NUTRITIONAL CAROTENOIDS AND THEIR IMPLICATION IN HUMAN HEALTH<br />
limited information on carotenoids in wild berries we aimed to<br />
determine β-carotene and xanthophylls content in northern berries.<br />
Four berry species (Rubus chamaemorus, Vaccinium myrtillus,<br />
Vaccinium vitis-idaea, Oxycoccus palustris) were selected for this<br />
study in taiga zone of European North-East of Russia. Samples were<br />
collected in August-September 2010 and transported to laboratory,<br />
where they were quick-freezed and kept at -76°C. Carotenoids in<br />
freeze-dried samples were extracted with acetone. Individual<br />
carotenoids were separated using reversed-phase high-performance<br />
liquid chromatography (HPLC) system (Knauer, Germany), a column<br />
4.0×250 mm Diasphere-110-C18NT. The pigments were eluted<br />
for 34 min with gradient solvent systems A<br />
(acetonitrile:methanol:water, 75:12:4, v/v) and B (methanol:ethyl<br />
acetate, 68:32, v/v) at a flow rate of 2 ml/min. Identification of<br />
carotenoids was carried out by comparing of HPLC retension times<br />
with corresponding standarts. The highest total carotenoids content<br />
among the studied berries was found in cloudberry (2840 μg/100 g<br />
DW) followed by blueberry (2140 μg/100 g). Cranberry and cowberry<br />
had the lowest carotenoid content, accordingly 210 and 150<br />
μg/100 g DW. All berries had β-carotene but this carotenoid prevailed<br />
greatly in cloudberry (82% of total carotenoids content).<br />
Lutein was a principal carotenoid in blueberry (71%). The major<br />
contributors to the total carotenoids content of cranberry were βcarotene<br />
(28%), lutein (23%) and neoxanthin (20%). Not great quantity<br />
of violaxanthin cycle carotenoids (violaxanthin, antheraxanthin<br />
and zeaxanthin) were identified in all berries and cloudberry sepals.<br />
It was established that the carotenoid HPLC profiles of the<br />
extracts from cloudberry are complex, because the naturally occurring<br />
carotenoids (lutein, zeaxanthin, and violaxanthin) in these fruits<br />
are esterified with straight chain of fatty acids. Unidentified<br />
carotenoid constituents were presented in the unsaponified extract<br />
of cloudberry. The received results are meant a regional database of<br />
resources with increased nutritional value.<br />

The aim of this study was to compare the content of carotenoids in<br />
seventeen cultivars of carrots grown in Poland. We compared conventional<br />
orange cultivars with rarely grown: white, yellow and purple<br />
with creamy core cultivars. Carrots are an important source of<br />
carotenoids (mainly β-carotene) in daily diet. In Poland, the carrot is<br />
grown on a large scale (813 000 tons) and has great economic<br />
importance. New cultivars introduced into crops are not only different<br />
in shapes and colors, but also in the content of bioactive and<br />
important for health compounds including carotenoids.<br />
Seventeen selected cultivars of carrots were grown on plots<br />
at the Experimental Station of Agricultural University in<br />
Mydlniki. For determine the content of carotenoids, extracts<br />
made from lyophilized carrot roots were analyzed by spectrophotometric<br />
as well as HPLC methods with DAD detector. The<br />
highest content of carotenoids was found in cultivars: 'Kazan'<br />
and 'Kongo' (nearly 10 mg/100 g f.w.). We also compared the<br />
antioxidant properties of selected cultivars using the FRAP<br />
method (Benzie and Stain, 1996).<br />

Carotenoids are needed in human diet as provitamin A. It is<br />
less known that they significantly contribute to the protection of<br />
membrane lipids as important antioxidants soluble in fats.<br />
Carotenoids as antioxidant compounds reduce the risk of chronic<br />
diseases (cardiovascular diseases, cancer ect.) (Krinsky and<br />
Yeum, 2003, Stahl and Sies, 2003). Identifying the Daucus carota<br />
L. cultivars with the highest carotenoid content in roots will<br />
make it possible to recommend them for cultivation, especially<br />
for farms specializing in production of preserves with high<br />
carotenoid content and contribute to further selection of new cultivars<br />
in horticultural breeding.<br />

The aim of the present study was to compare flower carotenoid<br />
extracts with regard to their phytochemical profiles and their in<br />
vitro anti-Helicobacter pylori (H. pylori), cytotoxic, multidrug<br />
resistance (MDR) reversal and radical scavenging activity.<br />
Carotenoid composition was investigated in the different fractionation<br />
of rose hips, using extraction methods. Six main<br />
carotenoids – epimers of neochrome, lutein, zeaxanthin, rubixanthin,<br />
lycopene, β, β-carotene – were identified from Rose hips by<br />
their chromatographic behavior and UV-visible spectra, which is<br />
in accordance with other studies on carotenoids in this plant<br />
material. The active principles in the carotenoid extract might differ,<br />
depending upon the extraction procedures.<br />
