| Title : | THE CONTENT OF ESSENTIAL ELEMENTS IN THE FLOWERS AND FRUITS OF CHAENOMELES (Chaenomeles Lindl.) |
| Abstract : | Chaenomeles sp. (C. cathayensis, C. japonica, C. spesiosa and C. x superba) are characterized by rich chemical composition of all plant parts and the wide variability of the accumulation of separate components in different species and cultivars. For the expansion of ideas about the chaenomeles content nutritional value of 7 essential macro- and microelements in the flowers and fruit of 8 cultivars from the Nikita Botanical Gardens collection have been studied. Analysis of plant samples was carried out by dry ashing with subsequent determination of mostelements on the atomic absorption spectrophotometer. Ca and Mg were determined by complex metric method. It was revealed that essential elements were accumulated in the flowers and fruits in different quantities. The maximum amount of K, Fe, Mg, Zn, Cu and Mn is contained in the flowers. The largest amount of Ca was detected in fruits, whereas Zn, Mn and Cu were most presented in seeds. The studied cultivars differ significantly in accumulation of essential elements. According to the studied complex components, the accession P-8-3 was allocated. Flowers were characterized by the highest content of Ca, Zn, Mn, Cu and high content – of K; fruits were rich in K, Ca, Zn, Mn and Cu. In the jam from the chaenomeles fruit, the high content of K (2087 mg 100 g-1, i.e. more than 2%) was revealed. It is seven fold higher than daily rate for human. Thus, chaenomeles flowers, fruits and seeds are a valuable raw material, enriched with vital macro- and microelements. |
