[ 1 ] - Population Variability of Main Secondary Metabolites in Hypericum lydium Boiss. (Hypericaceae)(2015 summer)
In the present study, we investigated the variation in the content of naphthodianthrones hypericin and pseudohypericin, phloroglucinol derivatives hyperforin and adhyperforin, the phenolic acids as chlorogenic acid, neochlorogenic acid, 2,4-dihydroxybenzoic acid, and the flavonols, namely, hyperoside, isoquercitrin, quercitrin, quercetin, avicularin, rutin, (+)-catechin and (-)-epicatechin, and...

[ 3 ] - Modeling the Altitudinal Variation in Secondary Metabolite Contents of Hypericum Orientale from Turkey
In the present study, models were developed to estimate the altitudinal variation in secondary metabolite contents of Hypericum orientale growing wild in “Güldağı” mountain, Turkey. Aerial parts of flowering 30 individuals were collected at six different altitudes (500, 1150, 1650, 2100, 2720 and 3250 m). Actual secondary metabolite contents of plants were measured by High Performance Liquid Ch...
