Imperata cylindrica, commonly known as cogongrass or Japanese blood grass, is a perennial rhizomatous plant widely distributed in tropical and subtropical regions. It is primarily cultivated for its bioactive compounds, particularly flavonoids like imperatorin and cycloaromatin, extracted via solvent extraction or supercritical fluid technology. The botanical source serves as a raw material for natural product isolation rather than a synthetic chemical with a single defined molecular formula.
Raw extracts may cause skin irritation; personal protective equipment (PPE) is required during handling. Storage must be in cool, dry conditions away from direct sunlight to prevent degradation of active constituents. Not approved for human consumption without standardized pharmaceutical processing.
