Biological Source
Clove, scientifically known as Syzygium aromaticum, is an evergreen tree belonging to the Myrtaceae family. Clove, native to the Maluku Islands in Indonesia, is now cultivated in various tropical regions, including Madagascar, Zanzibar, and Sri Lanka. People derive the spice from the unopened flower buds of the clove tree, harvesting them before the buds fully open.
Chemical Constituents
Clove owes its distinctive aroma and therapeutic properties to its rich chemical composition. Key constituents include:
1. Eugenol: The primary and most abundant compound in cloves, eugenol possesses anti-inflammatory, analgesic, and antimicrobial properties.
2. Acetyleugenol: Another phenolic compound found in clove with similar properties to eugenol.
3. Caryophyllene: A sesquiterpene in cloves with anti-inflammatory and antioxidant effects.
4. Gallic Acid: A phenolic acid contributing to the antioxidant activity of cloves.
5. Tannins: Cloves contain tannins, which have astringent properties and contribute to the herb’s antimicrobial effects.
