background : with regard to an increase in the life expectancy for women and the consistency of the menopause age, a significant portion of women's age is passed after the menopause. menopause is considered as a critical and sensitive period due to the changes and the disorders that are involved in it. vasomotor symptoms, sleep disorders and psycho-mental changes are among the most prevalent sy...

Plant extract is a complex concoction of several phytochemicals, for instance, phenolics, sugars, flavonoids, xanthones, and others. In general, it said that hydroxyl-rich phenolics act as reducing agents metal ions, but little discussed about the stabilizing ligands nanoparticles (NPs). Thus, despite popularity plant extract-mediated synthesis NPs, phytochemical basis process exact mechanism a...

Objective: In this study, the effects of three different ozonated oils (Sesame, Nigella sativa, and Hypericum perforatum) on wound closure rate, healing process, possible complications were examined macroscopically microscopically. Materials Methods: Twenty-one adult Wistar albino female rats used in study. Subjects divided into groups, early healing, (7 days), medium (14 late (21 days). Four f...

Hypericum perforatum, known as St. John's Wort and most used ethnaformacolgically, belongs to the Hypericaceae family. In this work, we aimed evaluate antioxidant, antimicrobial, DNA protective activities, enzyme inhibitor properties of domestic import H. perforatum aqueous extracts. The total phenolic flavonoid contents were also determined for both samples. Results exhibited a high content Do...

BACKGROUND AND OBJECTIVE: Pulmonary fibrosis is a chronic interstitial lung disease caused by parenchymal lung damage due to inflammatory factors and fibrosis. Hypericum perforatum contains various flavonoids with antioxidant properties. This study aimed to evaluate protective effects of hydroalcoholic extract of Hypericum against bleomycin-induced pulmonary fibrosis in rats. METHODS: This empi...

The antioxidant potentials of a total ethanolic extract of Hypericum perforatum (TE) and fractions were evaluated and correlated with their phenolic contents. The extracts were fully characterised by HPLC–DAD–MS–MS. Kaempferol 3-rutinoside and rutinacetyl were identified for the first time in TE extracts. The free radical-scavenging properties of TE (EC50 1⁄4 21 lg dwb/ml) and fractions were st...
