Waste and by-products as sources of lycopene, phytoene, and phytofluene - Integrative review with bibliometric analysis

Food Research International, 2023
Food loss and waste are severe social, economic, and environmental issues. An example is the incorrect handling of waste or by-products used to obtain bioactive compounds, such as carotenoids. This review aimed to present a comprehensive overview of research on lycopene, phytoene, and phytofluene obtained from waste and by-products.

A Carotenoid Algal Preparation Containing Phytoene and Phytofluene Inhibited LDL Oxidation In Vitro

Plant Foods for Human Nutrition, 2008
The antioxidative effect of the carotenoids phytoene and phytofluene in biological systems has not yet been studied. We therefore sought to investigate the effect of these carotenoids, isolated from the alga Dunaliella bardawil, in a biological system and used the in vitro low density lipoprotein (LDL) oxidation method to assay their antioxidative ...

Phytoene, phytofluene and ζ-carotene isomers from a Scenedesmus obliquus mutant

Phytochemistry, 1977
Abstract A number of mutant strains of the green alga, Scenedesmus obliquus , when grown in the dark, accumulated ζ-carotene as their major carotenoid together with appreciable concentrations of phytoene and phytofluene. The phytoene was almost entirely the 15- cis isomer, and phytofluene was also present mainly as the 15- cis form, whereas the ζ ...

Contribution of violaxanthin, neoxanthin, phytoene and phytofluene to total carotenoid intake: Assessment in Luxembourg

Journal of Food Composition and Analysis, 2011
Abstract Dietary carotenoid intake has been associated with a low incidence of several chronic diseases, including cardiovascular complications, cancer, and macular degeneration. While food composition and intake of some carotenoids such as β-carotene and lycopene is frequently available, information on the contribution of less studied ...

Effect of individual and combined supplementation of phytoene, phytofluene, and lycopene against nicotine-induced pancreatic islet cell dysfunction

Toxicology and Environmental Health Sciences, 2020
To understand the capability of carotenoids phytoene, phytofluene, and lycopene supplementation individually and in combination to counter the effect of nicotine-induced oxidative stress-mediated pancreatic islet dysfunctioning. Thirty male Wistar albino rats were divided into six groups: Group A, control; Group B, treated with intraperitoneal ...

Stereocontrolled synthesis of the di-cis-pentaene chromophore found in phytofluene from tangerine tomato fruits

Tetrahedron Letters, 1979
The di-cis-pentaene chromophore found in natural phytofluene (2) from Tangerine tomatoes has been synthesised by judicious choice of phosphine oxide anion intermediates and conditions for their reactions with unsaturated aldehydes.

The roles of isomers of phytoene, phytofluene and ?-carotene in carotenoid biosynthesis by a mutant strain of Scenedesmus obliquus

Archives of Microbiology, 1977
Considerable changes in pigment composition occur during a period of 10 h when dark-grown cultures of PG1, a zeta-carotenic strain of Scenedesmus obliquus, are illuminated. These changes are consistent with a biosynthetic pathway in which 15-cis-phytoene is converted via 15-cis-phytofluene and 15-cis-zeta-carotene into all-trans-zeta-carotene and trans-

ChemInform Abstract: STEREOCONTROLLED SYNTHESIS OF THE DI‐CIS‐PENTAENE CHROMOPHORE FOUND IN PHYTOFLUENE FROM TANGERINE TOMATO FRUITS

Chemischer Informationsdienst, 1980
AbstractDurch Wittig‐Kondensation von Phosphinoxid (I) mit dem ungesättigten Ketoester (II) entsteht (III), das mit Lithiumalanat und Braunstein zum ungesättigten Aldehyd (IV) führt, dieser kann mit dem aus trans, trans‐(E)‐Farnesylchlorid hergestellten Phosphinoxid (V) zu (VI) kondensiert und dann mit NaH in den definierten ungesättigten ...
