Organic Acids and Volatile Compounds Isolated from Prunus mume Extract

Among organic acids, Prunus mume extract(PME) was mostly consisted of $0.47\;mg\%$ citric, $0.43\;mg\%$ malic and $0.25\;mg\%$ oxalic acid Volatile compounds in PME were identified by GC/MSD, showing that acetic acid($8.3\%$) and p-coumaric acid($13.1\%$) as well as 5-hydroxymethyl furfural($32.3\%$), furfural($8.3\%$), and 3-methyl-2,3-furandione($2.3\%$) were major compounds which are known as antimicrobial substances.

매실추출물로부터 분리된 유기산과 휘발성분

매실추출물의 이화학적 특성을 조사한 결과, 매실추출물에는 유기산은 $0.47\;mg\%$ citric, $0.43\;mg\%$ malic와 $0.25\;mg\%$ oxalic 함유되어 있었다. 또한, 매실추출물의 휘발성화합물을 GC/MSD로 분리, 동정한 결과, 매실추출물은 항균성물질로 알려진 acetic acid($8.3\%$), ${\rho}$-cumaric acid($13.1\%$)등의 유기산을 다량 함유하고 있었으며, 항균성분으로 알려진 5-hydroxymethyl fufural($32.3\%$), furfural($2.0\%$), 3-methyl-2,3-furandione($2.3\%$) 등도 높은 함량으로 검출되었다.
