Preparation of limonin monoclonal antibody and establishment of a sensitive icELISA for analyzing limonin in citrus and herbal samples

Food Chemistry
Limonin is an intensely bitter and highly oxidized tetracyclic triterpenoid secondary metabolite, which is abundant in the Rutaceae and Meliaceae, especially in Citrus. In order to detect limonin content in complex substrates such as citrus and traditional Chinese medicine, monoclonal antibodies specifically recognizing limonin were prepared and an ...

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 ...

Development and validation of a decigram-scale method for the separation of limonin from limonin glucoside by C-18 flash chromatography

Food Chemistry, 2009
A preparative method for decigram-scale polishing of limonin glucoside (1) with regard to removing traces of limonin (2), the main bitter principle in Citrus, is reported. During the method development and up-scaling stages, sample purity, sample size, solvent amounts, and drying conditions were varied.

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
