  Rose, the queen of ornamental plants, is used as a new food source that is rich in nutrients and biologically active compounds in modern cuisine. Despite the popularity of rose flowers in cooking, many rose cultivars and species have not yet been subjected to research on their edibility. So, the present study aimed to determine the nutrients, minerals, and antioxidant compounds of six rose cultivars (‘Hella’, ‘Crimson Siluetta’, ‘Rainbows End’, ‘Dolce Vita’, ‘Samurai’, and ‘Avalanche’) in an experiment based on completely randomized design with three replications. The cultivars were procured at the full-blooming stage at an authentic producer in Tehran province and were transferred to the laboratory in proper packages. The petals were used to determine the nutritional and antioxidant properties. The results showed that ‘Crimson Siluetta’ was the richest in dry matter (22.75%), total phenols (20.20 mg GAE/100 g FW), antioxidant capacity (85.83% DPPH), P (33.48 mg/100 g FW), and Mn (2.76 mg/100 g FW). The best cultivars in vitamin C and anthocyanin were ‘Crimson Siluetta’ and ‘Samurai’, which did not differ significantly from one another. The richest cultivars in total flavonoids, carotenoids, N, and protein were ‘Rainbows End’ and ‘Dolce Vita’. Also, ‘Dolce Vita’ had the highest vitamin A (0.39 µg/100 g FW) and S content (356 mg/100 g FW). The highest fibre, Fe, Zn, Cu, Ca, Mg, Ni, and B were recorded by ‘Hella’, the best cultivar in K, along with ‘Samurai’. All six cultivars were good sources of minerals, nutrients, and antioxidant compounds. Among them, ‘Hella’ was richer in fibre and minerals, ‘Crimson Siluetta’ was richer in antioxidant compounds, and ‘Dolce Vita’ and ‘Rainbows End’ were more affluent in vitamin A and carotenoids, so they are recommended in human food regime as they are good for their health. تفاصيل المقالة

  Edible nuts have an increasing role in human diet. Pistachio is popular but less known kind of edible nut nevertheless it is rich in health benefiting nutrients, minerals, antioxidants and vitamins. This research focused on the concentration of nitrogen (N), phosphorus (P), potassium (K) and calcium (Ca), all of which play a key role in the healthy human nutrition and lifestyle in the kernels of various cultivars and several samples, including “Ahmedaghaii”, “Akbari”( 2 different phenotypes), “Sefid”, “Momtaz” “Kallehghuchi ” ( 3 different phenotype), “Ohadi ( 3 different phenotypes), “Garmeh” “Daneshmandi”, and “Badami zarand” which are most important commercially cultivated pistachio in Iran, also wild pistachios such as Pistacia atlantica, Sub sp. mutica Desf. (Baneh), P. vera variety “Sarakhs” and chance seedling as “Non-grafted trees. The amounts of the nutrient elements as well as protein content in 100 g kernel were eliminated. Protein content for examined cultivars varied form 13.75-28.13 gr/100gr, as well as N: 2.2-4.5 gr/100gr, P: 350-550 mg/100gr, K: 500-1100 mg/100gr and Ca: 40-135 mg/100gr. The results revealed wide variation in mineral content among different species and cultivars. In addition to, the results provided important data on the concentration of some major elements, emphasizing that pistachio kernel can be used as a good source of major elements as huge quantity of kernels produced and disposed in pistachio processing terminals. تفاصيل المقالة
