Preliminary investigations were carried out to isolate the constituents from the stems of genus Thalictrum. Methanol extracts of eight species from the genus were examined by thin layer chromatography. The author observed three different spots with Dragendorff's reagent in Thalictrum actaefolium, whereas none was detected in Thalictrum tuberiferum and Thalictrum simplex. Various fluorescent colors with different Rf values were detected in all species by UV ray, suggesting that each species may have different components.

Thalictrum species belongs to the Ranunculaceae and are perennial landscape plants which are available in the garden and potted plants. This experiment was conducted to find out the basic data for the growth effects of fertilizer levels and shading rate in seedling plug cell tray in the Thalictrum rochebrunianum, T. uchiyamai and T. coreanum. For T. rochebrunianum and T. uchiyamai, growth increased by all fertilizer level treatments as compared to non-treatment. Hyponex 1000 times of treatment showed the highest growth. All growth increased in 35% shading as compared to other treatments for T. rochebrunianum and T. coreanum. But, for T. uchiyamai growth increased in 55% shading. In general, growth of three Thalictrum species was worse in 75% shading, as compared to other shading rates. Based on the results, Thalictrum species seedling can be produced by 35-55% shading and fertilization of Hyponex 1000 times by using plug tray.

This study is about the five species of the genus Thalictrum growing abundantly in South Korea. Dried roots of plants; T. aquilegifolium var. japonica, T. simplex var. affine, T. actaefolium, T. tuberiferum were compared by morphological observation and screening test on the ingredient extracted by methanol, ether etc.. The experiments by thin-layer chromatography was at tempted to find out the similarity and the difference among them. In conclusion, the author found that: 1) A special component similar to coumarin was found under UV-ray from T. actaefolium. 2) By thin-layer chromatography, they show the corresponding spot supposed to be that of berberine and magnoflorine according to the $T_{ABLE}\;IV$. Therefore it is worthwhile considering that Thalictrum species would be a substitution for Epimedium species used as a tonic. 3) Thalictrum species has resemblance of ingredient and chemotaxonomy gives more help to classify them than the morphology.

한국산 꿩의다리속(Thalictrum) 17분류군 63집단에 대한 화분형태 관찰과 외부형태 재검토를 통하여 분류군의 한계 설정과 분류군 간의 유연관계를 파악하였다. 화분을 광학 및 주사전자현미경으로 관찰한 결과, 화사가 곤봉-막대기 모양으로 윗부분이 약의 너비보다 넓어지고, 약이 원두 또는 요두인 Sects. Physocarpum, Erythrandra, Tripterium과는 대조적으로, 화사가 실모양으로 가늘거나 약의 너비보다 좁고, 약이 예두-첨두 또는 다소 원두인 Sects. Omalophysa, Camptonotum, Thalictrum은 공구간거리가 멀고, 세 발아구 사이에 있는 자상돌기수가 많고, 화분지름이 크고, 자상돌기 높이가 낮은 경향을 보였다. 본 연구는 한국산 꿩의다리속 분류군이 모두 Microgynes절에 포함되는 Lecoyer (1885)의 분류체계를 지지하고 있으나, 이를 6개 절로 나눈 Tamura (1992)의 분류체계는 지지하지 않고, 만약 나눈다면 Lecoyer (1885)가 지적한 수술 특정과 본 연구에서 조사한 화분형태에 따라 Claviformes와 Filiformes로 나눌 수 있음을 보여준다. 외부형태를 재검토한 결과 한반도에 분포하는 분류군은 자생여부를 파악하지 못한 큰산꿩의다리(T. filamentosum)를 포함하여 총 17분류군(16종)이었고, 이들에 대한 검색표를 작성하고 분류학적 처리를 하였다.

