Sea-buckthorn is an important species especially in terms of land reclamation, but it has also an appreciable commercial value. The aim of this review paper was to highlight the multiple uses of this shrub species across world. Data regarding taxonomy, chorology, ecological requirements and biological characteristics were also presented. Special attention has been given to the role of sea-buckthorn in land reclamation. The importance of this species is expected to increase in the future due to its high ecological amplitude and biological characteristics that make it suitable for many types of land, including arid terrains.
The aim of the study was to determine contents of phytosterol and oxyphytosterols in soybean oil and soybean oil with the addition of sea buckthorn seed oil after thermal processing, and to assay the oxidative stability of the oils. The analysis verified that the thermal processing of soybean oil at 120°C induced a decrease in total phytosterols (phytosterols concentration was reduced by 5.2 to 21.0%) and formation of the following phytosterol oxidation products: 7-ketositosterol, 5α,6α-epoxysitosterol, 7-ketocampesterol, 5α,6α-epoxycampesterol, 7-ketostigmasterol, and 5α,6α-epoxystigmasterol. The content of phytosterol oxidation products (POPs) increased with the higher sea buckthorn seed oil addition to soybean oil (from 1.2 mg/100 g in soybean oil with 1% addition of sea buckthorn oil to 11.4 mg/100 g in soybean oil with 5% addition of sea buckthorn oil) during Rancimat test.
The investigations were carried out on the common sea buckthorn (Hippohaë rhamnoides L.) growing in the coastal areas of the Baltic Sea. The performed analyses comprised the determination of the basic chemical composition and selected heavy metals. For comparative purposes, investigations were also conducted on wood of the common sea buckthorn growing in urban conditions, namely in the city of Poznań. On the basis of the performed experiments it was found that the content of cellulose in the examined material ranged from 33.6 to 39.3% with the highest values determined in the wood of bushes growing in urban conditions. In addition, considerable differences were also observed in the lignin content in the compared samples, whereas the concentration of pentosans remained at the level of 18% irrespective of the place of sample collection. Concentrations of the examined heavy metals did not exceed levels dangerous for the growth and development of the examined bushes.
The aim of the study was to verify the usability of sea buckthorn (Hippophae rhamnoides L.) fruit from the cultivars grown in Poland for the manufacturing fruit and fruit-vegetable puree juices. Juices were made from sea buckthorn puree which had been obtained by straining the scalded fruit pulp. Juices with the best organoleptic properties were obtained under laboratory and pilot-plant conditions. The sea buck­thorn content in juices never exceeded 16%. The scope of investigation covered the analysis of key qualitative features of the buckthorn puree and of selected juice sam­ples, which were later stored in darkness at room temperature. Composition of four different sea buckthorn cultivars were analysed in the study: 'Prozracznaja', 'Botani- czeskaja-Lubitelskaja', 'Luczistaja' and 'Botaniczeskaja'. 'Botaniczeskaja-Lubitelskaja' turned out to have the highest total sugar (3.71%) and ascorbic acid content (82.3 mg/100 ml), as well as the highest antioxidant capacity (9.85 ^mol Trolox/100 ml). The highest content of carotenoids was notedin 'Prozracznaja' (9.97 mg/100 ml). Orange-sea buckthorn juice had the most ascorbic acid (31.56 mg/100 ml) and phenolic compounds (62.5 mg/100 ml). Tomato-sea buckthorn juice was richest in carotenoids content (5.15 mg/100 ml).
The purpose of the seabuckthorn breeding program in the Institute for Fruit Growing in Samokhvalovichy, near Mińsk (Republic of Belarus) is to create varieties combining high productivity, good taste qualities and characters, determining suitability for machine harvesting and male varieties. The first hybrids were received from the open pollination of the cultivars Botanicheskaya, Podarok sadu, Otradnaya, Trophimovskaya by A.I. Batchylo in 1992. The promising male forms 01-43-95, 16-01-95, 11-04-96, 04-17-96 characterized by winter hardiness and guaranteed good pollination of the female varieties were selected for further estimation. On the results of the primary study a male cv. Gaspadar (hybrid 11-04-96) was recommended for the State Variety Trial in 2005. Since 1997 more than 50 combinations of crossbreeding have been carried out and about 30 thousands of seedlings estimated at the selection nurseries and orchards in Institute for Fruit Growing in Samokhvalovichy in 1998-2008. The promising hybrids 10-02-01-98, 14-24-99, 03-22-00, 06-40-00, 13-26-01, 02-51-01, 07-51-01, 10-51-01 were selected for further research. All the selected hybrids were characterized by winter hardiness, dry pull-out character and had no visual wilt symptoms. Hybrids 10-02-01-98, 06-40-00 were of a low height (1.5-1.8 m) and pull-out force 1.55 H. To introduce new parental forms for the breeding process the examination of wild sea buckthorn plantations at the territory of South Warmia of Poland (Olsztyn, Poland) was carried out in 2006 and 7 selected female forms and 1 male form were chosen for breeding.
Zbadano frakcję lipofilną owoców 6 odmian rokitnika pod wzglądem zawartości tokoferoli i karotenoidów. W badanych odmianach zaobserwowano duże zróżnicowanie ogólnej zawartości karotenoidów i tokoferoli. Analiza chromatograficzna (HPLC) potwierdziła różnice odmianowe w składzie ilościowym i jakościowym karotenoidów i tokoferoli. Ponadto, ustalono zależność pomiędzy zawartością karotenoidów, a zdolnością wychwytywania rodnika DPPH poprzez frakcję lipofilną.
This paper presents the cold pressing method of obtaining juice from sea buckthorn berries, and oil from sea buckthorn seeds. Different types of pulp processing was performed: with enzymatic treatment of pulp or without enzymatic treatment as well. The seeds preparation before cold pressing was also carried out in two variants.
This paper describes chemical composition of the sea buckthorn fruits with particular attention paid to bioactive substances. The sea buckthorn fruits are a valuable sourge of carotenoids, tocopherolsvitamin C, organic acids and micro- and macroelements. Therapeutic properties of these fruits and their preserves were underlined.
