Abstract

The conversion from kobophenol A into carasinol B, two main chemicalconstituents of Caragana sinica, was confirmed by in vitro acid-catalyzed epimerization.The result provides important information about the biotransformation of kobophenol A inplants and its metabolism in rats.
Keywords: Kobophenol A; carasinol B; Caragana sinica. Kobophenol A; carasinol B; Caragana sinica.
