Biosynthesis of leukotriene (LT) by arachidonic acid involves 5-lipoxygenase (5-LO) as an important precursor. Here, we evaluated the role of pseudohypericin (PHP) for its postulated 5-LO inhibitory activity along with a Cys-LT receptor antagonist zafirlukast (ZFL) against inflammatory
Our previous studies found that 4 compounds, namely pseudohypericin, amentoflavone, quercetin, and chlorogenic acid, in Hypericum perforatum ethanol extract synergistically inhibited lipopolysaccharide (LPS)-induced macrophage production of prostaglandin E2 (PGE2). Microarray studies led us to
Hypericum perforatum (Hp) has been used medicinally to treat a variety of conditions including mild-to-moderate depression. Recently, several anti-inflammatory activities of Hp have been reported. An ethanol extract of Hp was fractionated with the guidance of an anti-inflammatory bioassay
Hypericum perforatum (St. John's wort) is an herb widely used as supplement for mild to moderate depression. Our prior studies established synergistic anti-inflammatory activity associated with 4 bioactive compounds in a fraction of a H. perforatum ethanol extract. Whether these 4 compounds also
Hypericum perforatum (Hp) is commonly known for its antiviral, antidepressant, and cytotoxic properties, but traditionally Hp was also used to treat inflammation. In this study, the anti-inflammatory activity and cytotoxicity of different Hp extractions and accessions and constituents present within
Hypericum perforatum (Hp) extracts contain many different classes of constituents including flavonoids and biflavonoids, phloroglucinols, naphthodianthrones, caffeic acid derivatives, and unknown and/or unidentified compounds. Many constituents may be responsible for the anti-inflammatory activity
The Iowa Center for Research on Botanical Dietary Supplements seeks to optimize Echinacea, Hypericum, and Prunella botanical supplements for human-health benefit, emphasizing antiviral, anti-inflammatory and anti-pain activities. This mini-review reports on ongoing studies on Hypericum. The Center
The present study shows for the first time the phenolic composition and the in vitro properties (antioxidant and inhibition of nitric oxide production) of Hypericum calabricum Sprengel collected in Italy. The content of hypericins (hypericin and pseudohypericin), hyperforin, flavonoids (rutin,
Plants of the genus Hypericum are widely used in folk medicine for the treatment of gastric ailments (including pectic ulcers), burns, swelling, inflammation, anxiety, as well as for bacterial and viral infections. The aerial parts of Hypericum rumeliacum Boiss. subsp. apollinis (Boiss. & Heldr.)
OBJECTIVE
To evaluate the methanolic extracts of aerial parts of Hypericum scabroides (HSM) (200 mg/kg, p.o.) for in vivo anti-inflammatory activity.
METHODS
The anti-inflammatory activity of HSM was tested in mice weighting (25±5) g. Either vehicle (control group), the methanolic extracts (200
In the present work we carried out a phytochemical and biological investigation on three endemic Hypericum species, i.e.Hypericum thymbrifolium (H. thymbrifolium), Hypericum spectabile (H. spectabile) and Hypericum pseudolaeve (H. pseudolaeve) from Anatolia in order to discover new sources of
The genus Hypericum includes more than 450 species distributed in Europe, North America, North Africa and West Asia. These plants are widely used in folk medicine for the treatment of inflammation, bacterial and viral infections, burns and gastric disorders. The use for alleviating inflammation and
Among 484 Hypericum L. (Guttiferae/Hypericaceae) species, widespread in warm temperate areas throughout the world, only H. perforatum is widely used in official medicine. Hypericum perforatum has been reported as an antidepressant, antiviral, antimicrobial, anti-inflammatory, and a healing agent.
