Secondary metabolites of Hypericum confertum and their possible chemotaxonomic significance.
    Natural product communications, 2010, Volume: 5, Issue:6

    The phloroglucinol derivative hyperforin, the naphthodianthrones hypericin and pseudohypericin, the phenylpropane chlorogenic acid, and the flavonoids rutin, hyperoside, apigenin-7-O-glucoside, kaempferol, quercitrin, quercetin and amentoflavone were investigated in Hypericum confertum growing wild in Turkey. After drying at room temperature, the plant materials were assayed for secondary metabolite concentrations by HPLC. All the listed compounds were detected at various levels. This is the first report on the chemistry of H. confertum.

Chemical constituents of Hypericum adenotrichum Spach, an endemic Turkish species.
    Natural product research, 2009, Volume: 23, Issue:13

    The present study was conducted out to determine hyperforin, hypericin, pseudohypericin, chlorogenic acid, rutin, hyperoside, quercitrin, quercetin, kaempferol, apigenin-7-O-glucoside and amentoflavone contents of Hypericum adenotrichum, an endemic plant species to Turkey. The aerial parts representing a total of 30 individuals were collected at full flowering, dried at room temperature and assayed for secondary metabolite concentrations by HPLC. All of the chemicals were detected at various levels except for hyperforin. This is the first report on polar chemistry of this endemic species.

    Topics: Anthracenes; Bridged Bicyclo Compounds; Chromatography, High Pressure Liquid; Hypericum; Kaempferols; Perylene; Phloroglucinol; Quercetin; Terpenes; Turkey

Effects of two different extracts of St. John's wort and some of their constituents on cytochrome P450 activities in rat liver microsomes.
    Pharmacopsychiatry, 2001, Volume: 34 Suppl 1

    We examined two commercially available St. John's wort extracts and some of their constituents for their potential in inducing rat cytochrome P450 (CYP450) enzyme activities after oral administration. None of the extracts or pure constituents tested enhanced the hepatic cytochrome content or the activity of cytochrome P450 isozymes in rat liver microsomes. Our results demonstrated that the reported interactions between St. John's Wort and various other drugs are not mediated by CYP 450 isoforms present in rat liver.
