It uses the modern and advanced principles, theories, techniques and methods in the field of pharmacognosy and has the necessary knowledge to reach more accurate results. It has the knowledge how to extract, develop and validate analytical methods for sensitive and accurate determination of active ingredients.
COURSE LEARNING OUTCOMES (CLO)
CLO: 1. Learn how to extract active substances or groups of active substances from natural sources.
CLO: 2. Knows about the types of extractors used in the industry.
CLO: 3. Develop a new method for extraction.
NOTE: Practical of the subject shall be designed from time to time on the basis of the above-mentioned theoretical topics and availability of the facilities, e.g. Extraction of the active constituents of crude drugs and chemical tests for their identification. Isolation and separation of active constituents of crude drugs by paper and thin layer chromatography.
Also include the following experiments:
- Determination of Iodine value; Saponification value and unsaponifiable matter; ester value; Acid value.
- Chemical tests for Acacia; Tragacanth; Agar; Starch; Lipids. (castor oil, sesame oil, shark liver oil, bees wax); Gelatin. (Note: A minimum of 10 practicals will be conducted).
