Four known cardiotonic steroids were isolated from roots of Adonis amurensis Regel et Radde and identified as digitoxigenin, cymarin, K-strophanthin and convallatoxin by chromatography on Amberlite XAD-2 resin and silica gel, high performance liquid chromatography and gel chromatography on Sephadex LH-20. In order to clarify the structure-activity relationship, thirteen related compounds of digitoxigenin were tested for the inhibitory activities for $Na^+,\;K^+$-adenosine triphosphatase from guinea pig heart. The inhibitory activities of related compounds of digitoxigenin were dependent upon the dicarboxylic acid and amino acid components. The compound having both the arginine and suberic acid moiety showed the higher inhibitory activity. The sulfate and glucuronide of digitoxigenin exhibited much less potency than the parent genin.

The infraspecific taxa of Adonis amurensis Regel et Radde are currently known to include one subspecies (subsp. nanus Y. Lee), two varieties (var. ramosa Makino, and var. dissectipetalis Y. Lee) and two forms (for. argentatus Y. Lee, and for. viridescensicalyx Y. Lee). Among them, the remaining three taxa except for subsp. nanus and var. dissectipetalis are unified with A. amurensis. Therefore, we examined the morphological characteristics and geographical distribution of A. amurensis in effort to elucidate the taxonomic status of subsp. nanus and var. dissectipetalis. After the subsp. nanus samples had been transplanted from their type locality, i.e. highland at more than 1,000 m above sea level, to a lowland habitat, we measured the samples' morphological characteristics. The range of values we recorded of the plant height and floral diameter from the subsp. nanus samples were within the parameters used to characterize A. amurensis. Accordingly, subsp. nanus has been characterized as an ecophene of A. amurensis. It is considered as a synonym of A. amurensis. Among the populations of A. amurensis (sensu Y.Lee, author), those with highly dissected petals at their apices have previously been described as var. dissectipetalis. However, this characteristic has been observed together with obtuse or rounded petal apices not only in one population but also in a single individual. However, populations with these characteristics belong to A. pseudoamurensis due to the simultaneous development of leaves and flowers, branched stems, acute leaf apices, and petals that are shorter than sepals. Therefore, we suggest that A. amurensis var. dissectipetalis be unified with A. pseudoamurensis. Very useful characteristics for distinguishing A. amurensis from its relative species are anthesis, the presence or absence of branches, the development of scales into normal leaves, the relative length of the sepals and petals, and the position of the stipules. A. amurensis is geographically restricted to E. Asia, including E. Siberia, and especially on the Korean Peninsula, it is distributed throughout the northern provinces of Gyeonggi province and in Gangwon province, Gyeongbuk province (Mt. Bohyeon-san) and Jeonbuk province (Mt Jeoksang-san) along Baekdudaegan mountain.

The morphology of plants and scanning electro-microscopical features of fruits were examined to evaluate the taxonomic entities of Korean Adonis L. in sensu lato (Ranunculaceae). The species of Korean Adonis were readily diagnosed by the branching pattern of stem, the number of flowers, the bifurcation of leaf main axis, the number of tepals, the flowering periods in relation to leaf sprouting, and the number of stomata and the texture of fruit surface. This study demonstrates that there are three species, A. amurensis, A. pseudoamurensis, and A. multiflora., found in Korea. However, A. ramosa, which has been often claimed to be distributed in Korea, is not present in Korea.

본 연구는 남한에 자생하는 한국산 복수초를 원예용 경제작물로 개발하고자 수행하였다, 남한의 21개 자생지를 대상으로 분포지역에 따른 개체군의 형질특성을 조사하여 다음과 같이 식물체의개체군 특성에 의해 4가지 유형으로 구분되었다. 강원도의 백두대간을 중심으로 자생하는 복수초군은 개화시기가 가장 빠르고 초장은 15cm이하로 작았으며 꽃받침이 꽃잎에 비해 큰 것이 특징이다 . 화경은 2.73cm 로 다른 복수초들에 비해 소형이다. 중부지방의 광릉 등지에 자생하는 복수초군은 개화시기가 3월 15일경으로 상대적으로 개화시기가 늦다. 화경은 3.67cm로 나타났다. 충청도 및 서해안 등지에 자생하는 복수초군은 개화시기가 빠르고 화경이 6,82cm 로 꽃이 크며 초장이 길어 관상가치가 뛰어나므로 금후 원예금후 원예작물로 개발 가능성이 높다. 제주도에 자생하는 복소초군은 잎과 꽃이 동시에 발달하고 화색은 밝은 황색이며 엽색도 다른 복수초들에 비해 엷은 빛깔의 초록색으로 나타났다. 또한 우리나라에 자생하는 복수초의염색체는 자생지에 관계없이 2n=16으로 조사되었다.

Morphological characters of aggregated achenes, and achene and its epidermal microstructures were observed for 7 taxa belonging to the section Adonanthe of subgenus Adonanthe [A. amurensis Regel et Radde, A. bobroviana Sim., A. davidii Franch., A. multiflora Nishikawa et Ko. Ito, A. pseudoamurensis W. T. Wang, A. ramosa Franch. and A. tianschanica (Adolf) Lipsch. ex Bobrov] and for 1 taxon belonging to the section Lophocarpa of subgenus Adonis (A. aestivalis var. parviflora M. Bieb.). The morphological characters such as shape of aggregated achenes, length of aggregated achenes, shape of achene, and recurved type of persistent style were useful in the classification of the subgenera Adonanthe and Adonis, and each species of the series under section Adonanthe. Epidermal microstructures of achene were grouped into three types according to the presence of microwrinkles and their arranged patterns. These microwrinkles were absent in A. amurensis, were of parallel type in A. bobroviana, A. pseudoamurensis, A. ramosa, and A. aestivalis var. parviflora, and were of parallelperpendicular mixed type in A. davidii, A. multiflora, and A. tianschanica. Also, a new key to them was made using morphological characters of their aggregated achenes and achene.

DNA sequences of nrITS regions obtained from 49 accessions representing 12 species and one variety within the section Adonanthe of the genus Adonis were analyzed to test the previous intra-sectional classification system and to determine their phylogenetic relationships. The results showed that the seven accessions of A. amurensis Regel et Radde included in the present study did not form a monophyletic group, as some of the accessions showed a close relationship with the Japanese endemic species A. ramosa Franch., which implies that the current species delimitation and identification of A. amurensis is problematic. Adonis pseudoamurensis W. T. Wang, which is frequently misidentified as A. ramosa in Korea, formed a segregated group, which suggests that they should not be considered as conspecific taxa. Accessions from A. shikokuensis Nishikawa et Koji Ito, A. multiflora Nishikawa et Koji Ito, and A. pseudoamurensis formed a clade, but monophyly of each species was not evident. The nrITS data did not support the classification system proposed by Wang, who classified sect. Adonanthe into four series, as most of these were found to be either polyphyletic or paraphyletic.
