Increase in lutein and zeaxanthin content in the eggs of hens fed marigold flower extract
Marigold flower extract (MFE), a natural source of xanthophylls, was added to the diets of hens at different concentrations (0, 150, 250, and 350 mg/kg of diet) to determine the effects of MFE on hen performance, physical characteristics of egg quality, and carotenoid content of the egg yolk of hens housed in enriched cages. Additionally, the highest dose of MFE (350 mg/kg) was tested under com...
متن کاملEnzyme-Assisted Oil Extraction of Lutein from Marigold ( erecta) Flowers and Stability of Lutein
Marigold (Tagetes erecta) flowers are a rich source of organic solvents. In this study, lutein was extracted from marigold flowers with enzyme extraction without using organic solvents. Extraction produced oil that contained 0.36 mg/ml lutein (present as lutein esters but calculated as free lutein), and the yield was comparable to solvent extraction. The oil containing lutein was used to produc...
متن کاملDietary Lutein Attenuates Bleomycin-Induced Pulmonary Fibrosis in Mice
Idiopathic Pulmonary Fibrosis is a chronic lung disease characterized by lung inflammation and progression to fibrosis. Anti-fibrotic efficacy of lutein was studied in mouse model of bleomycin induced pulmonary fibrosis. The mice were orally administrated with 100 or 200 mg/kg of lutein three days prior to intra-tracheal instillation of bleomycin on day 0 and continued up to day 21. Total cell ...
متن کاملShelf stability of lutein from marigold (Tagetes erecta L.) flowers in vegetable oils
The stability of lutein in sunflower and rice bran oils was investigated in the temperature range 25–40 °C. Experiments were made using a standardized plant extract at 5% by weight of lutein derived from the flowers of Tagetes erecta L. Samples of the pigment in oil were incubated at each temperature for up to 10 days and the time course of degradation was monitored. A kinetic analysis of the d...
متن کاملAntioxidant and Skin Anti-Aging Effects of Marigold Methanol Extract
The objective of this study was to evaluate the antioxidant and anti-aging effects of marigold methanol extract (MGME) in human dermal fibroblasts. Total polyphenolic and flavonoid contents in MGME were 74.8 mg TAE (tannic acid equivalent)/g and 85.6 mg RE (rutin equivalent)/g, respectively. MGME (500 μg/mL) increased 1,1-diphenyl-2-picryl hydrazyl (DPPH) and 2,2'-azino-3-ethylbenzothiazoline-6...
