Observations regarding mericarp and seedling variability by Daucus carota L. Ssp. Carota  [cached]
anonymous UNDERGRADUATE STUDENT
Notulae Botanicae Horti Agrobotanici Cluj-Napoca , 1981,
Abstract: Related with possible evolutionary connections between the different populations of wild and cultivated carrot (Daucus carota L. ssp. Carota and ssp. Sativa/ Hoffm./ Aro.), mericarp and seedling variability by two different groups of wild carrot populations collected in Transylvania (Eastern Europe) and Germany (Central Europe) have been studied. A marked variability was observed in the coloration of the hypocotyls region of the seedlings. Seed characters were not sufficient for the detection of a variability pattern. A marked variation pattern was observed in juvenile stage: populations from Germany or that from carrot growing regions of Transylvania developed more vigorous roots. This indicates the existence of possible evolutionary pressure acting on the wild populations through the gene flow from the cultivated taxa.

International Journal of Biomedical and Advance Research , 2010, DOI: 10.7439/ijbar.v1i3.4
Abstract: Objective: Hypolipidemic activity of ethanolic extract of Daucus carota seeds in Normal rats. Method: Rats were divided in to 4 groups. First control group, treated with vehicle only for 7 days. Second group was standard, treated with lovastatin (7.2mg/kg) for 7 days. Third and fourth group were test, treated with Daucus carota seeds extract (200mg/kg and 400mg/kg) for 7 days. 8th day blood sample was collected by retro orbital route and lipid profiles were estimated in serum. Result and Conclusions: Standard and test (400mg/kg DCSE) groups were showed significant (P <0.001) reduction in the total cholesterol, triglyceride HDL and VLDL as compared control group. Test group (200mg/kg) was showed significant (P <0.05) reduction as compared control group. The antioxidant potential of Daucus carota seeds has contributed to the reduction of oxidative stress and Lipid levels in experimental rats.

Abstract: Daucus carota L. (Apiaceae), is used in the traditional medicine for the treatment of gastric disorders viz., acidity and gastric ulcers. The present study was undertaken to determine the gastroprotective potential of the fresh juice extract of the roots of Daucus carota. The juice extract of the roots of Daucus carota (DCE) was tested orally at the dose of 200 and 400 mg/kg body weight, on gastric ulceration experimentally induced by pylorus ligation, aspirin and ethanol induced. The parameters considered to assess the anti-ulcer activity were volume of gastric secretion, pH, free acidity, total acidity, mucus content and ulcer index. The DCE at the dose of 200 and 400 mg/kg, significantly decreased gastric volume, free acidity, total acidity and ulcer index, while it increased the pH and the mucus content as compared with control. The DCE at a dose of 400 mg/kg produced 60.45, 56.80 and 43.51 % significant inhibition when gastric ulceration were induced by pylorus ligation, aspirin and ethanol, respectively. The DCE possesses gastroprotective property and the results supported traditional uses of the roots of this plant in the treatment of gastric ulcer and acidity.

Abstract: Experiments were carried out for optimization of conditions for morphogenic callus production and regeneration of carrot (Daucus carota L.) using four cultivars cultivated in Iran. Hypocotyl segments were put on media supplemented with 0.2 mg·L-1 2,4-D for callus initiation and proliferation. Small portions of callus (25 mg) were cut and transferred to new media with different concentrations of 2,4-D including 0.2, 0.5 and 1 mg·L-1. MS (Murashige & Skoog 1962) and MSm (Masuda et al. 1981) media were used in the experiments to identify the differences between these two media according to callus, embryoid and plantlet production. Obtained results showed that low level of 2,4-D (0.2 mg·L-1) was more effective in morphogenic callus production although higher amounts of it (0.5 mg·L-1 and 1 mg·L-1) caused more callus growth. Kinetin in concentration of 0.1 mg·L-1 was more effective for regeneration than BAP used in concentration 1 mg·L-1 especially according to embryoid production. MSm medium was more useful than MS for callus production and regeneration of carrot plantlets. Among tested cultivars Nantes Improved had more capability to produce viable plantlets.

