  • carotenoid composition of marigold Tagetes Erecta flower extract used as nutritional supplement
    Journal of Agricultural and Food Chemistry, 1999
    Co-Authors: Leigh W Hadden, Ruth H Watkins, Luis W Levy, Edmundo Regalado, Diana M Rivadeneira, Richard B Van Breemen, Steven J Schwartz
    Abstract:

    Commercially prepared marigold flower (Tagetes Erecta) extract was saponified and analyzed for carotenoid composition. HPLC analyses were performed on two normal-phase columns (β-Cyclobond and silica) and on a C30 reversed-phase column. The extract contained 93% utilizable pigments (detected at 450 nm), consisting of all-trans and cis isomers of zeaxanthin (5%), all-trans and cis isomers of lutein, and lutein esters (88%). All were identified by chromatographic retention, UV−visible spectra, and positive ion electrospray mass spectrometry in comparison to authentic standards. Contrary to previous findings, insignificant levels (<0.3%) of lutein oxidation products were detected in the saponified extract. This compositional determination is important for the application of marigold extract in nutritional supplements and increases its value as a poultry feed colorant because it contains more biologically useful lutein compounds than previously believed. Keywords: Lutein; marigold (Tagetes Erecta); poultry; f...

  • An Alternative to Synthetic Acid Base Indicator-Tagetes Erecta Linn
    Asian Journal of Research in Chemistry, 2012
    Co-Authors: A. Elumalai, M. Chinna Eswaraiah, Raju Kasarla, Palla Ravi
    Abstract:

    The present work highlights the use of the methanolic extract of the flowers of Tagetes Erecta as an acid-base indicator in acid-base titrations. This natural indicator is easy to extract as well as easily available. Indicators used in titration show well marked changes of colour in certain intervals of pH. Most of these indicators are organic dyes and are of synthetic origin. Today synthetic indicators are the choice of acid-base titrations. But due to environmental pollution, availability and cost, the search for natural compounds as an acid-base indicator was started. Herbal indicators are evaluated by using strong acid-strong base, strong acid-weak base, weak acid-strong base and weak acid weak base. In all these titrations the methanolic extract of the flowers of Tagetes Erecta was found to be very useful, economical, simple and accurate for acid base titration.

  • A CONCISE REVIEW ON Tagetes Erecta
    2012
    Co-Authors: G. Gopi, A. Elumalai, P. Jayasri
    Abstract:

    Medicinal plants have been of great importance to the health care needs of individuals and their communities. The use of herbal preparations made from medicinal plants is widespread in developing countries. The healing powers of traditional herbal medicines have been realized since antiquities. About 65% of the world populations have access to local medicinal plant knowledge system. India is sitting on a gold mine of well-recorded and traditionally well practiced knowledge of herbal medicine. This article discusses about the medicinal values of Tagetes Erecta. In this communication, we reviewed the pharmacological and phytochemistry of Tagetes Erecta and its application in the treatment of various ailments like the flower parts of plants are used as a hepatoprotective, insecticide, anti-oxidants and analgesic. This review discusses the investigation made by various workers related to chemical constituents, pharmacological action and toxicological studies of this plant since years till date.
