Oroxylin A 7-O-beta-D-glucuronide , Oroxylin A Glucoronide
Oroxylin A 7-O-beta-d-glucuronide and wogonoside should also be served as the chemical markers together with baicalin for the quality control of herbs and proprietary traditional Chinese medicine (PTCM) products of radix Scutellariae. Oroxylin A 7-O-glucuronide, Oroxin A, and Oroxin B can bind to the stem region of alpha-hemolysin (alpha-HL), when inhibiting the hemolytic activity of alpha-HL. Oroxylin A 7-O-glucuronide and 4, 5, 7-trihydroxy-6-methoxyflavone at a concentration of 100 microM inhibit 34 and 43% of total prolyl oligopeptidase (POP) activity, respectively.