Molecules , 2009, DOI: 10.3390/molecules14082862
Abstract: Phytochemical investigation of the fruits of Daucus carota L. resulted in the isolation of a new sesquiterpene named as daucucarotol (1). Its structure was elucidated on the basis of 1D and 2D NMR experiments, coupled with MS studies. To our knowledge, compound 1 is the first example for a natural eudesmane sesquiterpene with a hydroxymethyl group located at a methine carbon rather than a usual quaternary carbon in the two fused six-membered ringsystems.

Ferraz, Helena M. C.;Bianco, Graziela G.;Bombonato, Fernanda I.;Andrade, Leandro H.;Porto, André L. M.;
Química Nova , 2008, DOI: 10.1590/S0100-40422008000400020
Abstract: the bioreduction of a series of substituted a-tetralones, carried out using daucus carota root (carrot), afforded the corresponding homochiral a-tetralols in variable conversions (9 to 90%) and excellent enantiomeric excesses. two of the assayed a-tetralones were resistant to the bioreduction conditions. the absolute configurations of four a-tetralols were assigned as being (s), by comparison to the (s)-enantiomers obtained by kinetic resolution promoted by calb-catalysed acetylation. additionally, the new 5-methoxy-6-methyl-1-tetralone was synthesized in seven steps from 3-methylsalicylic acid.

D Puchooa, R Ramburn
African Journal of Biotechnology , 2004,
Abstract: Effects of using carrot juice in the in vitro growth of Daucus carota were investigated. Callus was the only form of growth obtained after five weeks in culture. The increase in fresh weight, dry weight and moisture content of the explants with increasing concentration of carrot juice in the medium was much lower when compared to either the cytokinin benzyladenine (BA) and/or the auxin picloram. Spectrophotometric and chromatographic analyses revealed the presence of both indole-3-acetic acid (IAA) and abscissic acid (ABA) in the carrot juice, while gibberellic acid was absent. Key Words: Carrot juice; auxin; abscissic acid. African Journal of Biotechnology Vol. 3 (4), 2004: 248-252

Pakistan Journal of Biological Sciences , 2006,
Abstract: Three anthocyanin pigments were isolated from black Carrot root (Daucus carota L.). Cationexchange resin column, TLC analysis, UV-visible spectrophotometry and proton NMR spectroscopy studies indicated the presence of nonacylated compound 1 is β-D-glucopyranosyl-(1>6)-[ β-D-xylopyranosyl-(1>2) ]-β-D-galactopyranosyl-(1>O3)-cyanidin. Acylated compounds 2 and 3 are 6-O-acyl-β-D-glucopyranosyl-(1>6)-[ β-D-xylopyranosyl-(1>2) ]-β-D-galactopyranosyl-(1>O3)-cyanidins. Anthocyanins 2 and 3, respectively, were acylated with 2-methoxycinnamic acid and 4-hydroxy-3, 5-dimethoxycinnamic acid (sinapic acid). Monomeric anthocyanin content was determined by pH-differential. There was 434.85±1.3 mg kg-1 dry matter (cyanidine-3-glucoside base).

Abstract: In this paper the heavy metal uptake of carrot (Daucus carota) is studied in sample areas with different soil types. Our aim is to examine how the different soil types possessing different characteristics affect the heavy metal uptake and distribution in the plant. Correlation analyses were carried out in order to determine which of the total heavy metal concentrations and soil characteristics(pH, CaCO3-content, humus content, granulometric composition) play the most important role in the uptake of the Co, Cu, Fe, Ni, Mn, Zn and in the metal distribution in the examined plant. Soil and plant samples were collected from 5 different Hungarian areas in July, 2008. In the cases of soils with different soil characteristics, the examined plants are supposed to give varied physiological responses.During the examination we proved that the genetic type and the heavy metal content of the soil do not significantly affect the heavy metal uptake of carrot. The granulometric composition of the soil has the most considerable effect but this factor only affects the rate of the metal uptake in 50% of the examined heavy metals (Ni, Mn, Zn).