Korean folk medicine 'Ggeong Yi Da Ri' has been used mainly as remedies for stomach trouble, bruise and neuralgia. The botanical origin of the crude drug has not been studied pharmacognostically. To clarify the botanical origin of 'Ggeong Yi Da Ri', the morphology and anatomy of leaf and stem were examined for the Korean species of Thalictrum plants, such as T. acetaefolium, T. aquilegifolium, T. filamentosum, T. minus var. hypoleucum, T. minus var. stipellatum and T. rochebrunianum. The botanical origin of 'Ggeong Yi Da Ri' was clarified as the leaf and stem from Thalictrum aquilegifolium and T. filamentosum.

To explore the biological activities of Thalictrum alkaloids, a study was initiated to investigate the alkaloidal constituents from T. fauriei, a species indigenous to Taiwan. Extensive fractionation of the ethanolic extract provided three known aporphines, (+)-oconovine (Ia), (+)-isocorydine (Ib), and (+)-corydine (Ic) from nonphenolic tertiary base fraction. From quaternary base fraction two new protoberberinium salts, thalifaurine (IIa), dehydrodiscretine (IIb), in addition to magnoflorine (III), were isolated. The structure of both new compounds were confirmed by total syntheses. Fractionation of phenolic bases yielded a dihydromorphinandienone, (-)-ocobotrine (IV), as well as a novel aporphine-pavine dimer, tentatively named EP-10. The structure of EP-10 was established by means of 2D NMR studies. Preliminary study indicated a weak activity of lyzing Hela cells, in vitro, for EP-10.

The habitats of specific plants were 40 sites including Berchemia berchemiaefolia of 11 sites, Hylotelephium ussuriense of 8 sites, Lilium cernuum and Thalictrum coreanum of each 3 sites, Exochorda serratifolia of 2 sites, and Lilium distichum, Aristolochia contorta, Jeffersonia dubia, Eleutherococcus senticosus, Salix chaenomeloids, Eranthis stellata, Scopolia japonica and Paeonia japonica of each 1 site. The altitude was the most in 300~400 m. In direction, NW was the most, and it showed SW in that order. The slope angle was the most in 0~10%, and the cliff showed in that order. In the results of species composition by stratum layer, Berchemia berchemiaefolia had the most, 15 species, in tree layer. In shrub and herb layer, this had the most as 20 species and 29 species, too. The species that occupied the largest size was Salix chaenomeloids in 2,500 $m^2$, and Jeffersonia dubia showed 1,500 $m^2$ in that order. The conservation of specific plants is to accomplish the ex situ and in situ conservation at the same time.

This study was carried out to develop an effective seed propagation method for Thalictrum rochebrunianum var. grandisepalum (H. Lev.) Nakai by analyzing seed dormancy types and germination characteristics. Seeds were collected between September to October at Gangwon province, and well-selected seeds were used while being dry-stored at 4±1℃. The seed size ranged 4.52 × 1.58 ㎜ and the weight of thousand seeds were 1,603.5 ± 0.02 ㎎. The moisture content was 7.2%. Seeds were achene type, and morphology characters showed an elliptical shape and rough texture, and light brown in color. Moist-chilling treatment was conducted for dormancy breaking because the seeds had an undeveloped embryo of liner type. The embryo had developed during a moist-chilling period, constantly, and fully developed in 10 weeks. Consequently, it seemed to be non-deep complex or intermediate complex type of morphophysiological dormancy, and embryo dormancy was broken by wet-chilling for 10 weeks. After 10 weeks of wet-chilling treatment, seed germination began. Germination percentage was higher in dark condition raher than light condition and recorded the maximum at 25℃ in the dark (16.3%). A pre-soaking treatment with a combined plant growth hormones promoted germination and shortened T₅₀. Specifically, seed germination of 84.5% was achieved by pre-soaking of seeds with a combined solution of 500 ㎎/L GA₃ and 10 ㎎/L kinetin for 24 h after a wet-chilling treatment for 10 weeks. Thus the effect of plant growth hormones coupled with chilling temperature on seed breaking dormancy provide asubsequent growth of seedlings for successful plantation.
