Secondary metabolites of Hypericum scabrum and Hypericum bupleuroides
(Taylor & Francis Ltd, 2009)
The genus Hypericum (Guttiferae) is a source of biologically active secondary metabolites, notably hyperforin, hypericins and various phenolics. In the present study the presence of the phloroglucinol derivative hyperforin, ...
Phenological changes in the chemical content of wild and greenhouse-grown Hypericum pruinatum: flavonoids
(Tubitak Scientific & Technical Research Council Turkey, 2014)
The present study was conducted to determine the phenological changes in the content of main flavonoids, namely amentoflavone, hyperoside, isoquercitrin, quercitrin, quercetin, avicularin, rutin, (+)-catechin, and ...
Secondary Metabolites of Hypericum leptophyllum Hochst., an Endemic Turkish Species
(Hindawi Ltd, 2012)
In the present study, the presence of the phloroglucinol derivative hyperforin, the naphthodianthrones hypericin and pseudohypericin, the phenylpropane chlorogenic acid and the flavonoids rutin, hyperoside, kaempferol, ...
Factors affecting the variation of bioactive compounds in Hypericum species
(Akademiai Kiado Zrt, 2019)
The genus Hypericum (Hypericaceae) consists of 484 species from 36 sections with worldwide distribution in different areas. Turkey is considered as hot spot for diversity of Hypericum genus. Despite numerous publications, ...
Chemical composition of Hypericum species from the Taeniocarpium and Drosanthe sections
(Springer Wien, 2014)
The presence of several phytochemicals, namely naphthodianthrones hypericin and pseudohypericin, phloroglucinol derivatives hyperforin and adhyperforin, the phenolic acids as chlorogenic acid, neochlorogenic acid, caffeic ...
The quantitative effect of temperature and light intensity at growth in Origanum onites L.
(Academic Journals, 2010)
The study was aimed to define the relationships between temperature, light intensity and growth parameters. Namely, net assimilation rate, relative growth rate, leaf weight ratio, leaf area ratio and specific leaf area for ...
Variation of Bioactive Secondary Metabolites in Hypericum triquetrifolium Turra from Wild Populations of Turkey
(Sage Publications Inc, 2008)
The present study was conducted to determine the variation in the content of hyperforin, hypericin and pseudohypericin in Hypericum triquetrifolium Turra growing wild in four locations of Turkey. The aerial parts, representing ...
Variation of bioactive substances in Hypericum montbretii during plant growth
(Taylor & Francis Ltd, 2008)
The present study was conducted to determine phenologic and morphogenetic variation of chlorogenic acid and flavonoids, as rutin, hyperoside, apigenin-7-O-glucoside, quercitrin, quercetin and viteksin content of Hypericum ...
