Unit 1
Metabolic Pathways and Biogenesis of Secondary Metabolites
Unit 1 covers key metabolic pathways in higher plants like the shikimic acid, acetate, and amino acid pathways, explaining the formation of secondary metabolites and the use of radioactive isotopes in biogenetic studies.

Unit 2
Secondary Metabolites: Classification, Sources and Applications
This unit explores various classes of secondary metabolites including alkaloids, flavonoids, steroids, glycosides, volatile oils, tannins, resins, and terpenoids, detailing their sources, chemistry, uses, and commercial applications.

Unit 3
Isolation, Identification of Key Phytoconstituents
Unit 3 covers the isolation, identification, and analysis of important phytoconstituents such as terpenoids (menthol, citral, artemisin), glycosides (glycyrrhetinic acid, rutin), alkaloids (atropine, quinine, reserpine, caffeine), and resins.

Unit 4
Industrial Production of Essential Phytoconstituents
Unit 4 focuses on the industrial production, estimation, and therapeutic applications of key phytoconstituents like forskolin, sennoside, artemisinin, digoxin, taxol, vincristine, atropine, and caffeine.
Unit 5
Modern Extraction Techniques
This unit introduces modern phytochemical techniques including advanced extraction methods and the use of spectroscopy, chromatography, and electrophoresis for isolation, purification, and identification of crude drugs.
