ABSTRACT
Four known flavones, 5-hydroxyauranetin, araneosol, calycopterin and sarothrin, were isolated from the aerial parts of Herissantia tiubae. (K. Schum) Brizicky (Malvaceae). Their structures were identified by the use of spectroscopic methods such as IR, UV, and mainly nuclear magnetic resonance, which included two-dimensional techniques (1H-1H COSY, NOESY, HETCOR, and HMBC). This is the first reported isolation of these compounds from the genus Herissantia..
