Carotenoids of the fruit of Averrhoa carambola
Phytochemistry, 1983Abstract The carotenoids of the tropical fruit Averrhoa carambola were investigated and from most of them mass spectra were taken. The total carotenoid content was 22 μg/g fr. wt. The carotenoid pattern was uncommon, the main pigments were phytofluene (17%), ζ-carotene (25%), β-cryptoflavin (34%) and mutatoxanthin (14%).

Phytotoxic Constituents of the Fruits of Averrhoa carambola
Chemistry of Natural Compounds, 2015The agrochemical industry is continuously searching for phytotoxic compounds, including weedicides, herbicides,etc. The continuous use of synthetic phytotoxic compounds may affect nontarget organisms and also cause environmentalpollution problems due to retarded degradation, etc.

Additional volatile constituents of carambola (Averrhoa carambola L.) fruit
Flavour and Fragrance Journal, 1989AbstractThe volatiles of fresh carambola (Averrhoa carambola L.) were separated from the fruit pulp by high‐vacuum distillation and subsequent solvent extraction (pentane‐dichloromethane, 2:1). In three fractions obtained by preseparation of the concentrated extract with adsorption chromatography on silica gel (pentane‐diethyl ether gradient) the ...

Enzymatic carotenoid cleavage in star fruit (Averrhoa carambola)
Phytochemistry, 2003This paper presents the first description of an enzyme fraction exhibiting carotenoid cleavage activity isolated from fruit skin of Averrhoa carambola. Partial purification of the enzyme could be achieved by acetone precipitation, ultrafiltration (300 kDa, 50 kDa), isoelectric focusing (pH 3-10) and sodium dodecyl sulfate polyacrylamide gel ...

Mechanisms of star fruit (Averrhoa carambola) toxicity: A mini-review
Toxicon, 2020The star fruit (Averrhoa carambola) is consumed in high amounts in Asia and Central/South America. It contains oxalic acid and caramboxin. In some individuals, its ingestion may lead to nephrotoxicity and neurotoxicity. The nephrotoxic effect is due to oxalate deposition in renal tubules resulting in acute tubular necrosis and interstitial nephritis ...

Dihydroabscisic alcohol from Averrhoa carambola fruit
Phytochemistry, 1994Abstract (1′ S ,4 E )-2,3-Dihydroabscisic alcohol has been identified in an ether extract of starfruit ( Averrhoa carambola ). After purification by multilayer coil countercurrent chromatography (MLCCC) and HPLC, the structure of the new ABA derivative was elucidated by 1 H and 13 C NMR spectroscopy.

Three groups of carambola fruits (Averrhoa carambola L.) were stored at 2 and 10 degrees C (85-90% relative humidity). The major physicochemical, physiological, and enzymatic responses of fruit were measured in each group over a 30-day period: chilling injury index (CII), decay (%), intracuticular waxes, cuticle permeability, pulp firmness, weight loss,

PHYTOCHEMICAL STUDIES OF STAR FRUIT AVERRHOA CARAMBOLA L.
INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH, 2021The paper deals with a phytochemical investigation on the fruit of Averrhoa carambola L. belonging to the family Oxalidaceae. Commonly known as “star fruit”. Fruits and leaves are used widely in Ayurveda preparations to pacify impaired Kapha, pitta, skin diseases, pruritis, worm infestations, diarrhea, vomiting, hemorrhoids, intermittent fever, over ...

Abstract Artificially induced polyploid crops are generally associated with improved agronomic characteristics. Triploids and tetraploids previously created from the diploid carambola (Averrhoa carambola L.) cultivar 'B17′ (2n = 22) were used as experimental materials.
