A variety of in vitro models such as β-carotene−linoleic acid, 1,1-diphenyl-2-picryl hydrazyl (DPPH), superoxide, and hamster low-density lipoprotein (LDL) were used to measure the antioxidant activity 11 citrus bioactive compounds. The compounds tested included two limonoids, limonin (Lim) 17-β-d-glucopyranoside (LG); eight flavonoids, apigenin (Api), scutellarein (Scu), kaempferol (Kae), rutin trihydrate (Rut), neohesperidin (Neh), neoeriocitrin (Nee), naringenin (Ngn), naringin(Ng); a...
Aim: This study investigated the quorum sensing, biofilm and type three secretion system (TTSS) inhibitory properties of citrus flavonoids. Methods Results: Flavonoids were tested for their ability to inhibit sensing using Vibrio harveyi reporter assay. Biofilm assays carried out in 96-well plates. Inhibition formation Escherichia coli O157:H7 V. by flavonoids was measured. Furthermore, effect naringenin on expression TTSS semi-quantitative PCR. Differential responses different observed...
Mom's conventional wisdom of eating fruits and vegetables to lead a healthy life has evolved with scientific, fact-finding research during the past four decades due advances in science "Foods for Health". Epidemiological prospective studies have demonstrated vital role fruits, vegetables, nuts reducing risk cancer cardiovascular diseases. In recent years, several meta-analyses strongly suggested that by adding one serving daily diet, diseases will be decreased up 7%. The multidisciplinary...
Abstract Seed priming uses treatments to improve seed germination and thus potentially increase growth yield. Low-cost, environmentally friendly, effective treatment remain be optimized tested for high-value specialty crop like watermelon ( Citrullus lanatus ) in multi-locations. This remains a particularly acute problem triploids, which produce desirable seedless watermelons, but show low rates. In the present study, turmeric oil nanoemulsions (TNE) silver nanoparticles (AgNPs) synthesized...
The lower incidences of many chronic diseases such as cancer and cardiovascular related ailments are associated with consumption vegetables rich dietary regimes this has been substantiated through numerous in vitro, pre-clinical clinical investigations. Members cruciferous family cultivated widely consumed universally a part daily diet. major includes broccoli, cauliflower, radish, kale, brussels sprouts, watercress cabbage that used either fresh (salads), steamed or cooked. Besides...
In the present study, onion extract was used for green synthesis of iron oxide nanoparticles (Fe-NPs). The X-ray diffraction, photoelectron spectroscopy, and high-resolution transmission electron microscopy characterizations demonstrated that biosynthesized Fe-NPs were mainly composed low-crystalline or amorphous Fe2O3 with diameter 19–30 nm. effect seed priming different concentrations (20, 40, 80, 160 mg L–1) on seedling growth parameters, photosynthetic pigments, antioxidant potential,...
This study evaluated the hypothesis that untreated and irradiated grapefruit as well isolated citrus compounds naringin limonin would protect against azoxymethane (AOM)-induced aberrant crypt foci (ACF) by suppressing proliferation elevating apoptosis through anti-inflammatory activities. Male Sprague–Dawley rats ( n = 100) were provided one of five diets: control (without added components), or (300 Gy, 137 Cs) pulp powder (13.7 g/kg), (200 mg/kg) mg/kg). Rats injected with saline AOM (15...
Lime (Citrus aurantifolia Swingle) is one of the major citrus fruits and widely consumed, but there limited evidence about its health-promoting properties. Hence, an investigation was conducted to understand chemopreventive effects lime juice on pancreatic cancer cells possible mechanism for induction apoptosis using Panc-28 cells. Freeze-dried extracted with different solvents, such as chloroform, acetone, MeOH, MeOH/water (8:2). The chloroform extract showed highest (85.4 90%)...
Green nanotechnology is rapidly expanding in sustainable precision agriculture that promises to revolutionize food production. In the present study, nanoparticles (NPs) were synthesized using a green process involving use of onion extracts as reducing agents. Silver (AgNPs) and gold (AuNPs) extract characterized by UV–vis spectrophotometry, dynamic light scattering technique, X-ray diffraction, transmission electron microscopy, liquid chromatography–mass spectrometry. addition, two...
Epidemiological evidence suggests that a diet abundant in fruits and vegetables may protect against colon cancer. Bioactive compounds, including flavonoids limonoids, have been shown to possess antiproliferative antitumorigenic effects various cancer models. This experiment investigated the of four citrus one limonoid mixture at promotion stage chemically induced rats. Male Sprague–Dawley rats ( n = 10 rats/group) were randomly allocated six diets formulated contain 0.1% apigenin, 0.02%...
The composition of betalain, red or yellow pigments, and betaine (trimethylglycine glycinebetaine) nine beetroot ( Beta vulgaris L.) cultivars produced in the greenhouse field was studied. Inhibition HepG2 cell proliferation by betanin also tested. Four predominant betalains, two betacyanins (betanin isobetanin) betaxanthins (vulgaxanthin I miraxanthin V), were isolated quantified. Betanin vulgaxanthin major compounds extracts, respectively, they comprised >90% betalain content tested...
Dietary flavonoids are used in treatment of multiple diseases, and their antiinflammatory effects the intestine due, part, to interactions with gut microflora possibly due modulation aryl hydrocarbon receptor (AhR) signaling. In this study, we investigated structure-dependent AhR activity 14 Caco2 colon cancer cells using induction CYP1A1 UGT1A1 gene expression as endpoints. A major structural determinant for activation was number hydroxyl groups where pentahydroxyflavonoids (with exception...
Limonoids have been shown to inhibit the growth of estrogen receptor-negative and -positive human breast cancer cells in culture. The primary objective this study was test antiproliferative activity limonoids (obacunone 17 beta-D-glucopyranoside, nomilinic acid limonin, nomilin, a limonoid glucoside mixture), found high concentrations mandarin (Citrus reticulata Blanco), against series cell lines. lines included leukemia (HL-60), ovary (SKOV-3), cervix (HeLa), stomach (NCI-SNU-1), liver (Hep...
The aglycone, or free quercetin, and total quercetin content of 75 cultivars selections was analyzed by reverse-phase high-performance liquid chromatography. Quercetin glycosides were hydrolyzed into aglycones. Total in yellow, pink, red onions varied from 54 to 286 mg·kg -1 fresh weight different onion entries grown during 1992. White contained trace amounts quercetin. Free all the low (< 0.4 ) except `20272-G' (12.5 weight). Bulbs stored at 5, 24, 30C controlled atmosphere (CA) for...
