Hypericum perforatum L., traditionally called St. John�s Wort has been used for decades as a phyto-therapeutic herb due to antidepressant, antimicrobial and antiseptic properties. As a result, the presented study evaluates the influence of the harvesting season for the Hypericum perforatum L. plant material, which is crucial for obtaining significant amounts of active principles.
St. John s Wort (SJW) or Hypericum perforatum L. is a therapeutic plant highly used in pharmacology. Recent in vivo anti-cancer action of naphtodianthrones (NTs) has extended the research related to enrichment methodologies of SJW phyto-extracts. Therefore, the presented study pursuits the optimization of single-step extraction methodologies to obtain NTs-rich extracts from SJW.
