Aconites distribute widely in northern hemispere of the earth reaching to arctic zone from warm and temperate one. Hitherto, these tuberous roots, 'Cho O', have been known to be famous plant poisons and essential important drugs possessing many remedial effects in each region of the world, especially in Korea and China. In Korea, although these plants grow widely in whole districts, their classifications are quite obscure. Especially, Aconitum triphyllum $N_{AKAI}$ is distributed whole districts. To clarify the botanical origin of 'Cho O', we studied on the anatomical characteristics of Aconitum triphyllum $N_{AKAI}$ growing wild in Korea. As a result, the environmental varieties of A. triphyllum $N_{AKAI}$ were recognized.

Aconites distribute widely in northern hemispere of the earth reaching to arctic zone from warm and temperate one. Chinese crude drug 'Cho O'(草烏) has been used as a remedy for apoplexy, dyspepsia, neuralgia, chronic rheumatis etc. Though the botanical origin of the crude drug has been considered to be Aconitum species of Ranunculaceae, there has been no confirmation on it. To clarify the botanical origin of Cho O, the morphological and anatomical characteristics of the roots of Aconitum species growing in Korea, i.e. A. chiisanense, A. ciliare, A. jaluense, A. napiforme, A. proliferum, A. pseudoproliferum and A. triphyllum were studied. As the result, Cho O was proved to be the roots of Aconitum triphyllum, A. jaluense, A. chiisanense and A. napiforme.

Aconitum triphyllum Nakai, the Korean spontaneous perennial herb, is one of the most important materials of oriental drug Fu-zi(aconite) and has long been used as cardiotonic for arrhythmia, analgesic and antiinflammatory drug in oriental countries. Although the plant is widely used for the preparation of aconite, the composition and amount of the toxic aconitine type alkaloids have not studied so far. As the preliminary study for seasonal variation of major constituents in mother tuber and daughter tuber of the plant, the authors tried to elucidate phytochemical characteristics of $C_{19}-diterpenoid alkaloids by $^{13}C-NMR$ spectra and seasonal variation of the alkaloidal contents by high performance liquid chromatography.

In the present study, we have examined the crossability of four species in the A. jaluense complex to provide additional information on their delimitation and levels of differentiation. Crosses between diploid A. chiisanense and the tetraploid species including A. jaluense s. str., A. triphyllum, and A. pseudoproliferum yielded no fruit- or seed-set, indicating that the former species is reproductively completely isolated from the latter three species. In interspecific crosses between the tetraploid species, combinations involving A. jaluense s. str. resulted in much reduced fruit- and seed-set, indicating that A. jaluense s. str. is more or less reproductively isolated from the other tetraploid species. However, crossing data revealed the absence of reproductive isolation between A. triphyllum and A. pseudoproliferum These results strongly support the relationships that have been previously suggested for the A. jaluense complex on the basis of morphology, chromosome number, and flavonoid chemistry.

Objective: This study was performed to analyze the single-dose toxicity of Aconitum kusnezoffii Reichb. pharmacopuncture (AKRP). Methods: All experiments were conducted at the Korea Testing & Research Institute (KTRI), an institute authorized to perform non-clinical studies, under the regulations of Good Laboratory Practice (GLP). Twenty (20) Sprague-Dawley rats were chosen for the pilot study. The animals were divided into four groups of five animals per group: group 1 (G1) being the control group with each animal receiving an injection of 0.3 ml of saline and groups 2, 3, and 4 (G2, G3, and G4) being the experimental groups with each animal receiving an injection of 0.1, 0.2 or 0.3 ml of AKRP, respectively. This study was conducted with the approval of the Institutional Animal Ethics Committee. Results: No deaths occurred in any of the 4 groups, and the $LD_{50}$ of AKRP administered via IV was higher than 1.77 ml/kg. Some changes in the weights of the male rates were observed between the control group and the experimental groups, but no significant differences were noted in the weights of the female rats. To check for abnormalities in organs and tissues, we stained representative sections of each specified organ with Hematoxylin & Eosin for light microscopic examination. The results showed no significant differences in any of the organs or tissues. Conclusions: The above findings suggest that Aconitum kusnezoffii Reichb. pharmacopuncture is a relatively safe treatment. Further studies on the subject should be conducted to yield more concrete evidence.

Aconiti Kusnezoffii Tuber has been traditionally used to treat the symptoms of rheumatoid arthritis and joint pain. The main constituents are diterpenoid alkaloids such as benzoylmesaconine, benzoylaconine, mesaconitine, aconitine, and hypaconitine. In Korea, Aconiti Kusnezoffii Tuber is officially defined as the tubers of Aconitum kusnezoffii Reichb., A. ciliare Decasisne, and A. triphyllum Nakai. On the other hand, only the tuber of A. kusnezoffii is to be used in China. In order to identify the botanical origin of Aconiti Kusnezoffii Tuber circulated in Korea, we analyzed 24 samples of Aconiti Kusnezoffii Tuber obtained from local markets for comparative DNA analysis. The sequence analysis of nrRNA ITS 1 was useful to distinguish Aconitum species and revealed that the roots of A. karakolicum were circulated in Korean markets without discretion. HPLC quantitative analysis showed that aconitine was detected at the highest amount in A. karakolicum. Authentic diterpenoid alkaloids were coinjected for quantification of aconitine-type ingredients. All data were statistically grouped by Principal Component Analysis (PCA). This study suggests that both molecular and chemical analyses should be utilized for the standardization and the quality control for Aconiti Kusnezoffii Tuber.
