Hypericin-like compound

Hypericin-like compound Fagopyrum esculentum (buckwheat) EGF-RTK (PKC)... 

Cmde dried or fresh herb, fresh or dried flowers in olive oil, extracts, tinctures, synthetic hypericin, and so on. Hypericum oil, prepared by maceration of fresh flowers in sunlight for several weeks (usually in olive oil) acquires a red hue usually ascribed to hypericin or lipophilic substituted compounds with a hypericin-like color and fluorescence. Hyperforin is found in freshly macerated oil but is unstable, breaking down within 30-90 days stability can be increased to 6 months in storage by excluding air and using alternate preparation methods. ... 

The pharmacological activity of SJW extracts has recently been reviewed (55-58). Recent reports have shown that the antidepressant activity of Hypericum extracts can be attributed to the phloroglucinol derivative hyperforin (59-62), to the naphthodianthrones hypericin and pseudohypericin (18,63-65), and to several flavonoids (66-69). The role and the mechanisms of action of these different compounds are still a matter of debate. But, taking these previous findings together, it is likely that several constituents are responsible for the clinically observed antidepressant efficacy of SJW.
