In this study, fruits, fruit flesh and seeds of damask rose (Rosa damascena Mill.) and rose hip (Rosa canina L.) were assayed for the composition of fatty acids, ascorbic acid, α-tocopherol, β-carotene, and mineral elements. The content of linoleic acid in seed oil of Rosa damascena (54.18%) was found to be higher than in that of Rosa canina (48.84%). α-Tocopherol contents were found to be 7.10 μg/g and 34.20 μg/g for Rosa damascena and Rosa canina fruits, respectively. Ascorbic acid content was determined as the highest in the fruit flesh (546 mg/100 g in Rosa damascena and 2200 mg/100 g in Rosa canina), and as the lowest in the seeds of both species. Rosa damascena fruits were found to be richer in minerals such as Ca, Fe, K, Mn, Na, P, and Zn than Rosa canina fruits. The results of the present study showed that Rosa damascena fruits could be used as food and food additive equally as rose hip fruits.

Edible wild plants were investigated as potential sources of antioxidants and prebiotics to benefit human health. Antioxidant activity, ascorbic acid and total dietary fibre contents were determined in edible wild plants from Lesotho, Swaziland and South Africa. Pure probiotic strains of Bifidobacterium animalis subsp. animalis (ATCC 25527), Lactobacillus rhamnosus (TUTBFD) and Lactobacillus acidophilus (ATCC 314) were cultured in broth containing edible wild plant extracts to assess their prebiotic activity. Cyperus esculantus had the highest arscobic acid content of 603±64.1 mg/100 g edible dry plant material followed by Rosa rubiginosa (500.8±48.8 mg/100 g). The two plants had IC50 of 10.7±0.2 µg/mL and 47.8±0.2 µg/mL for DPPH inhibition, respectively. Forty percent (40%) (n=30) of the edible wild plants had significant (p<0.01) total antioxidant activity (IC50<60 µg/mL) and high ascorbic acid content (>200 mg/100 g). Nasturtium officinale reported the highest yield for soluble fibre (25%) while Hypoxis hirsute had the highest total dietary fibre content (7.3%). Rorippa nudiuscula enhanced the growth of B. animalis significantly (p=0.001), 8-fold more than inulin. Chenopodium album and Urtica dioica stimulated the growth of L. rhamnosus significantly (p=0.0001) than inulin, respectfully, while Tragopogon porrifolius significantly (p=0.0001) stimulated the growth of L. acidophilus than inulin. It was concluded that the investigated edible wild plants from southern Africa have antioxidant and prebiotic properties that may be beneficial to human health.

Wild plants may play an important role in human nutrition and health and, among them, many are the leafy species. We hypothesized that the wild greens could be profitably grown as microgreens and baby greens, specialty products whose market is increasing. We compared three wild leafy species (Sanguisorba minor Scop., Sinapis arvensis L., and Taraxacum officinale Weber ex F. H. Wigg.) harvested at the microgreen and baby green stages. Seedlings were grown hydroponically in a half-strength Hoagland nutrient solution under controlled climatic conditions. At harvest, the yield was assessed, and chlorophylls, carotenoids, anthocyanins, phenolic index, nitrate, and mineral elements were measured in the two types of product. The potential contribution to human mineral intake was calculated, and the possible risk due to the presence of metals potentially detrimental for health was estimated. Results showed that micro/baby greens of the studied wild plants achieved competitive yields and could contribute to the dietary intake of macroelements, microelements, and non-nutrient bioactive compounds. On the other hand, the wild greens showed high amounts of nitrate and traces of some metals potentially detrimental for health, suggesting the need for caution in the use of wild species for producing microgreens and baby leaves.

Leaves, stems, roots, and berries of a number of native plants which were collected in the Ungava Bay region of northern Quebec were analyzed for ascorbic acid (vitamin C) and β-carotene (vitamin A) in a laboratory set up near Fort Chimo.The results indicated that some plants from the Eastern Arctic were remarkably vitamin-rich. These findings demonstrated that wild plants represent a valuable natural resource which might be utilized under survival conditions or as required to ensure proper nutrition in the far North.

