지난 1970년이래 헝가리자연사박물관의 북한지역 탐사를 통해 채집조사되어 보관된 표본을 대상으로 검경한 결과 북한산 잎말이나방과 12종이 추가로 분류 동정되어 보고한다. 이중 2종(Notocelia rosaecolana Doubleday, Rhopobota ustomaculana Curtis)은 북한지역에서는 처음으로 보고되는 북한미기록종이었다. 이외에 보고되는 10종은 주로 기존문헌에 목록에만 포함되어 있어 정확한 분포정보들이 없어왔던 종들로 금번연구를 통해 새로운 분포지가 기록되는 종들이다. 본 연구에서는 금번에 보고되는 2종의 북한미기록종과 새롭게 채집지가 확인된 10종의 목록을 정리하여 보고하며 각 종별로 채집지기록, 국내외 분포 및 기주식믈정보 등을 제시하였다.

This study was carried out to obtain the information on the antioxidant activity of Phyllanthus. We compared and analyzed three indigenous collections of Phyllanthus: species from Korea, Brazil and Paraguay. Total phenolic acid contents were 1.93±0.015 mg/mL in KCS (Korean Collection Species), 1.65±0.003 mg/mL in PCS (Paraguay Collection Species) and 1.49±0.003 mg/mL in BCS(Brazil Collection Species). In both DPPH radical scavenging activities and SOD-liked activities, KCS was the highest (67.25±0.03%, 78.38±1.17%). KCS were also the highest in hydroxyl radical scavenging activities (95.80±0.17%). It turned out that there was no meaningful difference between BCS (81.64±0.23%) and PCS (81.54±0.04%). As for hydrogen radical scavenging activities, there was no statistically meaningful difference between KCS (36.44±0.24%) and BCS (36.31±0.33%) and it was the lowest in PCS (33.72±0.15%). Our results showed that KCS excelled the others not only in antioxidant activity but also in other beneficial effects. This encouraging results may be potentially useful in developing Phyllanthus urinaria L. variety which contains lots of functional elements such as total phenolic acid.

A total of 162 accessions of Perilla germplasm collected from diverse habitats in South Korea. The oil content of the seeds varied from 19.8 to 49.6%, the average being 33.3%. Oil content showed wide ranges of variation. The fatty acid composition of the seed oil showed the following overall ranges: palmitic 4.5 to 8.1%, stearic 1.6 to 7.4%, oleic 13.4 to 23.6%, linoleic 9.5 to 19.5%, and linolenic acid 48.6 to 66.4%. No correlation was found between oil content and fatty acid composition. The results obtained in this study provide useful background information for developing new cultivars with a high oil content and different fatty acid. Several accessions could be used as parental lines in breeding programs aiming to increase perilla oil quantity and quality.

We described and illustrated a rare species in Korea, Hypoxis aurea Lour. (Hypoxidaceae) which was rediscovered about 70 years after its first collection from Jeju island in Korea. The members of the family Hypoxidaceae R. Br. are distinguished from the plants of Amaryllidaceae J. St-Hill. by having grass-like leaves, an invisible stem which is modified into a corm or a rhizome, trimerous, and radially symmetric flowers with an inferior ovary developing into a capsule on scapes. Hypoxis aurea Lour. is readily distinguishable from Curculigo orchinoides Gsertn. in Japan by beakless ovary and capsular fruit. The number of somatic chromosome is 2n=54.
