Abstract
The addition of chia seeds and goji puree (2.5 and/or 5%) was evaluated in terms of their effects on the fatty acid profile, lipid peroxidation, total phenols and antioxidant capacity of cooked beef burgers. In comparison to control burgers, polyunsaturated fatty acids doubled or tripled in samples containing chia seeds; polyphenols and antioxidant capacities (ORAC, ABTS, DPPH) increased up to 70% and malondialdehyde values were reduced up to 50% in burgers formulated with both ingredients. Polyphenols, antioxidant capacity and lipid peroxidation were also assessed after in vitro digestion. A marked increase of polyphenol bioaccessibility and antioxidant capacity was observed for all samples, but also malondialdehyde values were increased after digestion, especially in samples containing 5% chia seeds. Finally, hedonistic tests were conducted on young (18-30 years), adult (31-60 years) and elderly (>60 years) subjects and the burgers resulted acceptable by all groups, appointing to their potential application as functional burgers.

Abstract
Moringin (MOR), a glycosyl-isothiocyanate obtained by myrosinase-catalyzed hydrolysis of the precursor 4-(α-l-rhamnosyloxy)-benzyl glucosinolate (glucomoringin), found predominantly in the seeds of Moringa oleifera, shows anticancer effects against several cancer cell lines. Avenanthramide (AVN) 2f is a phytochemical purified from oats with antioxidant and anticancer properties. The aim of this study was to investigate the antiproliferative and proapoptotic effects of MOR and AVN 2f used alone and in combination on Hep3B cancer cells, which are highly resistant to conventional anticancer drugs. We found that a cocktail of MOR and AVN 2f significantly inhibited the Hep3B proliferation rate by markedly increasing the activity of caspases 2, 8, 9, and 3. Extrinsic apoptosis was induced by the AVN 2f-mediated activation of caspase 8, while the intrinsic apoptotic pathway was triggered by MOR-induced increase in the levels of intracellular reactive oxygen species, MOR-mediated activation of caspases 2 and 9 and the MOR-mediated downregulation of the prosurvival gene BIRC5. Our results suggest that the combination MOR + AVN 2f could be an effective chemopreventive cocktail against the development of hepatocarcinoma.

Abstract
BACKGROUND The demand for zero and reduced-sugar food products containing cocoa is expanding continuously. The present study was designed to evaluate the feasibility of producing high-quality chocolate sweetened with a crude extract of Stevia rebaudiana (Bertoni) prepared by a green microwave-assisted water-steam extraction procedure. Seven approximately isosweet chocolate formulations were developed, mixing cocoa paste, sucrose, commercial stevioside, crude green extract and maltitol in different proportions. All samples were analyzed for the determination of polyphenol and flavonoid content, antioxidant activity, and sensory acceptability. RESULTS The use of a crude stevia extract allowed low-sugar, high-quality chocolates to be obtained that were also acceptable by consumers and had a significant increased antioxidant activity. Moreover, consumers' segmentation revealed a cluster of consumers showing the same overall liking for the sample with 50% sucrose replaced by the stevia crude extract as that obtained with the commercial stevioside and the control sample (without sucrose replacement). CONCLUSION The results provide information that can contribute to promoting the development of sweet food products, with advantages in terms of an improved nutritional value (reduced sugar content and increased antioxidant activity) and a reduced impact of the production process on the environment. © 2016 Society of Chemical Industry.

Abstract
BACKGROUND Glucobrassicin (GBS), a glucosinolate contained in many brassica vegetables, is the precursor of chemopreventive compounds such as indole-3-carbinol. Large amounts of GBS would be needed to perform studies aimed at elucidating its role in the diet. This study was mainly undertaken to evaluate the flower buds of Isatis canescens as a source for GBS purification. In order to investigate the health-promoting potential of this species, glucosinolate, phenol and flavonoid content as well as the whole antioxidant capacity were also determined. Flower bud samples were collected in four localities around Mount Etna in Sicily, Italy, where I. canescens is widespread, as they are locally traditionally eaten. RESULTS I. canescens flower buds displayed high GBS concentrations, up to 60 µmol g(-1) dry weight. The purification method consisted of two chromatographic steps, which made it possible to obtain GBS with a purity of 92-95%, with a yield of 21 g kg(-1) . The total glucosinolates, phenols, flavonoids and antioxidant activity were considerable, with the southern locality showing the highest concentrations for all the phytochemicals. CONCLUSION I. canescens flower buds represent a naturally rich source of GBS, at a level suitable for its purification. Furthermore, flower bud consumption could provide an intake of health-promoting compounds, with possible antioxidant and chemopreventive properties.

