The authors elucidated the constituents of the essential oil and the steam nonvolatile oil (fixed oil) from
Elettaria cardamomum Maton.
The nonvolatile oil was treated with 2
N-sodium carbonate solution, and was separated into the two parts; sodium carbonate soluble part and insoluble part.
Each part was investigated by means of column chromatography, gas chromatography, infrared spectrum, mass spectrum, nuclear magnetic resonance spectrum and chemical method.
As a result, following fifty kinds of compound were detected as constituents of the essential oil and nonvolatile oil; α-pinene, camphene, sabinene, myrcene, 1, 4-cineole, limonene, 1, 8-cineole,
p-cymene, methyl heptenone, linalool, linalyl acetate,
cis-
p-2-menthen-1-ol, terpinen-4-ol,
trans-
p-2-menthen-1-ol, β-terpineol, α-terpineol, α-terpinyl acetate, borneol, neryl acetate, geranyl acetate, nerol, geraniol, nerolidol, caprylic acid, capric acid, lauric acid, myristic acid, pentadecanoic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, arachidic acid,
