This paper is to provide reference for chem. composition anal. in Angiopteris fokiensis. The fat-soluble components in A. fokiensis were extracted and separated The separated fat-soluble compounds were analyzed and identified by GC-MS after Me esterification. Totally 52 compounds were detected and 43 compounds of those were identified. They were mainly organic acids and sterol-like compounds The 43 components are first identified in A. fokiensis. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Application In Synthesis of Methyl nonadecanoate).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application In Synthesis of Methyl nonadecanoate
