Antioxidative Activity of Hop Bitter Acids and Their Analogues
Bioscience, Biotechnology, and Biochemistry, 1995 Hop bitter acids, humulones (1) and lupulones (2), were shown to have potent DPPH radical scavenging activity (RSA) and lipid peroxidation inhibitory activity (LIA). Furthermore, 5-acetyl lupulones (3) and 4-methyl lupulones (4) had more potent LIA than native lupulones but no RSA.
