  • Phylogenetic studies were conducted to evaluate the taxonomic relationships among 27 taxa, including 2 outgroups of Korean Campanulaceae, using PCR-RFLP analysis and ITS sequences. In the PCR-RFLP analysis, 15 restriction endonucleases produced 244 restriction sites and size variations from the chloroplast DNA, and 59 restriction sites (24%) showed polymorphism. The length of the ITS regions ranged from 588 bp to 797 bp. The sequence divergence including the outgroups is 0-39.36%. Phylogenetic analyses based on PCR-RFLP and ITS data suggest that Campanulaceae is monophyletic; Codonopsis and Platycodon forms an independent clade; the Peracarpa and Asyneuma clade is a sister to the Adenophora-Hanabusaya clade; Campanula is monophyletic; and Wahlenbergia basally branches within the ITS tree, whereas they are placed between Campanula and the Codonopsis-Platycodon clade in the PCR-RFLP tree; Hanabusaya is placed within the Adenophora clade; and Adenophora is paraphyletic and shows discordance to the infrageneric classifications based on morphological data. The present results show two data sets, largely congruent at the generic level, but their phylogenetic positions, in particular the Wahlenbergia and Hanabusaya and the infrageneric classifications in Adenophora, show some incongruence.

  • Phylogenetic studies were conducted to evaluate the taxonomic relationships among 28 taxa, including 2 outgroups of Korean Campanulaceae, using atpB, atpB-rbcL, atpF-H, matK, rbcL, rpl16, rpoC1 and trnL-F regions sequences in chloroplast DNA. The combined analyses of eight chloroplast DNA regions suggest that Codonopsis and Platycodon basally branches within the phylogenetic tree; Wahlenbergia distinguished an independent clade; Campanula forms a clade; Peracarpa and Asyneuma clade is a sister to the Adenophora-Hanabusaya clade; Hanabusaya is placed within the section Remotiflorae of Adenophora; Adenophora form a clade. Our present results support the generic level, although discordance remained at the infrageneric groups such as section and series based on morphological characteristics in the genus Adenophora.

  • The present study was carried out to identify traditional konwledges on Korean Campanulaceae plants and conduct a comprehensive review of them through analyzing phytochemistry and pharmacology of Korean Campanulaceae plants. According to the literature study, the ethnobotanical plants of Korean Campanulacae consisted of a total 18 taxa. Of them, 12 taxa including Platycodon grandiflorus, Adenophora triphylla var. japonica, Codonopsis lanceolata and others have been used as ethnomedicinal plants. These plants have been used for the treatment of 49 diseases such as cold, asthma and postnatal care. Phytochemical studies have identified the constituents present from Korean Campanulaceae (Adenophora, Codonopsis, Platycodon, Campanula and Asyneuma). A wide range of chemical compounds comprised 109 triterpenes, 8 sterols, 4 polyacetylenes, 21 alkaloids, 14 flavonoids, 14 phenolic acids, 11 phenolic glycosides, 8 phenylpropanoids and 22 other compounds. Pharmacological studies of these compounds have demonstrated immuno-stimulating, anti-inflammatory, anti-asthmatic, apophlegmatic and anti-allergic effects. They have also shown antioxidant, estrogenic, anti-diabetic, hepatoprotective, neuroprotective, antinociception and anti-tumor activities, as well as anti-obesity and cardiovascular effects. In light of traditional knowledge and phytochemical and pharmacological studies summarized, uses of Korean Campanulaceae based on traditional knowledge (for the treatment diseases and conditions of respiratory, pregnancy, childbirth, puerperium, genitourinary, circulatory, musculoskeletal and other systems) have been supported by phytochemical and pharmacological studies.

  • 섬초롱꽃은 울릉군에 한정적으로 분포하는 여러해살이풀이다. 산림청에서는 약관심종(LC) 등급의 희귀식물이자 특산식물로 분류하고 있으며, 꽃의 관상가치가 특히 높아 화단용 소재, 절화용, 화분재배 등으로 흔히 이용되고 있다. 따라서 본 연구는 섬초롱꽃의 대량증식 시, 중금속이 미칠 수 있는 영향에 대해 파악하고자 수행하였다. 실험에 사용한 중금속은 카드뮴(Cd), 철(Fe) 두 종류이며, 두 종류 모두 1% 한천(agar)배지에 10, 25, 50, 100, 200 mg/L 농도로 녹여 사용하였다. 발아율 및 유근 생장을 위해 종자 및 유묘를 치상 후, $25^{\circ}C$ 항온 생장상에서 발아율 및 유근 발달을 관찰하였다. 발아율 측정결과, 아무처리도하지 않은 1% 한천(agar) 배지에서 $62.7{\pm}7.4%$로 가장 높았고 중금속 농도가 높아질수록 감소하였다. 카드뮴(Cd) 처리구에서는 10, 25, 50, 100, 200 mg/L 농도에서 각각 $17.3{\pm}1.3$, $2.7{\pm}1.3$, $1.3{\pm}1.3$, 0, 0%로 나타났다. 한편, 철(Fe) 처리구에서는 10, 25, 50, 100, 200 mg/L 농도에서 각각 $46.7{\pm}4.8$, $24.0{\pm}2.3$, $36.0{\pm}6.9$, $20.0{\pm}2.3$, 0%로 나타났다. 유근의 평균 생장 길이(mm)는 아무처리도 하지 않은 1% 한천(agar) 배지에서 19.6 mm로 가장 높았고, 중금속 농도가 높아질수록 낮게 나타났다. 카드뮴(Cd) 처리구에서는 10, 25, 50, 100, 200 mg/L 농도에서 각각 4.6 mm, 1.9 mm, 0.7 mm, 0.9 mm, 0 mm 생장한 것으로 나타났다. 한편, 철(Fe) 처리구에서는 10, 25, 50, 100, 200 mg/L 농도에서 각각 15.9 mm, 8.6 mm, 8.1 mm, 0.9 mm, 0 mm 생장한 것으로 나타났다. 실험결과를 종합해 볼 때, 섬초롱꽃 종자 발아 및 유근 생장의 억제는 카드뮴(Cd) 처리구에서 높게 나타났고, 철(Fe) 처리구에서는 비교적 영향을 덜 미치는 것으로 나타났다. 특히 카드뮴은 10 mg/L 농도만 처리하더라도 약 3.6~4.2배의 발아율 생장율 감소가 나타나, 섬초롱꽃 대량증식 시, 치명적일 것으로 판단된다. 본 실험의 결과는 섬초롱꽃 종자를 이용한 대량증식 및 유묘재배에 있어, 토양을 선택하는데 중요한 기초자료로서 활용될 것으로 기대된다.

  • Microscopic structures of epidermis and palynology and isozyme analysis were examined to find out the intergeneric and interspecific relationships and consequently to confirm the position of Hanabusaya aiatica as an endemic genus among 4 genera and 9 species belonging to the Hanabusaya asiatica, Korean endemic, and its allied groups. In the examination of microscopic structures of epidermis, cell patterns of perianth and ultrastructure of seed coat were found to be useful characters for the identification of the 4 genera and 9 species. Palynological characters such as microscopic structure and overall morphology of pollen grains were, however, not enough to distinguish them because of the great variabilities in these traits. Isozyme analysis showed that H. asiatica was very closly related to Campanula punctata and C. takesimana, though there were variations among populations and collected areas in some classified groups, depending on classified groups. Based on these results, the position of H. asiatica as an endemic genus was well confirmed.