Abstract
Fruit beverages are source of antioxidants, but their sugar content plays an important role in the epidemic of obesity. In this study, we considered 32 fruit beverages consumed in Italy (13 fruit juices, 11 nectars, and 8 fruit drinks), which were analyzed for caloric intake, total phenols (TP), ascorbic acid, and antioxidant capacity (oxygen radical absorbance capacity (ORAC) method). Results showed that the caloric intake was almost completely provided by the sugar content, ranging from 5.5 to 19%. The ORAC/kcal ratio was taken as an indicator of the antioxidant performance of fruit beverages. Fruit juices containing berries, red orange, and goji showed the best performances, together with berries or pears nectars and fruit drinks made with rose hips or tea extracts. The 95% of antioxidant capacity was provided by TP, which showed a significant linear correlation with the net ORAC values. Overall, the results indicate that the ORAC/kcal ratio is a suitable parameter to rank the quality of fruit beverages.

Abstract
Bromelain (Br) is a cysteine peptidase (GenBank AEH26024.1) from pineapple, with over 40 years of clinical use. The constituents mediating its anti-inflammatory activity are not thoroughly characterized and no peptide biomarker exists. Our objective is to characterize Br raw material and identify peptides in the plasma of Br treated mice. After SDS-PAGE in-gel digestion, Br (VN#3507; Middletown, CT, USA) peptides were analyzed via LC/MS/MS using 95% protein probability, 95% peptide probability, and a minimum peptide number = 5. Br spiked mouse plasma (1 ug/ul) and plasma from i.p. treated mice (12 mg/kg) were assessed using SRM. In Br raw material, we identified seven proteins: four proteases, one jacalin-like lectin, and two protease inhibitors. In Br spiked mouse plasma, six proteins (ananain, bromelain inhibitor, cysteine proteinase AN11, FB1035 precursor, FBSB precursor, and jacalin-like lectin) were identified. Using LC/MS/MS, we identified the unique peptide, DYGAVNEVK, derived from FB1035, in the plasma of i.p. Br treated mice. The spectral count of this peptide peaked at 6 hrs and was undetectable by 24 hrs. In this study, a novel Br peptide was identified in the plasma of treated mice for the first time. This Br peptide could serve as a biomarker to standardize the therapeutic dose and maximize clinical utility.

Abstract
INTRODUCTION Beta vulgaris var. cicla (BV) leaves contain chemopreventive compounds that have been investigated for new drug discovery. These compounds belong to the family of the apigenin-glycosides. Since the leaves are seasonal products containing high percentages of water, they are easily degradable during storage in fresh conditions. To be stored they require a drying process, consuming time and a large amount of energy. The extraction of apigenin-glycosides may also be conveniently performed from BV seeds, which represent a stable and year-long available biomass. OBJECTIVES The present report was undertaken to find a strategy of purification of bioactive flavonoids from BV seeds and test their ability to inhibit proliferation both on human colon cancer (RKO) cells and normal human fibroblasts (HF). MATERIALS AND METHODS The ethyl-acetate extract of BV seeds was fractionated on a Sephadex LH 20 column. A fraction of this extract, labeled as P4, exploited a marked antiproliferative activity on RKO cells. The components of P4 were purified on an RP₁₈ column chromatography and identified by HPLC-ESI-MS as 2,4,5-trihydroxybenzaldehyde, 2,5-dihydroxybenzaldehyde, vanillic acid, xylosylvitexin, glucopyranosyl-glucopyrasyl-rhamnetin and glucopyranosyl-xylosyl-rhamnetin. All of them were tested for cytostatic and cytotoxic activity on RKO and HF cells. RESULTS Xylosylvitexin exhibited the strongest antiproliferative activity on RKO cells, together with an enhancement of the apoptosis, an increase of cells in the G₁ phase and a reduction of cells in the S phase; on the contrary, the proliferation of HF was significantly stimulated. CONCLUSION Xylosylvitexin is the main and more efficient chemopreventive compound in BV seeds, but the natural cocktail of molecules, represented by P4 fraction, showed a better compromise between the antiproliferative activity on RKO cells and the enhancement of HF proliferation.

Abstract
The isolation and identification of a phytocomplex from olive mill waste waters (OMWW) was achieved. The isolated phytocomplex is made up of the following three phenolic compounds: hydroxytyrosol (3,4-DHPEA), tyrosol (p-HPEA) and the dialdehydic form of decarboxymethyl elenolic acid, linked with (3,4-dihydroxyphenyl)ethanol (3,4-DHPEA-EDA). The purification of this phytocomplex was reached by partial dehydration of the OMWW, followed by liquid-liquid extraction with ethyl acetate and middle pressure liquid chromatography (MPLC) on a Sephadex LH-20 column. The phytocomplex accounted for 6% of the total phenolic content of the OMWW. The phytocomplex and individual compounds were tested for antioxidant capacity by the oxygen radical absorbance capacity (ORAC) method. The ORAC phytocomplex produced 10,000 ORAC units/g dry weight, whereas the cellular antioxidant activity, measured by the cellular antioxidant activity in red blood cell (CAA-RBC) method, demonstrated that the phytocomplex and all of the components are able to permeate the cell membrane thus exhibiting antioxidant activity inside the red blood cells. Our phytocomplex could be employed in the formulation of fortified foods and nutraceuticals, with the goal to obtain substantial health protective effects due to the suitable combination of the component molecules.
