Shinoda

The Shinoda test is a chemical procedure used to identify the presence of flavonoids, a group of compounds found in many plants. It involves adding magnesium and hydrochloric acid to a plant extract; if flavonoids are present, the mixture produces a characteristic colored solution, usually red, pink, or purple. This test helps researchers and scientists quickly determine whether certain plants contain flavonoids, which are known for their antioxidant and health-promoting properties. It is a simple, qualitative method often used in phytochemical studies to screen plant materials for specific bioactive compounds.
