Chemo-Taxonomical Classification

• Definition: Chemo-Taxonomical Classification groups plants based on chemical constituents for systematic study.
• Importance: Chemo-Taxonomical Classification aids in identifying plant relationships and medicinal properties.
• This classification is based on the relationship between plant taxonomy and chemical constituents.
• It helps in understanding how plant species in the same family may produce similar types of chemical compounds.

Examples:

• Family: Papaveraceae → Produces alkaloids
  • Papaver somniferum → Morphine (Analgesic)
• Family: Apocynaceae → Produces indole alkaloids
  • Rauwolfia serpentina → Reserpine (Antihypertensive)
  • Catharanthus roseus → Vinblastine (Anticancer)
• Family: Lamiaceae → Produces essential oils
  • Mentha arvensis → Peppermint oil
  • Ocimum sanctum → Holy Basil

Advantages:

• Helps in discovering new medicinal plants from related species.
• Useful for understanding biosynthesis of secondary metabolites.

Disadvantages:

• Requires expertise in botany and chemistry.
• Not practical for general pharmaceutical use.
