Objectives: This study investigated the aconitine contents analysis of Buja extracts (raw material of Buja, hot water extract of Buja, and hot water extract of Sambu-tang) and the single oral dose toxicity of Sambu-tang-R in six-week-old Sprague-Dawley rats in order to compare the toxicity of Buja extracts.
Methods: Aconitine content analysis is that Buja extracts were hold purity test. To detect single oral dose toxicity, six-week-old Sprague-Dawley rats were divided into two groups, a normal control group and a sambutang-R (2,000 mg/kg) group. For 14 days of treatment, clinical signs, body weight, clinical chemistry, necropsy, and histopathology were examined.
Results: The aconitine contents of the Buja extracts were Buja-RH (0.1738%), Buja-RD (0.1746%), and Sambu-tang-R (0.0961%). There were no cases of death in either the control group or the experimental group. Nor was there any disorder to the clinical signs or any significant change in body weight in either group. There was no significant change of clinical chemistry or disorder of necropsy findings in either the control or the experimental group. And there was no difference in histopathological findings in comparing the control group with the experimental group.
Conclusions: These results suggest that the aconitine content of the hot water extract of Buja was similar to the raw material of Buja, but the hot water extract of Sambu-tang had greatly decreased aconitine content. These results also suggest that a single oral lethal dose of Sambu-tang-R for Sprague-Dawley rats exceeds 2,000 mg/kg for both female and male rats.
