Six naphthyridine isomers are white solids with a surprisingly wide span of melting points: 1,6-Naphthyridine’s is the lowest at <40 ºC; 2,6-naphthyridine’s is the highest at 114–115 ºC. Very few metal complexes of naphthyridines other than 1,8-naphthyridine have been described.Recommanded Product: 42971-09-5

Natural products research is the most enormous field of research in terms of the amount of data and importance of information. Natural products discovery and metabolomics deals with a crucial mode of representation of the profile of biol. active metabolites. In this regard, the profiling of the chem. makeup of complex natural plant extracts necessarily requires employing sophisticated and advanced anal. methods like RP-HPLC-ESI-Q-TOF-MS as well as data mining and processing methods. The genus Garcinia (Clusiaceae) contains phenolic, flavonoids, xanthones, triterpenes, and benzophenones which have been reported for their significant biol. properties. Due to its high content of secondary metabolites and its large domestic usage, we have developed a simple, rapid and precise method to characterize all the secondary metabolites using Reverse-Phase Ultra Performance Liquid Chromatog. coupled to Electrospray Ionization Quadruple Time-of-Flight Mass Spectrometry (RP-HPLC-ESI-Q- TOF-MS) for the hydro-methanolic extract A total of about 3443 secondary metabolites from the fruit and 3757 secondary metabolites from the seed were identified by the Progenesis-QI data anal. Among these a total of 74 compounds from fruits and 86 polar compounds from seeds were manually identified using the mass error limit of < ± 5 ppm including the score less than 40. The unexplored bioactives belonging to the class of glycosides, flavones, xanthones, organic acids and other phenolic derivatives Garcinia xanthochymus was found to contain significant number of diverse phytochem. components. These results indicate the profile of mols. present in G. xanthochymus and will be helpful for industries and researchers involved in isolation of their mols. of interest. In the experiment, the researchers used many compounds, for example, (41S,13aS)-Ethyl 13a-ethyl-2,3,41,5,6,13a-hexahydro-1H-indolo[3,2,1-de]pyrido[3,2,1-ij][1,5]naphthyridine-12-carboxylate (cas: 42971-09-5Recommanded Product: 42971-09-5).
