Deodorizing Effect of Rubus suavissimus Extract against Allyl Methyl Sulfide

Abstract

The deodorizing activity of various kinds of plant extracts on allylmethylsulfide (AMS) in the breath after eating garlic was measured by gas chromatography. Among these extracts, water extract of Rubus suavissimus (RSW) showed the highest deodorizing activity against AMS. The active components of R. suavissimus were considered to be a mixture of polyphenolic compounds, because of positive correlation with deodorizing activity and polyphenol content in RSW. As a result of the separation of RSW in guidance with deodorizing activity by column chromatography of Diaion HP20 and Sephadex LH-20, the fraction RSW-24 possessed the highest deodorizing effect. And allylmethylsulfoxide was detected in the reaction mixture of AMS and RSW-24. The deodorizing activity of RSW-24 was disappeared under anaerobic conditions. It was suggested that the reaction mechanism of RSW against AMS was the oxidative reaction by polyphenolic compounds.
