“…The superoxide radical scavenging activity of the samples was assessed using the NADH-PMS-NBT (Nicotinamide Adenine Dinucleotide-Phenazine Methyl Sulfate-Nitrotetrazolium Blue Chloride) method described in the literature with some modifications [ 47 ]. Different concentrations of samples were prepared by dissolving samples in Tris-HCl buffer solution (pH 8.0, 0.05 mmol·L −1 ).…”

Paeonia ostii is a traditional medicinal plant popularly used in China. This study intended to evaluate the antioxidant properties and the chemical components of the flavonoid-rich extracts from the flowers of P. ostii. The results showed that the flavonoid-rich extracts from the flowers of P. ostii had strong scavenging capacities on 2,2′-Azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS), hydroxyls, superoxide anions, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals in a dose-dependent manner. Five flavonoids, dihydrokaempferol (1), apigenin-7-O-β-d-glucoside (2), apigenin-7-O-β-d-neohesperidoside (3), kaempferol-7-O-β-d-glucopyranoside (4), and kaempferol-3-O-β-d-glucopyranosyl-7-O-β-d-glucopyranoside (5), were isolated from the flavonoid-rich extracts of the flowers of P. ostii. High-performance liquid chromatography (HPLC) analysis revealed that compounds 3 and 4 were abundant in the P. ostii flower and in flavonoid-rich extracts. The main components of the flower of P. ostii are flavonoids. The high antioxidant activity of the flavonoid-rich extracts may be attributed to the high content of flavonoids. The five isolated flavonoids were the primary antioxidant ingredients, and may play important roles in the strong antioxidant activities of this flower. Based on the obtained results, the flower of P. ostii could be a potential source of natural antioxidants in food and pharmaceutical applications.

“…The EtOAc fraction showed the highest content of flavonoids, followed by the BuOH fraction, crude extract, PE fraction and aqueous fraction. Some studies have also indicated that considerable amounts of phenolics (especially flavonoids) are present in edible flowers, such as those of Musa basjoo (Tai, Chen, Qin, Cai, & Xu, 2014).…”

“…The literature reports that compound 1 (diglycosylated flavonoid) showed antiallergic actions (Ichikawa, Ogura, Lijima, 1986), high antioxidant potential (Nascimento et al, 2013) and antileishmanial activities (Muzitano et al, 2006a). Moreover, quercetrin (2) protected skin from UVB-induced inflammation (Yin et al, 2013), displayed antioxidant (Aderogba, Okoh, Idowu, 2005;Tai et al, 2014) and antileishmanial activities (Muzitano et al, 2006b), showed antiproliferative and apoptotic effects in colon cancer cells (Cincin et al, 2015), demonstrated gastroprotective actions (Mota et al, 2009) and showed intestinal anti-inflammatory effects (Camuesco et al, 2004). Júnior et al, (2014) reported that quercitrin was present in Croton campestris extracts at 2.34% and might be involved in gastroprotective activities against ethanol, acidified ethanol-, and indomethacin-induced gastric lesions.…”

Peptic ulcers are an important pathology, and the search for safer and more effective treatment methods is of paramount importance. In this study, we assess the gastroprotective effects of the hydroethanolic extract (HE) and ethyl acetate fraction (EAF) from Kalanchoe pinnata leaves against an ethanol/HCl-induced ulcer model in rats. The HE reduced gastric lesions by approximately 47% (400 mg/kg). A significant inhibition of the gastric lesions by 50% was observed after pretreatment with the EAF (200 mg/kg). Quercetrin and quercetin 3-O-α-L-arabinopyranosyl-(1→2)-α-L-rhamnopyranoside were isolated and identified in the flavonoid fraction (EAF) by HPLC and NMR analyses because this fraction showed the highest gastroprotective effect. This fraction demonstrated high antioxidant activities (CE 50 =41.91 µg/mL) by DPPH in comparison with Trolox ® and 11.33 mmol Trolox ® equivalent by ORAC. In conclusion, the HE and FAE from K. pinnata displayed gastroprotective activity in rats, most likely due to the presence of flavonoids.Uniterms: Gastric ulcer/study/rats. Gastric ulcer/treatment.

INTRODUCTIONFor the past two centuries, peptic ulcers have caused high morbidity and mortality (Malfertheiner, Chan, Mccoll, 2009). This disease is a serious and prevalent pathology (Calam, Baron, 2001). A peptic ulcer is a chronic lesion, usually single, that can be located in the gastric or duodenal mucosae (Kumar, Abbas, Fausto, 2005). In the UK, the incidence of this disease was 12% higher in men than in women (Araujo, Borini, Guimarães, 2014). A review article (January 1980 to February 2009 showed that the incidence rate of uncomplicated peptic ulcers was approximately one case per 1000 people per year in the general population; the incidence rate for complicated peptic ulcers that included bleeding and perforation was approximately 0.7 cases per 1000 people per year (Lin, Rodrígues, Hernándes-Diaz, 2011).The pathophysiology of peptic ulcers suggests that this disease is caused by an imbalance between defensive factors (mucus and bicarbonate secretion, mucosal barrier, blood flow, and prostaglandins) and destructive factors (reactive oxygen species and acid and pepsin secretion), resulting in the acute inflammation of the gastrointestinal mucosae (Laine, Takeuchi, Tarnawski, 2008). Several stimuli serve as offensive factors, including Helicobacter pylori, the use of nonsteroidal anti-inflammatory drugs (NSAIDs), stress, alcohol and cigarette smoking (Malfertheiner, Chan, Mccoll, 2009;Malnick et al., 2014). The current medical treatment for peptic ulcers is generally based on proton pump inhibitors and histamine H 2 -receptor blockers (Jain et al., 2007). However, the long-term use of these therapeutic agents can produce adverse effects, such as hypergastrinemia and hyperplasia in the enterochromaffinlike (ECL) cells, the risk of pneumonia, diarrhea and the disturbance of ...