Negative Effect

Infants’ high nutritional needs are fulfilled by mother’s milk or infant formulas to provide all the necessary nutrients, among them minerals. Minerals uptake depends not only on mineral content but also on their bioavailability which, in turn, is affected by the different components of the infant formulas. An understanding of these effects would help to improve mineral bioavailability. This work reviews the influence of endogenous (proteins and phytates) and added (ascorbic and citric acid) components in infant formulas on the bioavailability of nutritionally important mineral elements (calcium, zinc, iron and copper) and their interactions. Special attention is given to the influence of protein, which is positive for calcium and negative for iron absorption. The marked negative effect of phytates on iron and zinc absorption can be counteracted by a dephytinization process. Of the added compounds, ascorbic acid has a positive effect on iron absorption that depends on the molar ratio between ascorbic acid and iron. In fact, adding ascorbic acid can counteract the negative effect of phytic acid on iron absorption but does not alter the effect of phytic acid on zinc absorption. The null effect of an increase in citric acid content can be ascribed to the fact that the citrate contents of infant formulas are already high. One of the most important element interactions is the negative effect of calcium on zinc and iron intestinal absorption and also the interaction between zinc and iron. These interactions deserve our attention because these minerals are essential to infants’ growth and development.

Morocco is a traditional supplier of medicinal and aromatic plants to the world. This activity has resulted to the exploitation of wild plants than dried plants for herbal needs and food flavors. Many species are used for the production of plant extracts and other aromatic essences mainly for the pharmaceutical and cosmetics industry. Among these metabolites, there are essential oils that are mixtures of aromatic substances present in the form of tiny droplets in the leaves, fruit peel, resin, branches, and wood. These oils, however, is endowed with antioxidant properties. This study aims to evaluate the antioxidant activity of essential oils of three moroccan aromatic and medicinal plants: Thymus vulgaris, Mentha spicata, and Citrus limonum. The oil extraction was performed by steam distillation in a Clevenger type apparatus. Also, the antioxidant activity of these oils was evaluated by the method of DPPH (2,2-diphenyl-1-picrylhydrazyl), in comparison with the antioxidant synthetic, ascorbic acid. In the present work, the results showed that the antioxidant activity of three essential oils studied by the trapping method of free radical is moderate. Also, the oil of Thymus vulgaris has a strong activity which exceeds that of ascorbic acid. This was followed by the oil of Mentha spicata, while the lowest activity was observed in Citrus limonum.

Celery is one of the major nutraceutical vegetable species due to the high dietary and medicinal properties of all of its plant parts. Yield, growth and produce quality of six celery genotypes belonging to leafy (Elixir and Samurai), stalk (Atlant and Primus) or root (Egor and Dobrynya) types, as well as the distribution of biomass, sugars, mineral elements and antioxidants among the different plant parts, were assessed. Within the celery root type, cultivar Dobrynya resulted in higher yield than Egor, whereas the genotype did not significantly affect the marketable plant part production of leafy and stalk types. Leaf/petiole ratios relevant to biomass, total dissolved solids, sugars, ascorbic acid, flavonoids, antioxidant activity and ash, K, Zn, Fe, Mn, Cu and Se content were significantly affected by the celery type examined. Ash content was highest in the leaves and lowest in the roots. Celery antioxidant system was characterized by highly significant relationships between ascorbic acid, polyphenols, flavonoids, antioxidant activity and Zn. Among the celery types analyzed, the highest values of chlorophyll, Fe and Mn content as well as antioxidant activity were recorded in leaves from root genotypes, which suggests interesting nutraceutical prospects of the aforementioned plant parts for human utilization.

The ascorbic acid content in the leaves of 10 wild plants that grow in New Brunswick was determined at approximately two-week intervals from June to September. 'Free' and 'total' dehydroascorbic acid were measured, using the method of Roe. The total ascorbic acid is highest in young green leaves. After the plants have flowered the ascorbic acid decreases. It becomes almost negligible when the leaves have wilted and turned brown. 'Free' dehydroascorbic acid was present in all 10 plants in small quantity. It fluctuated from time to time but remained fairly constant for all the plants during the period of investigation, and was independent of the 'total' value for that plant. The values for ascorbic acid have been measured for ripe strawberries, for fiddleheads, and for several common vegetables over the same summer months. They have been tabulated for comparison with the values of ascorbic acid of the 10 wild plants.
