Evaluation of the Antioxidant Capacity of Limonin, Nomilin, and Limonin Glucoside

Journal of Agricultural and Food Chemistry, 2006
The antioxidant capacity (AOC) of three representative citrus limonoids, limonin, nomilin, and limonin glucoside, was examined by the oxygen radical absorbance capacity (ORAC), Trolox equivalent antioxidant capacity (TEAC), beta-carotene-linoleic acid bleaching, and 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging assays.

The structure of limonin

Experientia, 1960
Die Struktur desepi-Limonol-jodoacetates (C26H31O8) COCH2I, wurde durch dreidimensionale Rontgenanalyse bestimmt. Es gelang, die Lage samtlicher Atome in zwei kristallographisch unabhangigen, jedoch chemisch identischen Molekeln zu ermitteln. Dieses Resultat stellt eine vollstandige Bestimmung der Konstitution und der Stereochemie des Limonins dar.

Gender differences in limonin pharmacokinetics in rats

European Journal of Drug Metabolism and Pharmacokinetics, 2005
In the present study, the pharmacokinetics of limonin (LM) were investigated in male and female rats. LM concentrations in the plasma were determined after the oral administration of 36 mg/kg LM or after intravenous (i.v.) injection of LM 3.6 mg/kg respectively.

Limonin ameliorates cardiovascular dysfunction and remodeling in hypertensive rats

Life Sciences, 2023
Limonin is a tetracyclic triterpenoid isolated from citrus fruits. Here, the effects of limonin on cardiovascular abnormalities in nitric oxide-deficient rats induced by Nω-Nitrol-arginine methyl ester (L-NAME) were explored.Male Sprague Dawley rats were given L-NAME (40 mg/kg, drinking water) for 3 weeks and then treated daily with polyethylene glycol

Degradation of limonin by entrappedRhodococcus fascians cells

Biotechnology Letters, 1989
Limonin degradingRhodococcusfascians was immobilized by entrapment in alginate, k-carrageenan, agarose and polyacrylamide gels. Except this latter, gels were used both with and without polyethyleneimine treatment followed by glutaraldehyde crosslinking.

An Improved Enzyme Immunoassay for Limonin

Journal of Food Science, 1988
ABSTRACT Performance of the previously reported enzyme immunoassay for determination of limonin in citrus juice was improved by stabilization of anti‐limonin‐antibody‐coated microtitration wells with 1% solution of ovalbumin and polyvinyl alcohol.

A limonin‐degrading enzyme in citrus albedo

Journal of the Science of Food and Agriculture, 1971
AbstractExperiments are described which demonstrate the presence in the albedo of Navel and Valencia oranges of a system with the properties of an enzyme capable of degrading limonin, the bitter principle of orange juice.

Radioimmunoassay for the determination of limonin in Citrus

Phytochemistry, 1980
Abstract An 125 I-radioimmunoassay technique has been developed for the triterpenoid bitter principle, limonin. Synthesis of the iodinated tracer and the limonin—bovine serum albumin conjugate are described. The antibody has a high affinity ( K a 1.1 x 10 9 l/mol) and specificity for limonin and the detection limit of the assay is 0.07 ng or 0.7 ...

Removal of limonin from bitter orange juice

Journal of the Science of Food and Agriculture, 1968
AbstractPolyamides are shown to be effective adsorbents for removal of the bitter principle, limonin, from pasteurised Washington Navel orange juice. The extent of limonin removal varies with different juices, but sufficient can be removed by one or two treatments to bring the concentration below the organoleptically detectable level.

Stability of limonin glucoside in beverage matrices

Journal of the Science of Food and Agriculture, 2008
AbstractBACKGROUND: We completed a study over a 200‐day period examining the stability of limonin glucoside formulated into three beverage matrices.RESULTS: Beverages containing limonin glucoside were found to contain limonin (0.13–20.10 mg L−1) during their initial testing; however, these concentrations were directly attributable to the presence of ...
