A liquid chromatog.-quadrupole time-of-flight mass spectrometry (LC-QTOF/MS) based plant metabolomics approach was established to investigate the metabolic profiles of the Cinnamomum camphora leaves of four different areas. The LC-QTOF/MS data were subjected to principal component anal. (PCA) and orthogonal partial least squared discrimination anal. (OPLS-DA) to find the potential characteristic components of C. camphora leaves from the four areas in a quick way. C. camphora leaves from different areas could be separated into four different groups chem. according to the PCA scores. The chem. constituents in C. camphora leaves from four areas were obviously different. The potential markers were identified by comparison with the reference compounds or were tentatively assigned by matching the retention time, empirical mol. formula and fragment ions with those of the published compounds of C. camphora leaves. The proposed anal. method is fast, accurate and reliable for differentiating C. camphora leaves from different areas. Moreover, this study supplied a new method for the quality evaluation of other medicinal materials. In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxybenzoate (cas: 118-61-6Application In Synthesis of Ethyl 2-hydroxybenzoate).
Ethyl 2-hydroxybenzoate (cas: 118-61-6) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Ethyl 2-hydroxybenzoate
