Halitosis is mainly caused by the presence of volatile sulfur-containing compounds (VSC's) produced by proteolytic periodontopathic bacteria in the oral cavity. Various mouth-rinses have been offered on the market as solutions to reduce halitosis. The aim of this study was to find a potent substance for the prevention of halitosis. The halitosis prevention substance (HPS) from cumin seed powder was purified by solvent extraction, silica gel column chromatography and preparative TLC to yield an oil phase (0.98%). Instrumental analysis such as FT-IR, $^1H$-NMR and $^{13}C$-NMR showed that HPS contained an -OH group, -HC=CH-, -COO-, and long chain acyl group. HPS was therefore determined to be 2-hydroxyethyl-${\beta}$-undecenate. HPS inhibited the growth of Fusobacterium nucleatum and Porphyromonas gingivalis, by 72.44% and 64.37% at $1{\times}10^{-2}\;M$, and by 99.85% and 91.62% at $5\;{\times}\;10^{-2}\;M$, respectively. It also inhibited the activity of L-methionine-${\alpha}$-deamino-${\gamma}$-mercaptomethane-lyase (METase), which was produced by oral microbes. Furthermore, the VSC production by oral microbes in the human mouth air decreased with increasing HPS concentration. These results suggested that HPS from cumin seed is an efficient halitosis prevention agent.

The antimite activities of cumin seed oil-derived cuminaldehyde and eleven commercial components of Cuminum cyminum oil were examined against Dermatophagoides farinae and Dermatophagoides pteronyssinus adults and compared with those of benzyl benzoate and N,N-diethyl-m-toluamide. Responses varied according to dose and mite species. On the basis of $LD_{50}$ values, the compound most toxic to D. farinae adults was cuminaldehyde ($2.40\mug/cm^2$) followed by benzyl benzoate ($9.32\mug/cm^2$), thymol ($9.43\mug/cm^2$), DEET ($36.84\mug/cm^2$), and 3-carene ($42.11\mug/cm^2$). Against D. pteronyssinus adults, cuminaldehyde ($1.94\mug/cm^2$) was much more effective than benzyl benzoate ($6.50\mug/cm^2$) thymol ($6.92\mug/cm^2$), DEET ($17.79\mug/cm^2$), and 3-carene ($39.85\mug/cm^2$). These results indicate that the antimite activity of cumin seed oil could be caused by cuminaldehyde. Cuminaldehyde was about 3.9 and 3.4 times more toxic than benzyl benzoate against D. farinae and D. pteronyssinus adults, respectively. Therefore, further study is needed to confirm the findings of this study and the possibility of cuminaldehyde as a house dust mite control agent or a lead compound.

This study was to assess the antimicrobial action of 2-hydroxyethyl ${\beta}$-undecenate purified from cumin (Cuminum cymium L.) seed against the oral anaerobe, Streptococcus mutans, which is associated with gingivitis, specifically focusing on the catabolic effect. 2-Hydroxyethyl ${\beta}$-undecenate inhibited the acid production and growth of S. mutans after 30 hr incubation at 50 mM. The glycolysis of S. mutans with glucose as substrate was similarly sensitive to 2-hydroxyethyl ${\beta}$-undecenate, with 70% inhibition of glucose utilization at 5 mM and 90% inhibition at 50 mM. In addition, this substance potently inhibited the glycolysis enzyme, glyceraldehyde-3-phosphate dehydrogenase (GADP); the phosphoenolpyruvate, glucose phosphotransferase (Glucose-PTS); and membrane ATPase, in a concentration dependent manner. The $IC_{50}$ values for inhibition of GADP, Glucose-PTS, and ATPase were 1, 0.9, and 5 mM, respectively. Furthermore, 2-hydroxyethyl ${\beta}$-undecenate inhibited teeth calcium ion elution by 80% at 50 mM. These results suggest that 2-hydroxyethyl ${\beta}$-undecenate is a potent inhibitor of carbohydrate metabolism and the growth of S. mutans JC-2.

