본 연구는 면마과 가는쇠고사리[A. aristata (G. Forst.) Tindale]의 각 생육단계에 적합한 기내 대량증식법을 구명하기 위해 수행되었다. 포자를 1 / 8 - 1배로 조절한 MS 배지와 Knop 배지에 파종한 결과, Knop 배지에서 최종 발아율이 87.1%로 가장 높았다. 또한 전엽체를 배지의 종류, sucrose와 활성탄의 농도, 질소급원의 농도 및 비율을 다르게 처리하여 8주간 배양하였다. 실험의 결과, 가는쇠고사리의 전엽체는 sucrose 3%의 MS배지에서 $NH_4Cl$과 $KNO_3$의 비율을 20 : 40mM로 하여 총 농도를 60mM로 조절한 배지에서 증식이 가장 왕성하였다. 토양 종류에 따른 포자체 형성을 관찰한 결과, 상토:펄라이트를 2 : 1(v/ v)로 혼용하였을 때, 단위면적 당 발생한 포자체의 수가 73.8개 / $7.5{\times}7.5cm$로 가장 많았다. 반면 피트모스를 단용 및 혼용처리한 조건에서는 전엽체 발달 및 포자체 형성이 억제되었다. 따라서 가는쇠고사리는 MS 배지에서 전엽체를 증식시킨 다음 상토 : 펄라이트(v / v = 2 : 1) 혼합토양에서 포자체 형성을 유도하는 것이 효과적인 증식법으로 생각된다.

Objectives : This study was aimed to developing Korean herbalogy of the plants belonging to Aspidiaceae in Korea. Methods : The herbological books and papers published at home and abroad were researched. The total list of Aspidiaceae was made and Medicinal plants in Aspidiaceae was classified. The medicinal properties, action and applications of medicinal plants were investigated. Results : 1. There are totaled to 17 genera and 130 species in Aspidiaceae in Korea and among them medicinal plants are 11 genera, 31 species, some 24% in total. 2. Athyrium genus is main kind enough that it has 32 species among 130 species in Aspidiaceae, and medicinal plants of Dryopteris is 4 species. 3. The rhizome is the main medicinal parts if medicinal plants in the Aspidiaceae, which is used in 24 species. 4. According to nature and flavor of medicinal plants in the Aspidiaceae, they were classified into cool 15 and cold 8 species ; bitter taste 19, and little bitter taste 15 in the order. 5. According to meridian propism of medicinal plants in the Aspidiaceae, they were classified into liver meridian 5 species, stomach meridian 3 species. 6. According to the properties and principal curative action, they were classified into drugs for clearing away heat 25 species, drugs for detoxification 22 species, drugs for promoting diuresis 16 species in the order. 7. The number of toxic species in the Aspidiaceae was examined to be 5 species. Conclusions : There are totaled to 17 genera and 130 species in Aspidiaceae in Korea and among them medicinal plants are 11 genera, 31 species, some 24% in total. They were classified into drugs for clearing away heat, drugs for detoxification, drugs for promoting diuresisr.

This study was performed to select adequate plant materials for developing a natural ${\alpha}$-glucosidase inhibitor by analyzing ${\alpha}$-glucosidase inhibition activity in fronds and rhizomes of three Dryopteridaceae species: Cyrtomium fortunei, Polystichum polyblepharum, and P. lepidocaulon. The highest ${\alpha}$-glucosidase inhibitor obtained from frond of P. lepidocaulon ($4.16{\mu}g{\cdot}mL^{-1}$), and rhizome of C. fortunei ($1.84{\mu}g{\cdot}mL^{-1}$), showed much higher inhibition activity than acarbose ($1413.70{\mu}g{\cdot}mL^{-1}$). The biomass required to inhibit ${\alpha}$-glucosidase by 50% was 0.04 ~ 0.35mg for frond and 0.03 ~ 0.10mg for rhizome, and P. lepidocaulon required the least amount of fronds and P. lepidocaulon the least rhizomes. In frond, ${\alpha}$-glucosidase inhibition activity was the highest in water fraction of C. fortunei ($20.2{\mu}g{\cdot}mL^{-1}$), and n-butanol fraction of P. lepidocaulon ($9.33{\mu}g{\cdot}mL^{-1}$) and P. polyblepharum ($5.10{\mu}g{\cdot}mL^{-1}$). In rhizome, it was the highest in n-butanol fractions of C. fortunei ($19.76{\mu}g{\cdot}mL^{-1}$) and P. polyblepharum ($4.47{\mu}g{\cdot}mL^{-1}$), and ethylacetate fraction of P. lepidocaulon ($5.46{\mu}g{\cdot}mL^{-1}$). The frond biomass required for 50% ${\alpha}$-glucosidase inhibition was the lowest in the water fraction of C. fortunei (1.43mg), and n-butanol fractions of P. lepidocaulon (1.10mg) and P. polyblepharum (0.66mg). The required biomass of rhizome was the lowest in the water fraction of C. fortunei (1.59mg), and n-hexane fractions of P. lepidocaulon (0.04mg) and P. polyblepharum (0.15mg). The result of this study suggested that the three Dryopteridaceae species had high ${\alpha}$-glucosidase inhibition activity with small biomass, which might have high value as materials for economical anti-diabetic medication.
