Medicinal plants contain a wide range of biochemical compounds known as secondary metabolites. These compounds do not directly participate in plant growth, but they play an important role in defending the plant against harmful organisms. These compounds include alkaloids, flavonoids, tannins, essential oils, and glycosides. Each of these compounds has specific therapeutic properties that affect various body functions. Alkaloids, such as morphine, act on the nervous system and are used to relieve pain. Flavonoids function as antioxidants and protect cells from damage caused by free radicals. Tannins have antibacterial properties and help in wound healing. Essential oils possess antimicrobial properties and are used in the treatment of infections. These compounds act by interacting with enzymes and receptors within the body, leading to the regulation of vital processes such as inflammation, blood pressure, and immune response. They also help protect cells from damage and improve organ function. The importance of these compounds is not limited to traditional medicine, but they are also used in the development of modern pharmaceuticals. They are extracted, purified, and used as key components in the pharmaceutical industry. Main types of active compounds in medicinal plants 1. Alkaloids Nitrogen-containing compounds Have strong effects on the nervous system Used in many medicines Examples: Morphine: a powerful pain reliever Quinine: used to treat malaria Atropine: used in ophthalmology Plant sources: Poppy, Belladonna 2. Flavonoids Compounds with antioxidant properties Protect cells from damage caused by free radicals Help strengthen the immune system Functions: Anti-inflammatory Antioxidant Cardioprotective Found in: Tea, citrus fruits, onions 3. Terpenes Aromatic compounds responsible for plant fragrance Major components of essential oils Functions: Antibacterial Antifungal Anti-inflammatory Found in: Mint, thyme, pine 4. Glycosides Compounds consisting of a sugar part and a non-sugar part Affect the heart and circulatory system Example: Digoxin: used to treat heart diseases Found in: Digitalis plant 5. Tannins Compounds with an astringent taste Used in treating diarrhea and wounds Functions: Antibacterial Anti-inflammatory Promote wound healing Found in: Tea, pomegranate, oak 6. Saponins Compounds that produce foam when mixed with water Help reduce cholesterol levels Functions: Anti-inflammatory Enhance immune function Found in: Fenugreek, licorice 7. Essential oils Volatile aromatic compounds Used in medicine and perfumery Functions: Antibacterial Sedative Antifungal Found in: Mint, clove, anise
