The effects of nutrients and cell aggregate size on the cell growth of D. carota and the biosynthesi of carotenoid were investigated. Highest carotenoid content was obtained with sucrose as a carbon source and the equal ratio of ammonium to nitrate. High phosphate concentration stimulated the carotenoid biosynthesis in D. corota. 2,4-D inhibited the cell growth but stimulated the specific carotenoid content at high concentration. By modifying the medium composition based on these findings, three times higher specific carotenoid content and 2.5 times higher total carotenoid content were obtained as compared with the results obtained with basic MS media. Biosynthesis of carotenoid was found to be affected by cell aggregate size; high carotenoid production was obtained from the large aggregated cells resulted from high sucrose concentration.

BACKGROUND: Kale (Brassica oleracea) biosynthesizes various phytochemicals including glucosinolates, flavonoids, and carotenoids. Phytochemicals of plants are influenced by light, temperature, carbon dioxide, and growing conditions. Specifically, carotenoids are affected by temperature, light, and oxygen. The aim of this study was to investigate the effect of cold stress (day/night: $25^{\circ}C/20^{\circ}C$, $20^{\circ}C/15^{\circ}C$, $15^{\circ}C/10^{\circ}C$) on carotenoids in kale leaves. METHODS AND RESULTS: Kale was grown in pots for up to 50 days after sowing (DAS) in a greenhouse. For cold acclimation experiments, kale grown in growth chambers for 3 days and was subjected to low temperature for 4 days. The conditions maintained in the growth chambers were as follows: photoperiod, 12/12 h (day/night); light, fluorescent; and relative humidity, 60%. Carotenoid (lutein, ${\alpha}-carotene$, zeaxanthin, ${\beta}-carotene$) contents were analyzed by high-performance liquid chromatography (HPLC). The total carotenoid content gradually increased during cold acclimation for 3 days. When kale was subjected to cold stress, the total carotenoid content was high at $25^{\circ}C/20^{\circ}C$ treatment, but low at $15^{\circ}C/10^{\circ}C$ treatment. The total carotenoid content of kale leaves continuously grown in greenhouse decreased from 50 to 57 DAS (1,418 and 1,160 mgkg-1 dry wt., respectively). The lutein, ${\alpha}-carotene$, and ${\beta}-carotene$ contents were very low and the zeaxanthin contents were very high at $15^{\circ}C/10^{\circ}C$ treatment. When kale was subjected to cold stress, the ratio of individual to the total carotenoid contents of kale leaves was 4553% for -carotene and 210% for zeaxanthin. CONCLUSION: The ${\beta}-carotene$ and zeaxanthin contents in kale leaves indicate their sensitiveness toward cold stress.

Carotenoid-rich foods focus one's attention on the prevention age-related diseases. This study was conducted to investigate the carotenoid status and look into the factors that affect the bioavailability of carotenoid in 121 elderly nonsmoking Korean women. Carotenoids and lipids in plasma, and nutrient intakes including carotenoid were studied. The mean plasma total-cholesterol, HDL-cholesterol, LDL-cholesterol and triacylglycerol concentrations were 220.0 mg/dl 49.5mg/dl , 139.2mg/dl and 157.4mg/dl , respectively. Significantly positive correlations were found between the plasma lutein + zeaxanthin, lycopene and $\beta$-carotene concentrations and the intake of fruits (r=0.17, r=0.20, r=0.19). However, significantly negative correlations were found between the plasma zeaxanthin, and $\beta$-carotene concentrations that adjusted for carotenoid intakes and intakes of vegetables (r=-0.21, r=-0.19), and between plasma lutein＋zeaxanthin, lycopene and $\beta$-carotene concentrations that adjusted for carotenoid intakes and intakes of fruits (r= -0.21, r=-0.18, r=-0.24). After the adjustment for plasma lipids, there was no correlation between the plasma carotenoid concentrations and the carotenoid-rich foods. However, after adjustment for fiber intake, significantly strong positive correlations were found between the plasma carotenoid concentrations and carotenoid-rich foods. The plasma levels of carotenoid biomarkers (plasma carotenoid concentrations adjusted for dietary fiber intakes) decreased with age, and the plasma levels of lycopene biomarkers (plasma lycopene concentrations adjusted for dietary fiber intakes) increased with regular exercise. However alcohol drinking had no impact. These results suggested that age, physical activity, and dietary fiber intake affected the bioavailability of carotenoid. Therefore, when the elderly have carotenoid-rich foods, they should consider ways of increasing the bioavailability of carotenoid through cooking methods and Physical activity.

This study was performed as a part of comparative biochemical studies of carotenoid pigment for the fresh water fish. Carotenoids in integument of Korean dark sleeper, Odontobutis platycephala, and dark sleeper, Odontobutis odontobutis interrupta, which are all the Korean native fresh water fish, were separated by thin layer chromatography, column chromatography and HPLC. The separated carotenoid were then reduced and isomerized by NaBH4 and I2 respectively to investigate UV-Vis spectrophotometeric patterns and chracterized by IR, 1H-NMR and Mass spectrum. The content of total carotenoids in the integument of Korean dark sleeper was 3.01mg% in April, but it was increased to 3.74mg% in September at the near of spawning period. The carotenoid isolated in April consisted of $\beta$-carotene(25.6%), lutein(18.5%) and zeaxanthin(12.0%) as major carotenoids and also contained isocryptoxanthin, diatoxanthin, tunaxanthin, cynthiaxanthin, canthaxanthin and $\alpha$-cryptoxanthin as minor carotenoids. Similarly, in September the carotenoid consisted of $\beta$-carotene(16.5%), zeaxanthin(13.7%) and cynthiaxanthin(13.6%) as major carotenoids and also contained lutein, isocryptoxanthin, tunaxanthin, $\alpha$-cryptoxanthin, diatoxanthin and canthaxanthin as minor carotenoids. At the near of spawning period, the content of cynthiaxanthin and $\alpha$-cryptoxanthin were increased. The content of total carotenoids in the integument of spawning period. T도 carotenoid isolated in April and September consisted of $\beta$-carotene(24.9%, 27.5%), zeaxanthin(14.4%, 20.9%) and lutein(12.6%, 11.4%) as major carotenoids and also contained cynthiaxanthin, tunaxanthin, diatoxanthin, isocryptoxanthin, $\alpha$-cryp-toxanthin and canthaxanthin as minor carotenoids. At the near of spawning period, the content of zeaxanthin was increased, indicating that the carotenoid composition were dependent upon their living conditions and their integument colors. Both Korean dark sleeper and dark sleeper contained high amount of cynthiaxanthin and diatoxanthin which are found as rare carotenoids in the other of fresh water fish. It is interes that they also contained tunaxanthin which is a specific carotenoid in marine fishes.
