Phytopharmacy & Phytomedicine — Phase 1

Plant Material Selection & Botanical Authentication

The first phase of phytopharmaceutical research establishes the scientific foundation upon which subsequent extraction, screening, and formulation work depends: correct selection of the plant part to be studied and rigorous authentication of its botanical identity. Because phytoconstituent yield and biological activity vary markedly between plant parts and can be confounded by adulteration or misidentification, this phase covers the concept and classification of medicinal plants, the rationale for plant part selection, the macroscopic, microscopic, molecular, and chemical methods used to authenticate raw material, and the collection, herbarium deposition, and storage practices that safeguard material integrity.
