Objectives : Natural products containing bioactive compounds with high antioxidant activity are potentially important sources that can contribute to the improvement of various diseases. Therefore, the aim of this study was to investigate phenolic compounds of Cinnamomum cassia (C. cassia) ethanolic extract (CCEE). And then we evaluated the antioxidant effect. Methods : We used liquid chromatography with tandem mass spectrometry (LC-MS/MS) to identify the compounds in CCEE. LC-MS/MS was performed in positive ion mode using Shimadzu, Nexera HPLC system and IDA TOF mass system. Solvent A was distilled water and solvent B was acetonitrile as mobile phase. The analysis was performed at a flow rate of 0.5 ml/min, column temperature of 35 ℃ and wavelength of 284 nm. The antioxidant effect of CCEE was analyzed using DPPH (2,2-diphenyl-2-picrylhydrazyl free radical) and ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)). In addition, total phenolics and total flavonoids contents were measured to determine antioxidant effects. Results : Analysis using LC-MS/MS identified four compounds: Coumarin, Trans-cinnamaldehyde, Trans-cinnamic acid, and 2-Methoxycinnamaldehyde. Free radicals decreased in a concentration-dependent manner starting from 10 ㎍/ml of CCEE, and decreased to a level similar to Ascorbic acid (AA) from a concentration of 60 ㎍/ml onwards. Conclusions : Based on the findings, CCEE exhibits strong antioxidant activity as evidenced by the presence of Coumarin, Trans-cinnamaldehyde, Trans-cinnamic acid, and 2-Methoxycinnamaldehyde. Consequently, this study suggests that CCEE can serve as an important source of natural antioxidants and can be efficiently used in the management of oxidative stress diseases.

This study was conducted to evaluate the rehabilitation measures and select appropriate tree species and rehabilitation methods for rehabilitating the rock desert areas in Guizhou, China. The study was carried out during the periods from 2003 to 2006 and results are as follows. Afforestation site is classified as a dolomite sandstone hilly country, a halfstony hilly country, a karst physiognomy, a rock desertification farmland and an latent rock desertification farmland by soil type and rock desertification status. Total afforestation area of Xuiwen is 1,300ha and afforestation area of a dolomite sandstone hilly country, a halfstony hilly country, a karst physiognomy, a rock desertification farmland and an latent rock desertification farmland are respectively 104.0ha (8.0%), 146.6ha (11.3%), 200.5ha (15.4%), 705.7ha (54.3%) and 143.2ha (11.0%). Planted tree species were selected by five site types. Robinia pseudoacacia, Chamaecyparis obtusa, Thuja orientalis, Cupressus duclouxiana and Juniperus chinensis L. var. chinensis were planted in a dolomite sandstone hilly country and Choerospondias axillaris and Robinia pseudoacacia were planted in a halfstony hilly country. Cupressus duclouxiana, Zanthoxylum bungeanum, Lonicera fulvotomentosa, Ilex kudincila, Quercus aliena, Quercus variabilis, Choerospondias axillaris, Koelreuteria bipinnata, Cryptomeria japonica, Cinnamomum camphora and Cinnamomum bodinieri were planted in a karst physiognomy. Cupressus duclouxiana, Toona sinensis, Robinia pseudoacacia, Lonicera fulvotomentosa, Eucommia ulmoides, Ilex kudincha. Zanthoxylum bungeanum and Magnolia officinalis were planted in a rock desertification farmland. Lonicera fulvotomentosa, Juglans sinensis, Pyrus pyrifolia, Choerospondias axillaris, Prunus salicina and Diospyros Kaki was planted in an latent rock desertification farm land. Robinia pseudoacacia showed high survival rate in 2004 and 2005, but Zanthoxylum bungeanum and Cinnamomum camphora showed slightly low survival rate in 2004. Survival rate of planting species in 2005 was over 80% because some species which showed low survival in 2004 were changed with other species and a proper afforestation method was applied. Growth rate of tree species was evaluated by height and diameter growth rate. Cupressus duclouxiana showed a highest height growth rate in 2004. Toona sil1ensis, Choerospondias axillaris, Koelreuteria bipinnata, and Cinnamomum camphora showed almost 100% height growth rate in 2005, although they showed a negative height growth rate in 2004. Robinia pseudoacacia showed a good growth rate in the rock desertification farmland and the halfstony hilly country so it could give a commercial benefit like honey as well as an afforestation effect.

본 연구는 내측반월판 절제와 전십자인대 단열로 유발된 랫드 골관절염 모델을 이용하여 계피 (Cinnamomum cassia Blume, 육계(肉桂)) 추출물의 연골손상 방지에 대한 효과를 평가하였다. 골관절염유발 랫드 48마리를 군당 8마리씩 6군으로 음성 대조군과 골관절염 대조군, 체중당 diclofenac 2 mg 투여군, 계피 추출물 25 mg과 50 mg, 100 mg 투여군으로 각각 분류하여 수술 1주 후부터 12주동안 투여하였다. 연골 소실과 관절의 불안정성은 계피 추출물과 diclofenac 투여군이 골관절염 대조군과 비교할 때 유의하게 감소하였다(p < 0.05). 병리조직학적 평가에서 연골의 퇴행은 계피 추출물 투여량에 따라 용량 의존적으로 개선됨이 확인되었다(p < 0.01). 계피 추출물 투여군에서 관절구조 퇴행성 변화의 감소와 Safranin-O 염색 정도의 용량 의존적인 증가를 보여 연골 퇴행이 억제됨을 확인하였다. Diclofenac이 골관절염 진행에 있어 활성화된 caspase-3와 절단된 poly(ADP-ribose) 중합효소에 유도된 세포자멸사 표지율 증가에 별 다른 영향을 주지 않았지만 계피 추출물 투여군에서는 이들 세포자멸 표지자에 대한 반응세포는 유의하게 감소되었다(p < 0.05). 그러나, diclofenac과 계피 추출물 투여군은 5-bromo-2-deoxyuridine의 섭취에는 영향을 주지 않았다. 이러한 결과에서 계피추출물이 항염활성과 항세포 자멸 활성을 통해 관절연골에 보호 효과가 있음을 보였다.
