Many human cancer cell lines which have been maintained in fetal bovine serum (FBS)-supplemented medium produce and secrete many substances such as transferrin, alpha 1-antitrypsin, alpha 2-macroglobulin, alkaline phosphatase, gamma-glutamyltranspeptidase, creatine kinase, carcinoembryonic antigen,
The effects of dietary lutein from marigold extract on the development and growth of a transplantable murine mammary tumor and on lymphocyte function were investigated. Mice were fed a diet containing 0.1% or 0.4% of lutein. In experiment 1, mice were fed the diets for 3 weeks and infused with
The recent development of powerful "omics" technologies (genomics, transcriptomics, proteomics, metabolomics, and lipidomics) has opened new avenues in nutritional sciences toward precision nutrition, which is a genotype-directed nutrition that takes into account the differential responses
Ten oleanane-type triterpene glycosides, 1-10, including four new compounds, calendulaglycoside A 6'-O-methyl ester (2), calendulaglycoside A 6'-O-n-butyl ester (3), calendulaglycoside B 6'-O-n-butyl ester (5), and calendulaglycoside C 6'-O-n-butyl ester (8), along with five known flavonol
High levels of dietary lutein can inhibit mammary tumor growth in mice. However, the antitumor effect of low levels of dietary lutein on mammary tumors is unavailable. Female BALB/c mice and the WAZ-2T (-SA) mammary tumor cell line were used in two experiments. A preliminary tumor cell dose
Tagetones A (1) and B (2), two new monocyclic diterpenoids were isolated from the n-hexane fraction of fresh flowers of Tagetes minuta L. (Asteraceae). Their structures were established by multiple spectroscopic methods (IR, HR-ESI-MS, and 1D-, and 2D-NMR), in addition to comparison with literature
Tagetes patula is used to treat cancer patients in alternative healthcare systems. However, its cytotoxic and genotoxic effects have not been reported. Therefore, themethanol extract of T. patula flower, the ethyl acetate fraction, and the pure compound patuletin were evaluatedusing
Marigold (Tagetes erecta) is an Asteraceous plant of industrial, ornamental and medicinal importance. Tagetes erecta species, popularly known as marigold, is grown as ornamental plant and is adapted to several agro climates. Inflorescences have been utilized as pigment source for food coloring,
The essential oil from the leaves of Tagetes minuta L., growing wild in Yemen, was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. A total of 28 compounds were identified representing 74.2% of total oil composition. Major components of the essential oil were
The principal natural food colorants used in modern food manufacture are anthocyanins, betalains, carotenoids, chlorophylls, riboflavin and caramel. Carotenoids (carotenes and xanthophylls) occur naturally in some foods such as carrots, red tomatoes, butter, cheese, paprika, palm oil, corn kernels,
Marigold (Tagetes erecta L.) has long been used as a medicinal herb for a number of therapeutic activities. In the present study, the cytotoxicities of ethanol and ethyl acetate extracts of marigold flowers and their inhibitory effects on elastase and tyrosinase enzymes were investigated. An MTT
High dietary intake of lutein has been associated with risk reduction of many chronic diseases, including age-related macular degeneration (AMD), cancer, and cardiovascular diseases. Lutein in food is generally regarded as safe. However, information on the toxicological and beneficial effect of
BACKGROUND
The search for newer compounds against pathogenic species continues unabated due to drug resistance. Traditionally, Tagetes erecta Linn. (Compositae) has been used for the treatment of various parasitic and microbial diseases.
OBJECTIVE
To evaluate the antioxidant activity of the ethanol
Phytochemical investigation of the n-hexane fraction of the methanolic extract of Tagetes minuta L. (Asteraceae) aerial parts afforded a new thiophene derivative: thiotagetin A (3), together with β-sitosterol (1) and stigmasterol (2). The structure of the new thiophene was identified by UV, IR, 1D
Yellow and orange egg yolks are good sources of xanthophyll carotenoids, consumption of which is associated with health benefits, such as cancer prevention, eye health, and bone health. Industrial feed fortificants used to improve egg yolk color and carotenoid concentration typically are derived
