limonin/citrus reshni

Delayed bitterness causes severe economic loss in citrus juice industry worldwide, which is mostly due to the formation of limonoid compounds, especially limonin, in juice. In this study, effects of postharvest time of fruits, heat treatment, pH and filtration of juice on limonin content in Newhall

The seeds of Citrus reticulata afforded the new limonoid derivative, isolimonexic acid methyl ether, in addition to the previously isolated limonin, deacetylnomilin, obacunone and ichangin. The structure elucidation was achieved primarily through 1D and 2-D-NMR analyses. The marginal antimalarial

To clone squalene synthase gene( ss) from seeds of Citrus reticulate ‘Dahongpao’,and to analyze its expression and bioinformatics. The technology of RT-PCR was used to clone the gene of Citrus reticulata seeds and analyze its expression at various growing stages. Moreover, the bioinformatics was

Kinnow mandarin (Citrus reticulata Blanco) is a popular citrus crop of northwestern India and it occupies maximum fruit area in Punjab. However, citrus juice processing industry is still suffering from delayed bitterness problem caused mainly by limonoid aglycones such as limonin. In order to study

Bioguided fractionation of the roots of Citrus sinensis (Rutaceae) led to the isolation and identification of five coumarins, namely, clausarin, suberosin, poncitrin, xanthyletin and thamnosmonin, seven acridones, namely, acrimarine B, 2-methoxycitpressine I, citpressine I, buntanine, acrimarine E,

OBJECTIVE To reveal the pharmacological activities of the components for their further utilization and development by studying the chemical constituents of Citrus changshan-huyou. METHODS The structures were determined by repeated silica gel chromatographic separation and spectral

Three limonoids, namely limonin, nomilin and obacunone, were isolated from the seeds of Citrus reticulata [Blanco Coorg Mandarin]. Their structures were confirmed by spectroscopic studies. With 4th instar larvae of mosquito Culex quinquefasciatus, the EC50 for inhibition of adult emergence was 6.31,

To analyze components of Citrus reticulata and salt-processed C. reticulata by ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS), and compared the changes in components before and after being processed with salt. Principal component

Ethylene is commercially used for artificial degreening of early season grapefruits. The present study investigated the effect of degreening and storage period on Star Ruby grapefruit (Citrus paradisi Macf.) bioactive compounds. Freshly harvested grapefruits were degreened in commercial packing shed

Influence of juice extraction methods and pasteurization temperature and time on quality of mandarin (Citrus reticulata Blanco) juice was studied. The experiment consisted of 65 °C pasteurization temperature with 15, 25 and 35 min holding time; 75 °C with 10, 20 and 30 min and 85 °C with 5, 10 and

Grapefruits (Citrus paradisi Macfad) contain several phytochemicals known to have health maintaining properties. Due to the consumer's interest in obtaining high levels of these phytochemicals, it is important to understand the changes in their levels by common household processing techniques.

A preliminary survey demonstrated activity for alpha-D-glucosidase, alpha-D-mannosidase, alpha-L-arabinosidase, beta-D-glucosidase, beta-D-xylosidase, and beta-D-galactosidase in orange fruit flavedo and albedo tissue. alpha-L-Rhamnosidase was not detected. Subsequently, a beta-glucosidase was

The current study was an attempt to elucidate the mechanism of human colon cancer cell proliferation inhibition by limonin and limonin glucoside (LG) isolated from seeds of Citrus reticulata. The structures of purified compounds were confirmed by NMR and quantified using HPLC. These compounds of

Citrus reticulata semen, a traditional Chinese medicinal material, has desirable medicinal and dietary properties. In this study, a method combining ultrahigh-performance liquid chromatography with Q Exactive Orbitrap tandem mass spectrometry was established and validated for the identification and

A systematically chemical investigation of Citrus changshan-huyou Y.B. Chang resulted in the isolation and structure determination of twelve known natural products, including limonoid ( 1 ), nootkatone ( 2 ), scoparone ( 3 ), β-sitosterol ( 4 ), 3,5,6,7,8,3',4'-heptamethoxyflavone ( 5 ), nobiletin (
