The dietary supplements with claimed antioxidant activity constitute a substantial part of the dietary supplement market. In this study, we performed the LC-QTOF-MS analysis and investigated the activity profiles of popular antioxidant dietary supplements from different chemical groups in terms of quality control. The commonly used antioxidant tests and statistical analysis revealed that substantial part of the results was comparable if 1 g sample was considered, but while comparing single and daily doses, significant differences in antioxidant values were noticed in all assays. The best antioxidant activity was obtained in ORAC assay (from 142 to 13814 μM of Trolox equivalents per 1 g of sample), and the strongest correlation occurred between TPC and ORAC. The LC-QTOF-MS analysis revealed that catechins were present in samples having the best antioxidant activity and that dietary supplements showing the weakest activity contained very small amount of any chemical constituents.

Macrolepiota Procera

The present study aimed to investigate the chemical composition, bioactive compounds, and antioxidant activity of two wild edible mushrooms, the honey fungus (Armillaria mellea) and the parasol mushroom (Macrolepiota procera), collected from Northern Morocco (MA) and Portugal (PT). Those species were chosen due to their edibility, nutraceutical, and medicinal properties. Bioactive compounds (ascorbic acid, tannin, total phenolic, total flavonoid, β-carotene, and lycopene) and their antioxidant activity were determined by spectrophotometric methods. Herein, the fruiting body of the samples revealed a significantly higher amount of bioactive compounds, and values varied between the Moroccan and the Portuguese ones. Methanolic extracts shown a strong antioxidant capacity: Using DPPH free radical-scavenging activity radicals (IC50 1.06–1.32 mg/mL); inhibition of β-carotene bleaching radicals (IC50 0.09–0.53 mg/mL); and, reducing power radicals (IC50 0.52–1.11 mg/mL). The mushroom species with the highest antioxidant capacity was A. mellea from MA. Chemical composition was analyzed by GC-MS and LC-MS methodologies. GC-MS analysis showed that the most abundant biomolecules group was sugar compositions in the four samples (62.90%, 48.93%, 59.00%, and 53.71%) and the main components were galactitol 16.74%, petroselinic acid 19.83%, d-galactose 38.43%, and glycerol 24.43% in A. mellea (MA), A. mellea (PT), M. procera (MA), and M. procera (PT), respectively. LC-MS analysis of individual phenolic compounds revealed that vanillic acid (198.40±2.82 µg/g dry weight (dw) and cinnamic acid (155.20 ± 0.97 µg/g dw) were the main compounds detected in A. mellea, while protocatechuic acid (92.52 ± 0.45 and 125.50 ± 0.89 µg/g dw) was predominated in M. procera for MA and PT samples, respectively. In general, the results of this comparative study demonstrate that the geographic and climatic conditions of the collection site can influence biomolecule compounds and antioxidant properties of wild mushrooms. This study contributes to the elaboration of nutritional, nutraceutical, and pharmaceutical databases of the worldwide consumed mushrooms.

The article is devoted to the creation of a carbohydrate product with rosehip extract in the form of sweets (glucose Fudge) with a therapeutic and preventive effect aimed at restoring the body of people exposed to intense physical and mental stress and the effects of damaging environmental factors. As carbohydrates in the recipe, simple carbohydrates (glucose) and complex carbohydrates in the form of starch molasses containing (maltose, tri - Tetra - sugars, dextrins) are used. Glucose in the formulation is the main energy ingredient, sweetener and structure-forming component that gives the product a solid consistency due to crystallization. The medicinal effect of the product is provided by rosehip extract. Numerous published studies have established its vitamin, immunostimulating and antioxidant activity, inhibition of uric acid formation and obesity, which are associated with flavonoids, other phenolic compounds, and vitamins. The list of medicinal properties of rosehip extract shows the feasibility of using it in additional nutrition of people in order to prevent diseases. For the formulation of our sweets, the extraction of crushed rosehip fruits was carried out three times with hot water at a temperature of 65-700C, followed by concentration of the extract under vacuum to 25-30% SV. The resulting extract-concentrate was introduced into the formulation in a dosage of 5.5% SV per 100 g of SV glucose Fudge, which provided the necessary dosage for the product when used from 3 (for children) to 10 sweets a day (for adults) for the prevention of colds.
