“…The antioxidant activity is related to the scavenging effect on radical DPPH and on the secretion of peroxidase in rat salivary glands (Alonso, Peralta, Lemos, Davicino, & Anesini, ; Anesini, Turner, Borda, Ferraro, & Coussio, ). It has also been demonstrated that the extract can prevent the oxidation of vitamin C in orange juice (Micucci, Alonso, Turner, Davicino, & Anesini,). To date, the preventive effect on food oxidative damage (inhibition of lipiperoxidation and AGEs formation in eggs during cooking) as well as the capacity of inhibition of protein hydrolysis by heat and by protease has not been determined with L. divaricata extracts.…”

The aim of this study was to evaluate the antioxidant and protease inhibitor capacities on eggs and milk protein of a nor‐dihydroguaiaretic (NDGA)‐standardized aqueous extract of Larrea divaricata (AE) and to analyze the participation of polyphenols as NDGA in these actions. NDGA was determined by high‐performance liquid chromatography; flavonoids and polyphenols were quantified by spectrophotometric methods as well as inhibition of lipid peroxidation, proteinase inhibitor capacity, advanced glycation end products (AGES) formation, and inhibition of albumin denaturation. The extract protected food for oxidative damage by preventing malondialdehyde formation in egg yolk and by preventing AGE formation in completely cooked eggs, also impeded albumin denaturation, and casein hydrolysis induced by trypsin and heat. Polyphenols, especially flavonoids and NDGA, were involved in these actions.

“…The experiment was carried out in triplicate. Briefly, 500 mg of the aqueous extract was compressed as a pill (the amount of the extract used was calculated in relation to the final concentration that exerts antioxidant activities in in vitro assays as additive (Micucci et al ., ; Turner et al ., )) and then incubated with the simulated gastric juice at 37°C for 1 h (step 1). In step 2, the material obtained after incubation with the simulated gastric juice (chyme) was incubated with the intestinal fluid at 37°C, for 2 and 4 h. These steps were carried out to mimic the digestion process discussed previously.…”

“…The antioxidant activity is reflected on the scavenging effect on the diphenylpicrylhydrazyl (DPPH) radical and on the secretion of peroxidase in rat salivary glands (Anesini et al ., ; Alonso et al ., ). It has also been demonstrated that the extract can prevent the oxidation of vitamin C in orange juice in a range of concentrations of 500–1000 μg/mL (Micucci et al ., ). To date, the relationship between the stability in a simulated digestion system and the antioxidant activity of L .…”

Larrea divaricata Cav. (Zygophyllaceae) is a South American plant widely distributed in Argentina that is used in folk medicine to treat inflammatory diseases. The aqueous extract is known to have well-documented biological activities such as antitumour, immunomodulatory, antimicrobial, antiinflammatory and antioxidant. However, its stability in gastrointestinal fluids is unknown. The latter is an important factor to assure the bioavailability of plant extracts intended to be administered via the oral route. The aim of this work was to study the stability of a lyophilized aqueous extract of L. divaricata compressed as a pill. To this end, the main polyphenol compound found in the extract, that is, the nordihydroguaiaretic acid, the total polyphenols and flavonoids content and the antioxidant activity such as diphenylpicrylhydrazyl scavenger activity and reducing power were assayed after subjecting the extract to different incubation times in simulated digestive fluids. The HPLC and spectroscopic methods were employed. Although the levels of polyphenols and flavonoids decreased upon incubation in gastric and intestinal fluids, the extract maintained its antioxidant activity related to the presence of nordihydroguaiaretic acid. These results are promising and encourage the potential use of the extract by the oral route as a supplement or phytomedicine with antioxidant activity. Copyright © 2017 John Wiley & Sons, Ltd.

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. Phytochemical analysis indicated the presence of tannins, saponins etc. Anthraquiones were completely absent in both the citrus peel and pulp.
