ABSTRACT
According to Erdelmeier, acylphloroglucinols are found in fresh herbs of H. perforatum.1 The main acylphloroglucinol is hyperforin and is highly lipophilic, very photo-and oxygen-labile compound (Fig. 11.1). When exposed to air and light, hyperforin degrades rapidly. Hyperforin is soluble in DMSO and organic solvents.
