Determination of Aconitum alkaloids in processed Buza (Cho-0, Salted Buza, Moist-heating Buza, Limed Buza), which had been prepared from the raw tubers of Aconitum chiisanenseb(Ranunculaceae), was established using visible spectrophotometry and high-performance liquid chromatography (HPLC) method especially for Aconitine analysis. Aconitum alkloids were reacted with tetra- thiocy-anatocobalt[II] complex ion to form a stable ion pair. The reaction product was insoluble in water but freely soluble in several organic solvents. 1.2-Dichloroethane was the best extracting solvent among the examined solvents. Spectrophotometry of Aconitum alkaloids at nax. 625 was carried out. The HPLC method for aconitine was carried out using Radial PAK-CN column with gradient solvent system by solvent mixture of acetonitrile and phosphate buffer (pH 3.0) at 4$0^{\circ}C$ and 254 nm. Linear relationship was found between absorbance response and concentration of aconitine in range of 0.45 mM~0.9 mM ($r^2$=0.9949) by spectrophotometry and 0.3 mM~1.2mM($r^2$=0.9983) by HPLC method. These methods have been found to be suitable and reproducible for routine analysis of Aconitum alkaloids and its pharmaceutical preparations.

Purpose: Unrefined tablets prepared from Aconitum tubers are occasionally used in Korean folk medicine. This study defines the potential sources, clinical toxicology, and treatment of aconitine poisoning. Methods: A retrospective survey was conducted in 63 patients in the ED of a tertiary University Hospital with suspected toxicity from an unrefined tablet prepared from Aconitum tubers from 1999 to 2007. Results: A total of 63 cases enrolled included 26 men and 37 women, aged 30 to 86 years. Forty-eight patients ingested aconitine tablets as digestives, 26 tablets on average. After a latent period of 30 to 450 minutes, patients developed a combination of neurologic (87.3%), gastrointestinal (82.5%), cardiopulmonary (41.3%), and other (28.6%) features typical of aconitine poisoning. Initial ECG abnormalities revealed dysrhythmia (61.9%), conduction disturbance (42.9%), and abnormal waveforms (39.7%), with 28.6% of patients having normal ECGs. All patients received supportive treatment or close observation regardless of ingestion amounts. Patients with hypotension or ventricular arrhythmia were treated with inotropic agents or amiodarone. Conclusion: Toxicologic signs and symptoms can occur after the consumption of aconitine tablets, regardless of ingestion amount. The risk occurs because of inadequately processed aconitine roots. This study will provide important data for public education and distribution regulations for Aconitum sp. in Korea.

Higenamine is a cardiotonic constituent of Aconite root, one of the most important oriental traditional medicine. Since Aconite root contains toxic aconitine alkaloids, variously processed roots have been often used. Much works have been done with the chemical significances concerning with the toxic aconitine alkaloids during the processing periods. However, effects of processing on higenamine have not yet been previously studied. In this paper, the extract pattern and the amounts of higenamine extracted with water from unprocessed and processed Aconite roots were compared. R-(+)-isomer was the only higenamine enantiomer detected although racemic higenamine was reported to be separated from Aconitum spp. Sonication for 1 hour resulted in higher higenamine extraction $(12.3\;{\mu}g/g)$ than boiling water extraction for 3 hours $(6.7\;{\mu}g/g)$ of unprocessed Aconite root. Extraction of not only higenamine but also most of the other components of unprocessed Aconite roots were reduced with boiling in water. Similarly, reduced extraction was observed with extracts of all three processed Aconite roots (Kyung-Po-Aconite root, Dang-Po-Aconite root and Huk-Peon-Aconite root) by either sonicated extraction or boiling water extraction.

A processed Aconiti tuber (Korean name, Kyeong-Po Buja) was extracted with 80% aqueous EtOH, and the concentrated extract was partitioned with EtOAc and water ($H_2O$). From the EtOAc fraction, two flavonoids were isolated through repeated silica gel column chromatographies. From the result of physico-chemical data including NMR, mass spectrometry and IR, the chemical structures of the compounds were determined to be liquiritin (1) and liquiritigenin (2). This is the first study to isolate flavonoids (1) and (2) from the processed Aconiti tuber.

Aconiti Tuber is the root of Aconitum sp (Ranunclaceae) which has been considered as one of the most important medicinal plant having cordiotonic, diuretic and analgesic effect. On the other hand, it has been known that Aconiti Tuber contained toxic agent, aconitine alkaloids so that only processed Aconiti Tubers have been used as herbal drug traditionally. For the safety evaluation of processed Aconiti Tuber, quantitative determination of aconitine and acute, subacute toxicity test were performed on 5 commercial processed Aconiti Tubers. Arapid and precise method using HPLC has been developed for the separation and determination of aconitine. Samples were extracted with hydrochloric acid (pH3) and hot water decoction. In case of d-HCL extracts, the contents of aconitine were from 0.08 mg/g to trace. But in case of hot water decoction extracts, the contents of aconitine were not detected. For the investigation of Aconiti Tuber toxicity in rats, hot water decoction samples and methanol extracts were tested. 1) Acute toxicity test Hot water decoction sample and methanol extracts from Aconiti Tuber did not show any toxic effects in rats by an oral administration. $LD_50values of 2 extracts were above 10.0 g/kg. 2) Subacute toxicity study In the repeated administration study, hot water decoction samples were given orally to Sprague-Dawlay rats for 2 week at daily doses of 5.0 g/kg. The results are as follows; No toxic manifestation, body weight changes and lethality were observed during wxperimental period. There were no significant changes in serum enzyme activities such as GOT, GPT, LDH, ALP between treated and control groups. However CPK values were decreased in the Subuja-treated group. (P<0.01). In addition, no gross and microscopic changes were noted in Aconiti Tuber-treated groups.

From the tuberous root of Aconitum carmichaeli Debx.(Ranunculaceae), the main root is called as common monkhood mother root and the later root is called as the prepared aconite root. From the prepared aconite root. Looking at the processing method of the prepared aconite root, it is divided into Yeombuja (prepared aconite root processed in salt) and heuksoonpyeon (baekbupyeon) following the processing method after removing the soil and this is a way of processing the prepared aconite root without damage it. The recently produced raw prepared aconite root is easily damaged, thus it shall be preserved in salt to have the crystal shape on the surface of the prepared aconite root and store and transport in firmly solidified yeombuja condition. Therefore, yeombuja shall remove the salt before use and requires processing for use but heuksoonpyeon or baekbupyeon may use immediately. For the succession of the unique processing techniques of our ancestors, there has to be studies on the techniques. Prepared aconite root is generally used as holy medicines to cure the yang depletion syndrome, kidney-yang deficiency syndrome, and obstruction of qi in the chest syndrome. However, they are the substances with toxicity. It is contemplated that the contents of processing are broadly understood through the document on the processing method, and based on such foundation, the systematic set and proof on the documents are made along with the addition of the contemporary scientific theory and technology to develop the traditional processing technology to maximize the treatment effect and safety of prepared aconite root. In this study, the historic data and records on the processing method of latteral root of aconitum carmichaeli Debx will be rearranged to contribute to the standardization of medicinal herbs, maximization of efficacy and minimization of the side effects.
