Study Notes
Lecture 8: Medicinal Plants
- Lecture 8 covers the anatomy, dusting powders, taxonomy, physiology, and introduction to pharmacognosy of medicinal plants.
- Lectures 1, 2, 3, 4, 5, 6, and 7 cover anatomy.
- Lecture 8 covers dusting powders.
- A separate lecture covers taxonomy.
- Physiology is covered in a separate lecture (Lecture 6).
- Introduction to pharmacognosy.
Taxonomy
- Taxonomy is the science of describing, naming, and classifying organisms.
- Organisms are grouped based on similarities.
- Scientific names are crucial because common names can vary across regions.
- Latin is the language for scientific classification.
- The hierarchical classification system includes Kingdom, Phylum/Division, Class, Order, Family, Genus, and Species. A mnemonic device is provided, "King Philip Called Out For Good Soup" (KPCOFGS).
Scientific Binomial System
- A two-part naming system (binomial) is used for scientific names.
- The first part is the genus name (always capitalized).
- The second part is the species name (never capitalized).
- Both the genus and species names are italicized in print or underlined if handwritten.
- Example: Ocimum africanum (Genus: Ocimum, Species: africanum).
Family Classification
- A table showing old and new family names is given.
- Labiatae is now known as Lamiaceae.
- Examples of families and their common names are listed: Asteraceae (Sunflower family), Apiaceae (Carrot family), Brassicaceae (Mustard family), Lamiaceae (Mint family), Poaceae (Grass family), and Fabaceae (Bean family).
Scientific Classification of Syzygium aromaticum
- Kingdom: Plantae
- Clade: Tracheophytes
- Clade: Angiosperms
- Clade: Eudicots
- Clade: Rosids
- Order: Myrtales
- Family: Myrtaceae
- Genus: Syzygium
- Species: aromaticum (Author: L.)
- Synonyms are given for the species
Digitalis purpurea and Digitalis lanata
- Digitalis purpurea and Digitalis lanata are examples of plants.
- These plants belong to the genus Digitalis
Identification of Mentha pipperita
- The dried leaves of Mentha pipperita belong to the Lamiaceae family.
- Mentha pipperita is a plant species.
Species Names
- Species names may refer to morphological characteristics, geographical origins, or special indications (e.g., Piper nigrum, Olea europeae, Cannabis indica, Quillaia saponaria).
Plant Classifications
- Two-kingdom classification (Linnaeus, 1758): Animalia and Plantae
- A five-kingdom system (Whittaker, 1970–1980): Animalia, Plantae, Fungi, Protista, and Monera.
Plant Kingdom
- A branching diagram outlining different plant groupings based on characteristics, including those producing seeds.
Angiosperms and Gymnosperms
- Angiosperms (flowering plants) have true flowers or reduced flowers; stems composed of tissues. The ovules and seeds are covered.
- Gymnosperms produce flower-like structures called cones; ovules and seeds are not covered.
Plant Families
- Examples of Monocot families: Gramineae (Poaceae), Zingiberaceae, Liliaceae
- Examples of Dicot families (Umbelliferae (Apiaceae), Solanaceae, Compositae (Asteraceae), Leguminosae (Fabaceae), Lamiaceae
Specific Illustrations of Families and Plants
- Examples of different plants and their families, like Ocimum africanum is part of the Family Lamiaceae.
- Specific examples of monocots and dicots: maize plant and mentha plant.
Quizzes, and Question Items
- A three-part quiz on plant types.
- Part I: Monocot or Dicot Determination
- Part II: Description on Stomata
- Part III: Plant Taxonomy
