Although the bioactive compounds in goji have been thoroughly identified and quantified, little information is available on the bitter compounds in the berries, and no systematic works on the substances responsible for their bitterness have been performed. Herein, the substances contributing to the bitterness of berries were isolated and purified from bitter-tasting goji by the combined use of column chromatog. and high-pressure liquid chromatog. (HPLC). The bitterness of the isolated compounds was evaluated using a biosensor with immobilized rat taste-bud tissues. The structures were elucidated via comprehensive mass spectrometry (MS) and NMR (NMR) analyses. Seven spermine or spermidine alkaloids were identified, including four new compounds (lyciamarspermidines A and B and lyciamarspermines A and B). The intensities of the bitterness levels of the isolated compounds differed with the number of glucose substituents. These isolated compounds all contribute to the bitterness of goji. The results of this study provide opportunities for the further investigation of the bitterness of goji. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Product Details of 126-14-7).
(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives.Tetrahydrofuran has many industry uses as a solvent including in natural and synthetic resins, high polymers, fat oils, rubber, polymer. Tetrahydrofuran reaction with hydrogen sulfide: In the presence of a solid acid catalyst, tetrahydrofuran reacts with hydrogen sulfide to give tetrahydrothiophene.Product Details of 126-14-7
