The water extract of Cichorium intybus (WECI) showed a remarkable antioxidative effect on LDL, and inhibitory effects on the production of thiobarbituric acid reactive substance and the Degradation of fatty acids in LDL. Vitamin 1 and unsaturated fatty acids in LDL were protected by adding WECI from the effects of metal catalyzed LDL oxidation. From the results obtained, we conclude that LDL oxidation is inhibited in vitro by the addition of WECI, and that LDL is protected by WECI from oxidative attack, as shown by agarose gel electrohporesis.

The roots of Cichorium intybus L. (chicory) have many nutritional qualities and also have been used for health promotion as traditional medicine. The antimicrobial activity of Cichorium intybus L.'s (chicory) ethanol extract on Bacillus cereus ATCC 10876 were investigated using spot on lawn method in this study. Ethanol extract exhibited antimicrobial activities against Bacillus cereus ATCC 10876 with significance. Also, the results produced the larger zones of inhibition against Bacillus cereus ATCC 10876 tested, with increasing concentration of Cichorium intybus L.'s (chicory) ethanol extracts,. Hence, Cichorium intybus L. (chicory) could be served for keeping the safety of various dairy products as natural antimicrobial agents.

This study was carried out with different nitrogen fertilization levels for the purpose of basic information of culture of chicory (Cichorium intybus L. var. foliosum) in Korea. Treatment level of nitrogen fertilization was separated as 0, 10, 20, and 30kgN/10a. Though the apparent growth of chicory was increased as the increasing level of nitrogen fertilization, the deterous effects such as tipburn and bolting were increased. The treatment of 15-25kgN/10a was suitable for the production of chicory having high quality and commercial value.

This study aimed to evaluate the growth of Cichorium intybus, Brassica juncea, and Lactuca sativa at varying seed ratios, and to suggest an efficient management plan for sustainable indoor agriculture systems. It was treated with mixed sowing as follows: 30 chicory seeds (chicory alone: CC), 22 chicory seeds + 8 lettuce seeds (C₃L₁), 20 chicory seeds + 10 lettuce seeds (C₂L₁), 15 chicory seeds + 15 lettuce seeds (C₁L₁) as intraspecies, and 30 mustard seeds (mustard alone: MC), 22 mustard seeds + 8 lettuce seeds (M₃L₁), 20 mustard seeds + 10 lettuce seeds (M₂L₁), 15 mustard seeds + 15 lettuce seeds (M₁L₁) as interspecies. The study identified the competitive response in seed germination between Cichorium intybus and Lactuca sativa, and in the C₃L₁ experimental group, Lactuca sativa had the highest leaf length, root length, chlorophyll content, and fresh weight. Therefore, the higher the ratio of Cichorium intybus, the higher the growth and productivity of Lactuca sativa; however, higher the ratio of Lactuca sativa, the lower the growth of Cichorium intybus. Furthermore, the nitrogen and potassium content in the substrate was the highest in the C₃L₁ experimental grorp which had the highest seeding rate of the Cichorium intybus. Comparing the groups Brassica juncea and Lactuca sativa, the higher the seeding ratio of Lactuca sativa, the higher the growth and productivity of Brassica juncea. Therefore, a companion seeding of Brassica juncea and Lactuca sativa is beneficial; this could be effective in having a high seeding ratio of Lactuca sativa.

Cichorium intybus (Compositae) has been used for fevers, dyspepsia, headache and jaundice, as a demulcent. Also, it has relaxation effects and relief effects against coffee and teas, and is widely used as food. We investigated anti-lipid peroxidative effects and liver protective activity on $CCl_4$ induced lipid peroxidation and hepatotoxicity in rats. MeOH Ex. enhanced the inhibition of anti-lipid peroxidative effects in liver lipid. In chemical parameters obtained from serum analysis, MeOH Ex. revealed significant decrease on hepatotoxicity. The results were as follows; 1. The inhibitory effects of lipid peroxidation were shown in accordance with the increase of samples' concentration level. 2. In chemical parameters obtained from serum analysis, the activities of GOT, GPT, AlP were restored to near the normal level. The contents of cholesterol and BUN showed inhibitory effects with valence. 3. The weights of liver and spleen were not able to restore to the normal level. But on a general level, they were reduced more than the control group.

Two known eudesmanolides, magnolialide and artesin, were isolated from the roots of Cichorium intybus. Their structures were confirmed by HMBC and NOESY NMR spectral interpretation. Therefore, guaianolides and eudesmanolides that have been previously reported should be revised.

Continuation of a phytochemical study of Cichorium intybus L. (Astraceae) growing in Egypt, resulted in the isolation and identification of a new sesquiterpene lactone 3,4-dihydrolactucin, in addition to the eight known compounds; kaempferol, isoscutellarin, cichoriin, umbelliferone, lupeol, lupeol acetate, ${\beta}-sitosterol$, and ${\beta}-sitosterol-3-O-glucoside$. Chemical structures of the isolated compounds were assigned based on different physical, chemical, and spectroscopic techniques including IR, UV, MS, 1D- and 2D-NMR spectra. Furthermore, the antimicrobial, and spasmogenic activities of some fractions and isolates were also assessed.

We investigated the effect of aqueous extract of Cichorium intybus (CIAE) on mast cell-mediated immediate type allergic reactions. CIAE dose-dependently inhibited systemic anaphylactic reaction induced by compound 48/80 in mice. Especially, CIAE inhibited compound 48/80-induced anaphylactic reaction 100% with the dose of 1000 mg/kg. CIAE 1000 mg/kg also significantly inhibited local anaphylactic reaction activated by anti-dinitrophenyl (DNP) IgE. When mice were pretreated with CIAE at a concentration ranging from 0.1 to 1000 mg/kg, the plasma histamine levels were reduced in a dose-dependent manner. CIAE (1 to 1000 g/ml) dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. These results indicate that CIAE inhibits mast cell-mediated immediate-type allergic reactions.

Objective: Oxidative stress has been suggested as a possible mechanism for the adverse effects of heavy metal toxicity on male reproduction. Cichorium intybus L. is used in Iranian folk medicine as a hepatoprotective agent as well as for its supposed fertility-enhancing properties. The present study was performed to investigate whether the ethanolic extract of C. intybus leaves could protect male rats against lead-induced testicular oxidative stress. Methods: In this experimental study, adult Wistar rats were treated with 0.1% lead acetate in drinking water alone or with 50, 100, or 200 mg/kg body weight of C. intybus extract via gavage once daily for 70 days. The weight of their reproductive organs, levels of serum hormones, histometric parameters of the seminiferous tubules, epidydimal sperm quality, and oxidative stress status were evaluated. Results: The testis weight, seminiferous tubule diameter, epididymal sperm count, serum testosterone level, and testicular levels of superoxide dismutase and glutathione peroxidase were significantly reduced (p< 0.05) in the lead-treated rats. Moreover, significantly (p< 0.05) higher levels of malondialdehyde were observed in the lead-exposed group compared to the control. However, the co-administration of C. intybus ethanolic extract in lead-treated rats was associated with a significant improvement in reproductive parameters. Conclusion: We conclude that C. intybus leaf extract has the potential to prevent lead-induced testicular toxicity and to suppress the adverse effects of lead on male reproductive health.
