Metabolomics reveals impact of seven functional foods on metabolic pathways in a gut microbiota model.
Abstract
Functional food defined as dietary supplements that in addition to their nutritional values, can beneficially modulate body functions becomes more and more popular but the reaction of the intestinal microbiota to it is largely unknown. In order to analyse the impact of functional food on the microbiota itself it is necessary to focus on the physiology of the microbiota, which can be assessed in a whole by untargeted metabolomics. Obtaining a detailed description of the gut microbiota reaction to food ingredients can be a key to understand how these organisms regulate and bioprocess many of these f...

Effects of prickly pear (Opuntia ficus-indica L.) peel flour as an innovative ingredient in biscuits formulation
This study was aimed at assessing the aptitude of prickly pear peel flour to be mixed (10 g, 20 g, and 30 g/100 g) with wheat flour for biscuits preparation through the analysis of the physical and chemical properties of doughs and biscuits and through sensory evaluation.The composition of prickly pear flour showed a significantly higher concentration of fibre (20.70 g/100 g d.w.), ash (14.57 g/100 g d.w.), and phenolic compounds (277.6 mg/100 g d.w.) compared to the control wheat flour, thus improving technological properties such as the aptitude to kneading, the flavour retention, and the antioxid...

Molecules, Vol. 25, Pages 916: Opuntia Fruits as Food Enriching Ingredient, the First Step towards New Functional Food Products
t-Miotła
Prickly pear (Opuntia ficus indica (L.) Mill.) is a rich source of vitamins C, B1, B2, A, and E, minerals such as calcium, potassium, magnesium, iron, and phosphorus, as well as bioactive substances, i.e., carotenoids, betalains, and phenolic compounds. Of these, the phenolic acids, betalains, and flavonoids are notable in that they are largely responsible for the health-promoting properties of this plant. The purpose of the presented research was to first determine the antioxidant properties and the content of polyphenolic compounds (including individual phenolic acids) in prickly pear fruit, then to produce...

Identification and genomic characterization of a novel tobamovirus from prickly pear cactus
AbstractIn this work, we describe the complete sequence and genome organization of a novel tobamovirus detected in a prickly pear plant (Opuntia sp.) by high-throughput sequencing, tentatively named “opuntia virus 2”. The full genome of opuntia virus 2 is 6,453 nucleotides in length and contains four open reading frames (ORFs) coding for the two subunits of the RNA polymerase, the movement protein, and the coat protein, respectively. Phylogenetic analysis using the complete nucleotide seque nce revealed that the virus belongs to the genusTobamovirus (familyVirgaviridae), showing the highest nucleotide sequence identity...

Investigation of Amounts of Vitamins, Lycopene, and Elements in the Fruits of Opuntia ficus-indica Subjected to Different Pretreatments.
In this study, Opuntia ficus-indica fruit was examined in fresh, frozen, sun-dried, and microwave-dried. Analysis of the vitamins in the samples was performed by high performance liquid chromatography (HPLC). The amount of selenium in the fruits was determined by fluorescence spectrophotometer, while copper, iron, manganese, and zinc were determined by atomic absorption spectrophotometer (AAS). Amount of vitamins in the fruit of Opuntia ficus-indica were decreased (p < 0.005) in sun- and microwave-dried samples in comparison with fresh sample. Decrease of vitamins in frozen fruits was statistically insignificant com...

Determination of Antioxidant and Antifungal Activities in Cookies Fortified with Solar Dried Prickly Pear Peels Powder.
CONCLUSION: Addition of 5% dried cactus peel had lower overall quality and color than the control. Adding 3% of PPPP to cookies (qaraqeesh) showed the highest sensory score. Dried cactus peels may improve quality, nutritional value and shelf life of cookies.

Cholesterol transporter proteins in HepG2 cells can be modulated by phenolic compounds present in Opuntia ficus-indica aqueous solutions
This study tested the hypothesis that phenolic compounds can modulate the level of cholesterol transporters including Niemann-Pick C1-like 1 (NPC1L1) and ATP-binding cassette transporters in liver cells. HepG2 cells, used as a model of hepatocytes, showed a decrease in the abundance of cholesterol transporters comparatively to the control when treated with the Opuntia ficus-indica’s cladodes decoction. The decrease was between 13–70%, 25–60%, 9–60% and 23–60% for NPC1L1, ABCA1, ABCG5 and ABCG8 transporters, respectively, when using between 0.15 and 0.35 mg/mL of decoction in the culture medium. FTIR analysis sh...

Isolation and characterization of opuntiol from Opuntia Ficus indica (L. Mill) and its antiproliferative effect in KB oral carcinoma cells.
In this study, we isolated and characterized a novel bioactive flavonol from the cactus pad of Opuntia Ficus indica Indica (L. Mill) (OFI) by chromatography techniques. The isolated compound was characterized by FT-IR, 1H and 13C NMR spectroscopy. Single-crystal XRD results illustrate that the obtained flavonol was opuntiol (6-hydroxymethyl-4-methoxy-2H-pyran-2-one) and it was found to be near planar except for the H atoms of the methylene and methyl groups. The crystal packing was stabilized by C-H….O and O-H….O intermolecular hydrogen bonds. The isolated opuntiol significantly inhibited KB cells proliferation and its...
