“…A synergistic reducing power could be also played by polysaccharide content detected in RTE. It has been reported that polysaccharides could have a reducing and antiulcerogenic activities (Galati et al 2001;Zhong et al 2010). The reducing ability attributed to phenolics, flavonoids and polysaccharide could confer to the RTE an in vivo antiulcerogenic effect.…”

“…The chemical study of RTE also revealed the presence of polysaccharide content but appeared lower than that the level detected in swallow root known for their antiulcerogenic effect (Srikanta et al 2007). It has been demonstrated that phenolic, flavonoids, condensed tannins and polysaccharide possess an ideal structural chemistry for free radical scavenging activity which arise 1) from their high reactivity as hydrogen or electron donors, 2) from their ability to stabilize and delocalize the unpaired electron (chain-breaking function), and 3) from their potential to chelate metal ions (termination of the Fenton reaction) (Galati and O'Brien 2004;Chanda and Dave 2009;Zhong et al 2010).…”

Abstract. Rhus tripartitum (sumac) is an Anacardiaceae tree with a wide phytotherapeutic application including the use of its roots in the management of gastric ulcer. In the present study the Rhus tripartitum root barks extract (RTE) was phytochemical studied, in vitro tested for their potential antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and reducing power assay and in vivo evaluated for its ability to prevent ethanol-induced gastric ulcer in rats. The RTE was rich in phenolics, flavonoids, tannins and polysaccharide contents and exhibited a low but not weak in vitro antioxidant activity when compared with (+)-catechin. Pre-treatment with RTE at oral doses 50, 200 and 400 mg/kg body weight was found to provide a dose-dependent protection against ethanolinduced ulcer by averting the deep ulcer lesions of the gastric epithelium, by reducing gastric juice and acid output, by enhancing gastric mucus production by preserving normal antioxidant enzymes activities, and inhibiting the lipid peroxidation. The antiulcerogenic activity of RTE might be due to a possible synergistic antioxidant and antisecretory effects.

Seasonal variability of phenolic compounds and antioxidant activity in prickly pear cladodes of Opuntia and Nopalea genres

et al. 2017

The prickly pear is a cactaceae that have chemical compounds that act as natural antioxidants. In addition, the prickly pear is a plant widely used in semiarid region as it's considered very important forage for animal feed, especially in the dry season. The objectives of this research were to characterize the main classes of phytochemicals, determine the phenols content, flavonoids and anthocyanins and evaluate the antioxidant activity of the prickly pear cultivars Opuntia and Nopalea grown in the semiarid region of Pernambuco in two collection periods (dry and rainy). In the work crude ethanol extracts from cladodes of cultivars (IPA-20, Elephant Ear Mexican, F-08, V-19, Small palm, F-21 and IPA-Sertânia) were used. As for the class of phytochemical compounds from ethanol extract only the flavonoids and steroids were detected in all prickly pear cultivars, in both periods analyzed. The content of phenolic compounds ranges from 1.24 to 5.41 mg GAE g -1 DM, flavonoids 0.90 to 3.43 mg QE g -1 DM, anthocyanins from 0.05 to 0.34 µg QE 100 g -1 DM and antioxidant activity 39.59 to 217.17 µM TEAC g -1 DM. The occurrence of chemical variability and antioxidant activity were observed, both among the botanical cultivars studied and among the collection periods.Keywords: biodiversity and nutrition; cactus pear; flavonoids; phenolic acids; phytochemicals.Practical Application: Use of cladodes of prickly pear cultivars as functional foods in the diet human and animal.

The aim of this work was the obtainment of Opuntia fícus-indica (L.) Mill extract for the development of cosmetic formulations and in vivo evaluation of its moisturizing effects. The formulations were tested for preliminary and accelerated stability. Organoleptic characteristics, pH values and rheological behavior were assessed. The evaluation of moisturizing efficacy of the emulsions formulated with 3.0% of Polyacrylamide (and) C13-14 Isoparaffin (and) Laureth-7 containing 1.0 and 3.0% of O. ficus-indica hydroglycolic extract (EHG001) was performed using the capacitance method (Corneometer®) and the transepidermal water loss -TEWL evaluation (Tewameter®). The emulsions formulated were stable, exhibiting pseudoplastic and thixotropic behavior. The results of evaluation of moisturizing efficacy showed increased skin hydration after five hours by mainly increasing the skin barrier effect. The formulations containing 1.0 and 3.0% of EHG001 enhanced the skin barrier effect by reducing TEWL up to four hours after application. The results observed suggest that O. ficus-indica hydroglycolic extract may act through a humectant and occlusion mechanism.Uniterms Opuntia fícus indica/emulsion stability.
