AI Article Synopsis
- The essential oil from black cumin (Nigella sativa) was found to effectively deodorize methyl mercaptan, a compound responsible for bad breath.
- After purification, thymoquinone was identified as the primary compound responsible for this deodorizing effect.
- The study suggests that the deodorizing action may occur by the reactive quinone molecule from black cumin interacting with methyl mercaptan.
Article Abstract
A deodorizing substance in black cumin (Nigella sativa L.), a spice for curry and vegetable foods in Southwest Asia, was examined. The essential oil prepared from the seeds of this plant exhibited strong deodorizing activity against methyl mercaptan, which is a main factor in oral malodor. After purification with silica gel column chromatography, the active substance in black cumin seed oil was identified as thymoquinone. This monoterpenic quinone functions as the main deodorizing substance in this oil against methyl mercaptan. Metabolite analysis suggested that the deodorizing activity may be generated by the addition of a reactive quinone molecule to methyl mercaptan. In the present study, the menthane-type quinone and phenol derivatives exhibited deodorizing activities via this mechanism.
