춘란(Cymbidium goeringii)에서 비슷한 지역에서 채취되고 유사한 표현형을 보이는 품종들을 서로 자매품종들로 흔히 불린다. 그런데, 자매품종들의 원 채집지나 채집자에 대한 정확하지 않은 경우가 많고, 서로 간의 유전적 근연성을 밝힌 연구는 없었다. 본 연구는 자매품종들 간의 유전적 근친성에 대해 처음으로 조사하였다. 4 자매품종 그룹의 13 품종(358 시료)을 수집한 후 12 SSR의 유전자형을 multiplex PCR 방법으로 분석하여, 13 가지 복합유전자형을 분리하였다. 각 그룹에서 유래된 복합유전자형들의 계통도 분석과 형매 확률은 각 그룹을 구성하는 품종들이 서로 가까운 친척일 가능성을 시사하였다. 복합유전자형들은 품종-특이적인 경우도 있었지만, 일부는 그룹 내 여러 품종에서 동시에 관찰되었기 때문에, 자매 그룹내 품종들의 새로운 분류 기준의 확립이 요구되었다. 특히, 유사한 꽃의 특징을 보이면서 유전적 식별이 어려운 ‘홍노을’과 ‘루비’ 및 ‘노을’과 ‘세홍소’는 세밀한 표현형과 유전자형의 병행 분석을 통한 품종 별 정확한 식별 기준의 확립 및 품종 분류의 재정립이 필요하다고 판단된다. 본 연구는 춘란의 자매품종들의 근친 정도를 처음 밝힌 연구로서, 자매품종들의 유전적 본질에 대한 이해도를 높이고, 자매품종 명명의 재정립에 유용한 유전적 식별 기준을 마련하는데 도움을 줄 수 있을 것이다. Cultivars collected from similar regions and exhibiting similar phenotypes to each other are commonly called sister cultivars in spring orchid (Cymbidium goeringii). However, no exact information is available for the original collection places and collectors of sister cultivars, and no study has revealed the degree of genetic relationship among them. This study was performed to determine genetic kinship among sister cultivars. Thirteen flower-variant types of cultivars consisting of four sister cultivar groups (358 samples) were collected, and then thirteen combined genotypes were identified by the determination of 12 SSR genotypes using the multiplex PCR. The phylogenetic analysis and the sibling probabilities of the combined genotypes suggested that the cultivars constituting each group were close relatives. Some combined genotypes were regarded to be a cultivar-specific, but others were observed simultaneously in two or more cultivars within a group. Therefore, it was suggested to establish a new classification criteria on the sister cultivars. This study particularly proposes to prepare a detailed evaluation criteria for cultivar pairs of ‘Hongnoeul’ and ‘Ruby’, and ‘Noeul’ and ‘Sehongso’ in group-1 through exact co-analysis of the phenotypes and genotypes. As the first study on the genetic kinship between sister cultivars, this study will help to understand the genetic nature of the sister cultivars, and to re-classify them.

This study was conducted to determine antioxidative activities and antioxidant compounds of�ﾠ�ﾠ commonly consumed herb plants in South Korea. These were evaluated for antioxidative activities by DPPH and ABTS radical scavenging activities, reducing power and inhibition of lipid peroxidation. To determine the antioxidant compounds in herb plants, the content of polyphenolics, flavonoids were measured by spectrophotometric methods and vitamin C, vitamin E, β-carotene analysis were carried out by HPLC. DPPH radical scavenging activity was the highest value of 0.19 mg Trolox eq/mg residue in oreg� ﾠ ano whereas ABTS radical scavenging activity was the highest value of 0.34 mg Trolox eq/mg residue �ﾠ in thyme. The reducing power and inhibition activity of lipid peroxidation were the highest value of 0.9 mg and 79.1% in rosemary. The highest polyphenolic and flavonoid contents were 165.8 mg GAE/g�ﾠ �ﾠ residue in oregano and 87.2 mg CE/g residue in spearmint. Vitamin C contents were in the range of 7.1 �ﾠ to 163.1 ug/100 g. α-Tocopherol was in the range of 6.2 to 30.6 mg/100 g. β-Carotene was in the range �ﾠ�ﾠ �ﾠ�ﾠ of 4.8 to 24.6 mg/100 g. These results indicate that herb plants may be useful as potential antioxidant �ﾠ�ﾠ sources for human antioxidant defense system.

품종 및 재배년도에 따른 고춧가루의 Capsaicinoid와 Ascorbic acid의 성분 분석
박영은, 전지영, 이경민, 이재민, 노승우, 이준수 忠北大學校 農業科學硏究所 2016 農業科學硏究 Vol.32 No.1
Pepper (Capsicum annuum L.) is an important part of daily diet in Korea as a seasoning.�ﾠ�ﾠ Major Capsicum cultivars included Capsicum annuum, Capsicum baccatum, Capsicum chinense, Capsicum frutescens and Capsicum pubesecens and among them, Capsicum annuum is cultivated most highly in Korea. In this study, the cultivar and year-to-year variation of capsaicinoids and ascorbic acid contents in peppers were analyzed. Capsaicin contents were in the range of 0.29 to 295.54 mg/100 g and dihydro�ﾠ�ﾠ capsaicin contents were 0.10 to 201.29 mg/100 g, respectively. Ascorbic acid contents were in the range �ﾠ�ﾠ of 25.56 to 1,026.82 mg/100 g. The differences in capsaicinoid and ascorbic acid contents were not sig�ﾠ�ﾠ nificantly different (p < 0.05). In addition, validation parameters were determined to ensure analytical methods' validity. Generally, the results of validation parameters were reliable and satisfactory. This study provides reliable capsaicinoid and ascorbic acid data for the nutritional information.
