Besides the chemotaxonomic value, nowadays determination of biodiversity and chemical variability has a commercial impact. The exact identity raw material constituents botanical products, such as food supplements or herbal remedies, is very important argument, being real prerequisite for quality control traceability, followed by active components. However, analytical approach must consider natural great in secondary metabolites product form, extracts. Against reductive approach, on basis...
A hydroalcoholic extract from female inflorescences of Humulus lupulus L. (HOP extract) was evaluated for its anti-influenza activity. The ability the to interfere with different phases viral replication assessed, as well effect on intracellular redox state, being unbalanced versus oxidative state in infected cells. radical scavenging power, inhibition lipoperoxidation, and ferric reducing activity were assayed antioxidant mechanisms. phytochemical characterization also performed. We found...
DR2B and DR2C extracts, obtained by ethanolic maceration of peel from commercially physiologically ripe aubergine berries, were studied for the antioxidative cytoprotective properties anti-HSV-1 activity, in line with evidence that several antioxidants can impair viral replication maintaining reducing conditions host cells. The effects against tBOOH-induced damage assessed Caco2 cells, while antiviral activity was Vero cells; polyphenolic fingerprints characterized integrated phytochemical...
The purity of solvents used in medical, herbal and food products is an essential prerequisite. This communication focused on the possible occurrence phthalates contaminant derived from utilisation plastic containers for instead glass containers. contamination must be detected also marketed extracts, like botanical supplements.
Context: Hypericin, isolated from Hypericum perforatum L. and about another 300 species (Guttiferae), is one of the most powerful photosensitizers found in nature.Objective: The aim this study was to assess variability chemical composition biological activities four H. samples, collected at different altitudes South Apennine Italy.Materials methods: MTT assay used evaluate antiproliferative activity samples concentrations (0.6–100 µg/mL) after irradiation 365 nm. inhibition nitric oxide...
Pomegranate peel is a natural source of phenolics, claimed to possess healing properties, among which are antioxidant and antidiabetic. In the present study, an ethyl acetate extract, obtained by Soxhlet from Dente di Cavallo DC2 pomegranate (PGE) characterized contain 4% w/w ellagic acid, has been evaluated for its hypoglycemic, antiglycation, antioxidative cytoprotective in order provide possible evidence future nutraceutical applications. The α-amylase α-glucosidase enzyme inhibition,...
Analysis of the complex composition cocoa beans provides fundamental information for evaluating quality and nutritional aspects cocoa-based food products, nutraceuticals supplements. Cameroon, world's fourth largest producer cocoa, has been defined as "Africa in miniature" because variety it habitats. In order to evaluate characteristics from five different regions we studied their polyphenolic content, volatile compounds fatty acids composition. The High Performance Thin Layer...
Abstract Objectives Our interest continues in discovering phytocomplexes from medicinal plants with phototoxic activity against human melanoma cells; thus the aim of present study was to assess antioxidant, anti‐inflammatory and Hypericum perforatum L. subsp. , relate these properties plant's chemical composition. Materials methods Components H. were extracted by hydroalcoholic solution profiles preparations (Hy TE ‐3) performed HPTLC . Linoleic acid peroxidation DPPH tests used antioxidant...
The in vitro antifungal activity of extracts obtained from 14 medicinal plants the mongolian flora were investigated by measuring their minimal inhibitory concentration (MIC) against fungi cause cutaneous diseases such as Candida species, dermatophytes and Malassezia furfur. Among species examined, Stellaria dichotoma L., Scutellaria scordifolia L. Aquilegia sibirica Fisch. Et Schrenk. Hyoscyamus niger demonstrated all studied fungi. In particular, S. methanol extract, at room temperature,...
The chemical composition of three rockrose Cistus species, monspeliensis, libanotis and villosus, collected in Tunisia, was studied by HPTLC, focusing on the terpenes phenols constituents. Diterpenes are important as main constituents leaf sticky aromatic resin, known labdanum, which highly appreciated perfumery. Polyphenols methanolic extracts each species were identified, quantified total flavonoids tannins, tested for antioxidant activity. evident C. whereas they practically absent...
In recent years food supplement market increased constantly, including slimming products and against obesity. The case of rasberry ketone (RK) is here reported. HPTLC HPLC-DAD analyses on a marketed product containing raspberry juice evidenced an abnormal quantity RK, not in accordance with the natural content. reported data confirm need adequate controls supplements necessity complete adherence between labelling real constitution product. Practical Applications Determining origin assuring...
DR2B and DR2C extracts, from peel of commercially physiologically ripe eggplants, were studied for the antioxidative cytoprotective properties anti-HSV-1 activity, in line with evidence that several antioxidants can impair viral replication by maintaining reducing conditions into host cells. The effects against tBOOH-induced damage was assessed Caco2 cells, while antiviral activity Vero cells; phenolic anthocyanin fingerprint characterized integrated phytochemical methods. Results...
