Objective : In this study, we performed quantitative comparison on the content of 10 marker compounds in cinnamon barks from different species and found chemical discrimination between genuine Cinnamomum cassia and other Cinnamomum species (Non C. cassia). Methods : Cinnamon bark samples were extracted using the ultrasonication in 100% methanol for 30 minutes. The samples were analysed using high-performance liquid chromatography with statistical analysis. Results : The analytical method developed in this study met all validation criteria and was applied to the quantification of the 10 marker compounds in cinnamon bark samples. The major chemical discrimination of C. cassia were identified as low content of epicatechin and eugenol, and high contents of benzaldehyde, cinnamaldehyde and cinnamic acid compared to other Non C. cassia samples. Especially, among other compounds, the content of cinnamaldehyde was the highest in the C. cassia and Non C. cassia samples. The result of principal component analysis showed that the samples of C. cassia and Non C. cassia were clearly differentiated via benzaldehyde, cinnamaldehyde, cinnamic acid, eugenol, and epicatechin, which influenced on clustering C. cassia and Non C. cassia samples. Conclusion : C. cassia and Non C. cassia samples were chemically discriminated using the quantitative HPLC analysis. Based on this, it is possible to control the quality of herbal medicines containing Cinnamomi Cortex. It is necessary to further improve the accuracy of discrimination between C. cassia and Non C. cassia species to evaluate cinnamon bark quality.

Antioxidative and antimicrobial activities of essential oils of cassia (Cinnamomum cassia) and dill (Anethum graveolens L.) were investigated. Essential oils used in this study were added to soybean oil and stored at $65^{\circ}C$ for 9 days to examine their antioxidant activities using peroxide value (POV). The results showed that dill essential oil possessed a higher antioxidant activity than cassia essential oil. Strong antimicrobial activity was observed in cassia essential oil, whereas low activity was observed in dill essential oil against the test microorganisms. Heat stability and cell growth inhibitions were investigated with different concentrations of cassia oil. Results showed that cassia oil had thermal stability in a wide range of $70-160^{\circ}C$. Cassia inhibited cell growth of Bacillus cereus KCTC 1022, Micrococcus luteus A TCC 9341 and Escherichia coli ATCC 25922, but not great on Salmonella typhimurium ATCC 14028 at level of 200 ppm. In conclusion, the results indicate that dill essential oil could be a potential candidate for an antioxidative agent, while cassia essential oil could be suitable for use as an antimicrobial agent in the food industry.

This study was performed to evaluate the biological activity and protective effect of Cassia tora ethanol extracts against D-galactosamine induced hepatotoxicity in rats. Male Sprague-Dawley rats were grouped into normal group, D-galactosamine treated group(control), D-galactosamine plus 0.25% Cassia tora extracts treated group and D-galactosamine plus 0.5% Cassia tora extracts treated group. Normal and control group were fed control diet and Cassia tora extracts treated groups were fed experimental diets containing 0.25% or 0.5% Cassia tora ethanol extracts for 5 weeks. Body weight gain and liver weight of rats were not significantly different between groups. Cholesterol and triglyceride concentrations in serum and liver were significantly lower in rats treated only with D-galactosamine compared to normal group, and improved in Cassia tora extracts supplemented rats. D-galactosamine treatment significantly increased serum aspartate transaminase, alanine transaminase, gamma glutamyl transferase and alkaline phosphatase, however, the activities of aspartate transaminase and alanine transaminase were significantly decreased in Cassia tora extracts supplemented rats when compared with D-galactosamine treated control group. Cassia tora extracts significantly suppressed the D-galactosamine-induced elevation of liver thiobarbituric acid reactive substances(TBARS) contents. Superoxide dismutase activity was decreased by D-galactosamine treatment, however by the supplementation of Cassia tora ethanol extracts, significantly increased in dose-dependent manner. Glutathione peroxidase activity in rats fed diets containing Cassia tora extracts was decreased compared to control. Based on these results, we concluded that Cassia tora ethanol extracts may prevents the D-galactosamine-induced hepatotoxicity probably via an antioxidant mechanism.

결명자의 에탄올 추출물이 사염화탄소를 투여한 흰쥐의 간 손상에 미치는 영향을 알아보기 위하여 정상군, 사염화탄소 대조군, 결명자 에탄올 추출물 0.25%첨가군 및 0.5% 첨가군으로 나누어 5주간 사육한 후 혈청중 간기능관련 효소의 활성변화, 혈청 및 간장의 지질 및 지질과산화물의 함량, 간조직중의 catalase, superoxide dismutase, glutathione peroxidase의 활성변화를 관찰하였다. 체중증가량 및 식이섭취량은 각군간 유의적 차이가 없었고, 간중량은 정상군에 비해 사염화탄소 처리군에서 증가하였으며, 혈청지질함량및 간조직중의 지질함량에는 각군간 유의차가 없었다. 사염화탄소 대조군의 AST, ALT활성은 정상군에 비하여 2배이상 유의하게 증가하였으나 결명자 에탄올 추출물 처리군은 대조군에 비하여 유의하게 감소하였으며 추출물의 첨가농도가 증가할수록 더 많이 감소하였다. ALP, ${\gamma}-GTP$의 활성도 같은 경향을 나타내었으며, TBARS함량도 대조군에 비하여 결명자 에탄올 추출물투여군이 유의하게 낮아졌다. 간조직중의 catalase활성은 사염화탄소투여에 의해 유의하게 활성이 감소되었다가 추출물투여군에서 증가하는 경향을 나타내었으며 SOD활성에는 유의차가 없었다. GHS-Px활성은 사염화탄소 투여에 의해 높아진 대조군의 효소활성이 추출물투여군에서 유의하게 낮아짐을 볼 수 있었으며 추출물의 농도가 높을수록 더 많이 감소하였다. 이상의 실험결과 사염화탄소의 투여로 인해 높아진 혈청중의 간기능 관련 각종 효소 및 지질좌산화물의 함량이 결명자 에탄올 추출물을 투여함으로써 감소되었으며 추출물의 첨가농도가 증가함에 따라 그 효과가 뚜렷한 것으로 보아 결명자 에탄올 추출물이 흰쥐에 있어서 사염화탄소 처리로 인한 간 손상을 감소시키는 효과가 있는 것으로 판단되었다.
