Two Chinese black cardamom oils (Amomum tsao-ko) were analyzed using GC and GC/MS and compared to 2 Indian cardamom oils from the species Amomum subulatum and Elettaria cardamomum, resp. The main constituents of A. tsao-ko oils were eucalyptol, geranial, geraniol, trans-2,3,3A,7A-tetrahydro-1H-indene-4-carbaldehyde, (2E)-decenal, neral, and 4-indanecarbaldehyde. Special attention was given to the 1H-indene-carbaldehyes, which are frequently wrongly assigned in previous literature. A detailed odor evaluation of the oils was also carried out. In addition, composition variations of 28 main constituents of 8 E. cardamomum oils were investigated, taking various factors like origin, production methods, plant material, and drying stage into consideration. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Application of 112-14-1).
Octyl acetate (cas: 112-14-1) 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. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
