As the presence of health-promoting substances has become a significant aspect of tomato fruit appreciation, this study investigated nutrient solution salinity as a tool to enhance carotenoid accumulation in cherry tomato fruit (Solanum lycopersicum L. cv. Juanita). Hereby, a key objective was to uncover the underlying mechanisms of carotenoid metabolism, moving away from typical black box rese...

The relationship between carotenoid accumulation and the expression of carotenoid biosynthetic genes during fruit maturation was investigated in three citrus varieties, Satsuma mandarin (Citrus unshiu Marc.), Valencia orange (Citrus sinensis Osbeck), and Lisbon lemon (Citrus limon Burm.f.). We cloned the cDNAs for phytoene synthase (CitPSY), phytoene desaturase (CitPDS), zeta-carotene (car) des...

The characterization of a novel mutant, named Pinalate, derived from the orange (Citrus sinensis L. Osbeck) Navelate, which produces distinctive yellow fruits instead of the typical bright orange colouration, is reported. The carotenoid content and composition, and ABA content in leaf and flavedo tissue (coloured part of the skin) of fruits at different developmental and maturation stages were ...

OBJECTIVE To investigate the usefulness of serum carotenoids as biomarkers of fruit and vegetable consumption. DESIGN : Reproducibility study on three repeat measurements of serum carotenoids. Correlation analysis of carotenoids and dietary food intake, and regression analysis of potential predictive parameters for serum carotenoid levels. SETTING New York, USA. SUBJECT : Women participat...

Loquat (Eriobotrya japonica Lindl.) can be sorted into red- and white-fleshed cultivars. The flesh of Luoyangqing (LYQ, red-fleshed) appears red-orange because of a high content of carotenoids while the flesh of Baisha (BS, white-fleshed) appears ivory white due to a lack of carotenoid accumulation. The carotenoid content in the peel and flesh of LYQ was approximately 68 μg g(-1) and 13 μg g(-1...

Antipyretic effect of ethanolic extract of the leaf of plumeria rubra was investigated. Intraperitoneal administration of boiled milk at a dose 0.5 ml/kg body weight in albino rabbit leads to pyrexia. Intraperitoneal (i. p. route) administration of ethanolic extract of the leaf of plumeria rubra at a dose 200mg/kg body weight were shown significantly reduce the elevated body temperature of rabb...

Qin C.G., Li Y., Niu W.N., Ding Y., Shang X.Y., Xu C.L. (2011): Composition analysis and structural identification of anthocyanins in fruit of waxberry. Czech J. Food Sci., 29: 171–180. Anthocyanin pigments in the fruit of waxberry (Myrica rubra Sieb. et Zucc.), were extracted with 0.1% HCl in ethanol, and the crude anthocyanin extract was purified by C18 Sep-Pak cartridge open-column chromatog...

BACKGROUND Tomatoes provide a significant dietary source of the carotenoids, lycopene and β-carotene. During ripening, carotenoid accumulation determines the fruit colors while chlorophyll degradation. These traits have been, and continue to be, a significant focus for plant breeding efforts. Previous work has found strong evidence for a relationship between CYC-B gene expression and the orange...

Abscisic acid (ABA) plays important roles during tomato fruit ripening. To study the regulation of carotenoid biosynthesis by ABA, the SlNCED1 gene encoding 9-cis-epoxycarotenoid dioxygenase (NCED), a key enzyme in the ABA biosynthesis, was suppressed in tomato plants by transformation with an RNA interference (RNAi) construct driven by a fruit-specific E8 promoter. ABA accumulation and SlNCED1...

The aim of this research was to obtain antioxidant active component from Papuan red fruit oil waste using Ultrasound-assisted extraction. done started the making oil, extraction and bioactive analysis (total tocopherol betacaroten) spectrophotometry. result shows that process contains high amount yield at 20 minutes time with total carotenoid 20, 23 ppm absorbance 1.04. Ultrasound assisted meth...
