Effects of Litchi chinensis fruit isolates on prostaglandin E2 and nitric oxide production in J774 murine macrophage cells

Inhibition of methanol extract from the aerial parts of Saururus chinensis on lipopolysaccharide-induced nitric oxide and prostagladin E2 production from murine macrophage RAW 264.7 cells.

As an attempt to search for bioactive natural products exerting antiinflammatory activity, we have evaluated the effects of the methanol extract from the aerial parts of Saururus chinensis (LOUR.) BAILL (Saururaceae) on lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E(2) (PGE(2)) release by the macrophage cell line RAW 264.7. Our data indicate that this extract is a potent...

Antioxidant potential and hepatoprotectivity of hydromethanolic extract of Litchi chinensis fruits: In vivo and in vitro studies

The antioxidant activity and phytoconstituents of the hydromethanolic extract of Litchi chinensis (HELC) fruit was explored in the present study. The antioxidant potential of extract has been evaluated using several antioxidant models and results were compared to standards. Fruit extract showed effective reducing power and free radical scavenging activity in a dose-dependent manner. In case o...

Inhibitory Effects of β-Chamigrenal, Isolated from the Fruits of Schisandra chinensis, on Lipopolysaccharide-Induced Nitric Oxide and Prostaglandin E2 Production in RAW 264.7 Macrophages.

Anti-inflammatory effects of schisandrin isolated from the fruit of Schisandra chinensis Baill.

Schisandrin is the main active ingredient isolated from the fruit of Schisandra chinensis Baill. Recent studies have demonstrated that schisandrin exhibits anti-oxidative effects in vivo. In the present study, the effect of schisandrin on plasma nitrite concentration in lipopolysaccharide (LPS)-treated mice was evaluated. It also significantly inhibited carrageenan-induced paw edema and acetic ...

اثر اسانس آویشن شیرازی بر تولید یون سوپراکسید و نیتریک اکسید و بیان ژن‌های NADH اکسیداز و نیتریک اکسید سنتاز در سلول‌های ماکروفاژ

Objective: In this study, inhibitory effect of Zataria multiflora essential oil on superoxide and nitric oxide production and NADH oxidase (NOX) and nitric oxide synthase (NOS) expression was examined. Materials and Methods: Zataria essential oil was obtained by hydro-distillation and chemical composition was analyzed by gas chromatography-mass spectrometry (GC-MS). Superoxide and ni...
