| Abstract: | Solvent‐free solid injection was applied to differentiate between wild and cultivated South Korean medicinal foods, including dureup (Aralia elata ), deodeok (Codonopsis lanceolata ) and doraji (Platycodon grandiflorus ). A number of compounds were identified in wild and cultivated dureup (53 and 46), deodeok (47 and 51) and doraji (43 and 38). Secondary metabolites, including butanal,2‐methyl‐, β ‐caryophyllene, neoclovene, α ‐humulene, γ ‐curcumene, β ‐bisabolene, and phytol, were identified in dureup with significantly (P < 0.05) different amounts between both types. In deodeok, squalene and other main components such as acetic acid, methyl ester, furan‐methyl‐furfural, 2‐furan‐methanol, and 5‐methyl‐furfural, were statistically different between the two types. Doraji has significantly different compounds such as furfural, 5‐methyl‐furfural, 2‐methoxy‐phenol, 2‐methoxy‐4‐(1‐propenyl)‐phenol, and 1‐(4‐hydroxy‐3‐methoxyphenyl)‐2‐propanone. Although we failed to confirm the key compounds, a new compound, namely desaspidinol, was synthesized for the first time and its retention index determined under the experimental conditions. This solventless, easy technique can be used as a simple way to discriminate between wild and cultivated types of medicinal plants via identification of volatile markers or specific fingerprints. |
