Li, Pei-Xia published the artcileChemical constituents analysis of ethyl acetate extract from MSR-1707 by GC-MS, SDS of cas: 929-77-1, the main research area is chem constituent analysis ethyl acetate extract MSR.
To analyze the chem. constituents of Et acetate extract from MSR-1707 to promote the rational utilization of the mushroom resources. MSR-1707 belongs to the genus Nigrospora sp. It was extracted by Et acetate, then the extract was analyzed by Gas Chromatog.-Mass Spectrometer (GC-MS). Identification of compounds was achieved according to their GC retention indexes (RI) and database search using the library of NIST05, as well as a comparison of the fragmentation pattern of the mass spectra with data published in the literature. Seventy-three compounds were separated by gas chromatog. Based on the NIST05 spectral library and corresponding literature information, fifty-three compounds were identified. Their relative percentage of contents accounted for 95.62% of the outflow peak. Some of the identified peaks are 9-Octadecenoic acid, Me ester(E)(18.50%),9-Tricosene(Z)(8.30%), 13-Docosenamide (E)(5.26%) and Myristic acid glycidyl ester (3.11%). This is the first report of chem. constituents of the Et acetate extract of Nigrospora sp. using GC-MS, which offer some theor. basis for the further exploration and application of this mushroom.
Asian Journal of Biology published new progress about Analysis. 929-77-1 belongs to class esters-buliding-blocks, name is Methyl docosanoate, and the molecular formula is C23H46O2, SDS of cas: 929-77-1.
