매실추출물의 이화학적 특성을 조사한 결과, 매실추출물에는 유기산은 citric, malic와 oxalic 함유되어 있었다. 또한, 매실추출물의 휘발성화합물을 GC/MSD로 분리, 동정한 결과, 매실추출물은 항균성물질로 알려진 acetic acid(), -cumaric acid()등의 유기산을 다량 함유하고 있었으며, 항균성분으로 알려진 5-hydroxymethyl fufural(), furfural(), 3-methyl-2,3-furand

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