Chemo-Taxonomical Classification

  • This Chemo-Taxonomical 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 of Chemo-Taxonomical

  • Requires expertise in botany and chemistry.

  • Not practical for general pharmaceutical use.
