The deodorant activity of black cumin (Nigella sativa L.) seed, a spice used to flavor curry and vegetable foods in Southwest Asia, against garlic (Allium sativum L.) organosulfur compounds related to human malodor was evaluated. Black cumin seed essential oil showed remarkable deodorant activity against garlic essential oil. The mode of action of this deodorant activity was presumed to be that black cumin seed essential oil covalently reacted with the organosulfur compounds in garlic. Therefore, thymoquinone, which is a major constituent in black cumin seed essential oil, and allyl mercaptan, which is one of the organosulfur compounds produced by cutting garlic, were reacted in vitro, and the products were purified and elucidated using spectroscopic data. As a result, these substances were identified as different allyl mercaptan adducts to dihydrothymoquinone. This chemical reaction was presumed to play a key role in the deodorant activity of black cumin seed essential oil.

Abstract The enzyme L-methionine-γ-lyase is commonly found in a wide range of bacteria and catalyzes the α-elimination and γ-elimination of L-methionine to produce methyl mercaptan, α-ketobutyrate, and ammonia. Black cumin seed essential oil (BC oil) reportedly exhibits deodorizing activity against methyl mercaptan. Therefore, we hypothesized that BC oil may also suppress methyl mercaptan production. In this study, we aimed to evaluate the inhibitory effect of BC oil on L-methionine-γ-lyase activity in Fusobacterium nucleatum. Recombinant L-methionine-γ-lyase was incubated under appropriate conditions with BC oil and its constituent thymoquinone. To analyze L-methionine-γ-lyase activity, α-ketobutyric acid and ammonia concentrations were determined. The concentrations of α-ketobutyric acid and ammonia were significantly decreased by 10 µg mL−1 of BC oil (P < 0.01) and 16.4 µg mL−1 of thymoquinone (P < 0.05). An enzyme kinetic assay showed a mixed inhibition pattern between L-methionine-γ-lyase and thymoquinone. In conclusion, BC oil not only had a deodorizing effect against methyl mercaptan but also an inhibitory effect on methyl mercaptan production through the suppression of L-methionine-γ-lyase activity. Thymoquinone may be mainly responsible for these effects of BC oil. Thus, application of natural BC oil may be adapted not only for medical use but also in other areas of life.

Black cumin (Nigella sativa L.) is an annual herb of the Ranunculaceae family, which is growing in Mediterranean region and Ethiopia. In Ethiopia the most people are used as household spice preparation and medicinal purpose. In Ethiopia, black cumin varieties are now days released, but there is no as such work on their physiochemical properties avail. This work presents the investigation of the physicochemical properties of the three-black cumin (Nigella sativa L.) verities (Derbera, Dershaye, and Edan). The results of physicochemical properties Derbera is highest in essential oil content (0.7%) and Edane is lowest (0.3%) than other verities and Dershaye is highest in refractive index of essential oil(1.49), refractive index of oleoresin( 1.52%), moisture(8.0%),fat(24.0%),ash(10.45%), protein(20.61%) and lowest in fiber(16.7%) content than other varieties. From this result, Dershaye black cumin Variety, verities show the superior quality in physicochemical properties than the two black cumin verities (Derbera and Edane).
