Deodorant Effect of Plant Extracts of the Family Rosaceae against Methyl Mercaptan

Abstract

Six species of herbs of the family Rosaceae were extracted with water, 50% ethanol solution, or ethanol. The extracts were assayed by gas chromatography for methyl mercaptan (CH3SH) to search for oral deodorizers more effective than sodium copper chlorophyllin and tea catechins. Lignt extracts (water and 50% ethanol extracts of blackberry leaves, raspberry leaves, rose petals, and wild strawberry leaves and fruits)deodorized CH3SH. Of these extracts tested, the water extract of raspberry (Rubus idaeus) leaves was the strongest deodorant. The active components of raspberry leaves seemed to be a mixture of polyphenol compounds, mainly ellagitannins. © 1992, Japan Society for Bioscience, Biotechnology, and Agrochemistry.
