TL;DR: In this article, the presence of the phloroglucinol derivative hyperforin, the naphthodianthrones hypericin and pseudohypericin, phenylpropane chlorogenic acid and the flavonoids such as rutin, hyperoside, apigenin-7-Oglucoside and kaempferol were investigated in two Turkish species of Hypericum, namely, Hypericum scabrum L. and Hypericum bupleuroides Gris.
Abstract: 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, the naphthodianthrones hypericin and pseudohypericin, the phenylpropane chlorogenic acid and the flavonoids such as rutin, hyperoside, apigenin-7-O-glucoside, kaempferol, quercitrin, quercetin and amentoflavone were investigated in two Turkish species of Hypericum, namely, Hypericum scabrum L. and Hypericum bupleuroides Gris. The aerial parts representing a total of 30 individuals were collected at full flowering and dissected into floral, leaf and stem tissues. After being dried at room temperature, the plant materials were assayed for secondary metabolite concentrations by HPLC. All of the secondary metabolites examined were detected in both species at various levels depending on plant tissue except for hyperforin which was not accumulated in Hypericum scabrum. The presence of hyperforin and the phenolic compounds examined in both species were reported by us for the first time.

TL;DR: The investigation resulted in the characterization of 30 components representing 92% of the total volatiles, and sesquiterpenes such as β-sesquiphellandrene and beta;-caryophyllene were assigned as major compounds.
Abstract: Hypericum bupleuroides Griseb. (Guttiferae) was collected from the north eastern region of Turkey. The aerial parts were subjected to microdistillation for the isolation of volatiles that were subsequently analyzed by GC and GC/MS. The investigation resulted in the characterization of 30 components representing 92% of the total volatiles. Sesquiterpenes such as β-sesquiphellandrene (33.2%) and beta;-caryophyllene (20.2%) were assigned as major compounds.

TL;DR: According to the obtained of antioxidant datas, except for the result of total polyphenol assay, the dried leaves of Centuary ( Hypericum montbretii ) had the best antioxidant property that was realized in all results.
Abstract: Antioxidant activity 13 different samples of medicinal and aromatic plants of Centaury ( Hypericum montbretii) , Centaury ( Hypericum bupleuroides ), Blackthorn ( Paliurus spina-christi Mill), including leaf, flower and stem, was investigated using DPPH, FRAP and CUPRAC methods. Total flavonoid, total phenolic amount and the antibacterial features of extracts from these herbs were also determined. According to the obtained of antioxidant datas, except for the result of total polyphenol assay, the dried leaves of Centuary ( Hypericum montbretii ) had the best antioxidant property that was realized in all results. Accordingly test of total polyphenol, the content of yellow flower of Centuary (Hypericum montbretii) herb was measured as of 22.48±0.66 mg GAE /g dry herb sample and so this herb had the highest total phenolic content. Antimicrobial activity tests were carried out using disc diffusion methods with 12 microbial species and the most of them displayed good-moderate antimicrobial and antifungal activity .