The present study was conducted to explore the anti-inflammatory action of $2-hydroxyethyl-{\beta}-undecenate$ (HPS) purified from Cumin (Cuminum cymium L.) seed against periodontitis. From the study in which human leukocyte was employed to detect the inhibiting effects of 5-lipokygenase and cyclooxygenase, enzymes generating carriers of infection like $LTB_4$ and PGs, as well as of collagenase and elastase, organ-destroying enzymes, following conclusions could be drawn: HPS was found to inhibit leukotrien $B_4$ biosynthesis by stimulating more than 97% of human polymorphonuclear leukocyte (PMNL) with addition of $5\;{\times}\;10^{-2}\;M$ when $IC_{50}$ was set at $2\;{\times}\;10^{-4}\;M$. Ninety-two percent of enzyme activation turned out to be inhibited when $5\;{\times}\;10^{-2}\;M$ was added in a test to prove inhibiting effects of HPS against activation of PMNL 5-lipoxygenase from homogeneous humans and purified 5-lipoxygenase on the market. Besides, $IC_{50}$ for enzyme activation was valued at $2.5\;{\times}\;10^{-4}\;M$, while the value of $IC_{50}$ for purified 5-lipoxygenase was $2.3\;{\times}\;10^{-4}\;M$. The $IC_{50}$ values of COX-activated leukocyte and purified collagenase were $5.1\;{\times}\;10^{-4}\;M$ and $2.3\;{\times}\;10^{-4}\;M$, respectively. Moreover, the value of $IC_{50}$ for activation of leukocyte collagenase was $2\;{\times}\;10^{-3}\;M$, whereas that for purified collagenase was $5\;{\times}\;10^{-2}\;M$. In case of leukocyte elastase, addition of $5\;{\times}\;10^{-2}\;M$ inhibited its activation by 66%. In case of purified one, however, activation of enzyme was inhibited by 25% with addition of $5\;{\times}\;10^{-2}\;M$. Furthermore, the $IC_{50}$ value for activation of leukocyte elastase was revealed to be $7.5\;{\times}\;10^{-3}\;M$. From the virulence test with human gingiva cell, it was shown that, on the second day of cultivation, 47.83% of the cell had been activated when HPS was added by $5\;{\times}\;10^{-2}\;M$. Even the addition of HPS by $1\;{\times}\;10^{-2}\;M$ featured 68.53% of cell activation, suggesting relatively strong toxicity of the substance against gingiva cell.

Antimutagenic effects of extracts from curry powder and its individual fourteen kinds of spices, were investigated by Ames test. The antimutagenic effects against a direct mutagen, 2-nitrofluorene(2 -NF) and two indirect mutagens, 2-anthramine(2-AT) and 2-acetamidofluorene (2-AE) in the S. typhimurium TA98 were tested. For the 2-NF, the antimutagenicity of cinnamon, fenugreek, fennel, ginger, clove, turmeric and celery seed were determined as 42, 38, 32, 28, 24, 23 and 20%, respectively. The antimutagenicity of clove against the 2-AT was the highest (116%), and followed by the order of celery seed(103%), cardamon(100%), red pepper(99%), cinnamon(92%), cumin(83%), ginger(82%), fennel(82%), coriander (71%), nutmeg(68%) and turmeric (55%). The results also showed that the antimutagenic effect of clove against the 2-AF was superior to other spices. In case of curry powder among more than 10 kinds of spices, the antimutagenenicity against the 2-AT and 2-AF showed 23% and 6%, respectively, but no effect was observed against the 2-NF.

Objectives: Nigella sativa (black seed or black cumin), which belongs to the Ranunculacea family, is an annual herb with many pharmacological properties. Among its many active constituents, thymoquinone (TQ) is the most abundant constituent of the volatile oil of Nigella sativa (N. sativa) seeds, and it is the constituent to which most properties of this herb are attributed. Methods: PubMed-Medline, Scopus, and Web of Science databases were searched to identify randomized control trials (RCTs) investigating the therapeutic effects of N. sativa and/or TQ. In this review, we investigated the clinical uses of N. sativa and TQ in the prevention and the treatment of different diseases and morbidity conditions in humans. Results: Black seed and TQ are shown to possess multiple useful effects for the treatment of patients with several diseases, such as inflammatory and auto-immune disorders, as well as metabolic syndrome. Also, other advantages, including antimicrobial, anti-nociceptive and anti-epileptic properties, have been documented. The side effects of this herbal medicine appear not to be serious, so it can be applied in clinical trials because of its many advantages. Conclusion: Some effects of N. sativa, such as its hypoglycemic, hypolipidemic and bronchodilatory effects, have been sufficiently studied and are sufficiently understood to allow for the next phase of clinical trials or drug developments. However, most of its other effects and applications require further clinical and animal studies.

This study aimed to investigate the antioxidant ability of a cumin seeds ethanol extract (CE). The DPPH and ABTS radical scavenging activities of 0.25, 0.5, and 1.0 mg/mL of CE were found to be 24.6, 41.4, and 73.4 and 14.5, 27.2, and 50.1%, respectively (p<0.05), suggesting a dose-dependent effect. Moreover, the total phenolic content of CE was $61.0{\mu}M$ tannic acid equivalent/g extract and the FRAP value was $429{\mu}M$ ascorbic acid equivalent/g extract. In 9 hours of oil oxidation, CDA and ${\rho}-AV$ was significantly reduced to 13.4 and 59.1%, respectively, at a CE concentration of 100 ppm compared with that in the control (p<0.05). Major volatile compounds of CE were found to be ${\alpha}$-pinene, 2-butenal, cyclohexene, ${\beta}$-pinene, cis-sabinene, ${\rho}$-cymene, and limonene. These results suggest that CE containing volatile compounds has excellent antioxidant ability and oxidation stability, and thus could be used as a natural antioxidant to prevent oxidation in lipid foods.
