Dihydrochalcone C-glycosides from Averrhoa carambola leaves
Phytochemistry, 2020Ten undescribed dihydrochalcone C-glycosides, carambolasides R1‒R3, S1, S2, T1‒T3, 3-hydroxycarambolaside T1, and 3-hydroxycarambolaside P were isolated along with carambolasides I and P from the leaves of Averrhoa carambola L. (Oxalidaceae). Their structures were determined by spectroscopic and chemical methods.

Harvest Maturity Influences Fruit Quality of Carambola (Averrhoa carambola L.)
Journal of Horticultural Science & Technology, 2020Harvest maturity determines the shelf life and nutritional quality of fruits. The present study was planned to determine the effect of harvest maturity on fruit quality of carambola. Fruits of carambola (Averrhoa carambola L.) cv. “Arkin” were harvested at five maturity stages, i.e., M1 (100% green), M2 (75% green and 25% yellow), M3 (50% green and 50%

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 ...

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.

PROCESSING AND QUALITY EVALUATION OF A CARAMBOLA DRINK (.AVERRHOA CARAMBOLA)
2001The objective of the study was to utilise carambola fruits in drinks and to investigate the quality changes on storage at 10 °C and 25 °C for 5 weeks. A survey was conducted by 125 questionnaires to guide the objectives of the research. Carambola drinks of 4 treatments (9 % and 12% sucrose with or without 3% orange juice) were processed with 0.2 ...

Phytoextraction of Cd-contaminated soil by carambola (Averrhoa carambola) in field trials
Chemosphere, 2009Use of metal-accumulating woody species to extract metals from heavy metal contaminated soil has received more attention. While considerable studies have focused on the phytoextraction potential of willow (Salix spp.) and poplar (Populus spp.), similar information is rare for other woody species.

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 ...

Pectic type II arabinogalactans from starfruit (Averrhoa carambola L.)
Food Chemistry, 2016A structural characterization of polysaccharides from edible tropical fruit named starfruit (Averrhoa carambola L.) was carried out. After the purification steps, two homogeneous fractions were obtained. Fraction 50R was composed of rhamnose, arabinose, galactose and uronic acid in 4.3:56.2:37.4:2M ratio, respectively and fraction 10R was composed of ...

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%).
