  • Colon cancer is considered as the precarious forms of cancer in many developed countries, with few to no symptoms; the tumor is often diagnosed in the later stages of cancer. Monoterpenes are a major part of plant essential oils found largely in fruits, vegetables and herbs. The cellular and molecular activities show therapeutic progression that may reduce the risk of developing cancer by modulating the factors responsible for colon carcinogenesis. Colon cancer was induced with DMH with a dose of (20 mg/Kg/body weight) for 15 weeks by subcutaneous injection once in a week. Myrtenal treatment was started with (230 mg/Kg/body weight) by intragastric administration, one week prior to DMH induction and continued till the experimental period of 30 weeks. The Invivo results exhibit the elevated antioxidant and lipid peroxidation levels in DMH treated animals. The Histopathological analysis of colon tissues well supported the biochemical alterations and inevitably proves the protective role of Myrtenal. Treatment with myrtenal to cancer bearing animals resulted in a remarkable increase in the inherent antioxidants and excellent modulation in the morphological and physiological nature of the colon tissue. It is thus concluded that myrtenal exhibits excellent free radical scavenging activity and anticancer activity through the suppression of colon carcinoma in Wistar albino rats.

  • 국내에서 자생하고 있는 더위지기와 사철쑥의 정유성분 조성의 차이점을 비교하기 위하여 각 시료로부터 수증기증류에 의해 정유를 분리한 다음 GC-MS 분석결과 및 문헌에 보고된 각 성분의 retention index 비교에 의해 성분을 동정하였다. 국내의 2개 지역에서 수집한 더위지기에서 분리한 정유에서 60종의 성분을 동정하였으며, 그중 한 시료에서는 iso-pinocamphone(31.64%), 1,8-cineole(21.55%), ${\beta}-pinene$(4.46%), pinocarvone(3.72%), myrtenal(3.42%) 및 trans-pinocarvel(3.14%)이 주요 구성성분이었으나 다른 시료에서는 camphor(26.99%), 1,8-cineole(11.02%), ${\alpha}-terpineol$(7.63%), borneol(4.10%), camphene(3.97%) 및 artemisia ketone(3.84%)이 주요 구성성분이었다. 또한 2개 지역에서 수집한 사철쑥에서는 80종의 성분을 동정하였으며, 두 시료간에 구성성분이나 성분별 조성비율은 유사한 편이었으나 그 중에서도 capillene$(26.01{\sim}30.31%)$, ${\beta}-pinene(8.55{\sim}18.38%)$, ${\beta}-caryophyllene(8.80{\sim}13.70%)$, $cis,trans- {\alpha}-farnesene(2.10{\sim}7.38%)$, ${\beta}-himachalene(1.57{\sim}5.57%)$ 및 germacrene D$(2.27{\sim}5.46%)$가 주요 구성성분이었다. 더위지기와 사철쑥의 정유 성분 조성상의 뚜렷한 차이점으로서 더위지기의 정유에서는 사철쑥에서 검출되지 않은 iso-pinocamphone 또는 camphor, 1,8-cineole과 같은 monoterpenoid 화합물의 함유비율이 높은 반면 사철쑥에서는 더위지기에서 검출되지 않은 acetylene화합물인 capillene 이외에도 sesquiterpenoid 화합물의 함유비율이 높은 것이 특징이었다.

  • The in vitro antimicrobial and antioxidant activities of the essential oil and methanol extracts of Ledum palustre L. were investigated. Using GC-MS analysis, we identified 37 compounds in the essential oil, constituting 87.58% of the total oil. There are several monoterpenes, of which sabinene is the major compound ($16{\sim}17%$). There are several oxygenated monoterpenes of which terpinen-4-ol(7.6%) and myrtenal (3.5%) are the main constituents. $\beta$-Selinene, a-selinene, $\gamma$-elemene, a-caryophyllene are the main sesquiterpenes ($2{\sim}6%$ range). The oil strongly reduced the diphenylpicrylhydrazyl radical ($IC_{50}=1.56{\mu}g/mL$) formation and exhibited a hydroxyl radical scavenging effect in the $Fe^{3+}-EDTA-H_2O_2$ deoxyribose system ($IC_{50}=2.7{\mu}g/mL$), and also inhibited the nonenzymatic lipid peroxidation of rat liver homogenate ($IC_{50}=13.5{\mu}g/mL$). The polar phase of the extract showed antioxidant activity. The oil showed antimicrobial activity against Streptococcus pneumoniae, Clostridium perfringens, Candida albicans, Mycobacterium smegmatis, Acinetobacter lwoffii and Candida krusei while the water-insoluble parts of the methanolic extracts exhibited slight or no activity. This study confirms that the essential oil of Ledum palustre L. possesses antioxidant and low antimicrobial properties in vitro.

  • 본 연구는 국내산 침엽수로부터 천연 항균화합물 개발을 목표로 미송 및 편백으로부터 추출물을 확보하여 푸른곰팡이병의 원인균인 Trichoderma spp. 5종을 대상으로 항균활성을 테스트하고 GC/MS를 이용하여 항균화합물을 탐색하였다. 미송 추출물은 Trichoderma spp.에 대해 1,000 ppm에서 저해 활성을 나타냈으며, 4,000 pp에서는 T. viride>T. harzianum>T. aggressivum 순으로 70.1, 67.3, 64.7%의 높은 항균활성을 나타냈다. 편백 추출물도 1,000 ppm에서 항균활성을 나타냈고 4,000 ppm에서 T. viride>T. harzianum>T. aggressivum 순으로 63.2, 59.3, 59.1%의 높은 항균활성을 나타냈다. 그러나 1,000 ppm의 미송추출물과 1,000 ppm의 편백추출물을 각각 9:1, 8:2, 6:4, 2:8 (w/w) 비율의 혼합제제로 만들어 Trichoderma spp.에 처리하였을 때 미송추출물 1,000 ppm 및 편백추출물 1,000 ppm 각각의 단일추출물보다 낮은 항균활성을 나타냈다. Trichoderma spp. 5종에 대해 높은 항균활성을 나타내는 미송추출물에서는 2-Isopropoxy-ethylamine 46.5%, epifluorohydrin 8.6%, trans-2,3-Di-methyloxirane 7.6%, (IR)-(-)-Myrtenal 6.0%, 2-Methoxy-4-Vinylphenol 3.9%, benzaldehyde 2.8%가 함유되어 있었고, 편백추출물에서는 ${\alpha}$-Terpinenyl acetate 14.9%, Sabinene 10.9%, dl-Limonene 9.6%, ${\alpha}$-Terpinolene 7.5%, ${\alpha}$-Pinene 7.1%가 함유된 것이 확인되었다.
