adulterations and substitutions
Types of Evaluation
- There are three types of evaluation:
- Organoleptic evaluation
- Biological evaluation
- Chemical evaluation
Organoleptic Evaluation
- Organoleptic evaluation means the study of drugs using organs of senses.
- It refers to the methods of analysis using:
- Colour
- Odour
- Taste
- Size
- Shape
- Special features, such as:
- Touch
- Texture
