A Method for Zanba-Stir-Fried Tiebangchui Process Optimization

The dried root of Aconitum pendulum Busch and A. flavum Hand.-Mazz., one of the most famous Tibetan medicines, is called Tiebangchui (TBC) in Chinese1,2. The dried roots of TBC are helpful in dispelling cold and wind, reducing pain, and calming shock. It was recorded in the first volume of "Drug Standards (Tibetan Medicine) of the Ministry of Health of the People's Republic of China," which states that the dried roots of TBC are commonly used to treat rheumatoid arthritis, bruises, and other cold diseases3. However, the clinical therapeutic dose of TBC is similar to its toxic dose, and incidents of poisoning or death have been frequently reported due to improper use4. Therefore, reducing the toxicity and preserving the efficacy of TBC has become a research hot spot over the years.
In Tibetan medicine, processing is one of the most effective methods to attenuate the toxicity of TBC. According to "Processing specification of Tibetan medicine of Qinghai Province (2010)", the original herbs (TBC) should be placed in an iron pot and stir-fried with Zanba until the Zanba turns yellow, after which Zanba is removed and the herbs are dried in air5,6. However, no specific process parameters have been documented, which makes controlling the processing technology and the quality of Zanba-stir-fried TBC difficult. The CRITIC method is an objective weight method that can avoid fuzzification and subjectivity, and enhance the objectivity of weighing7. The Box-Behnken response surface method can directly reflect the interaction between each factor through polynomial fitting8. The combination of the Box-Behnken response surface and CRITIC method is commonly used to optimize processing technology to acquire the optimized processing protocol9,10. In this paper, a monoester-diterpenoid alkaloid (MDA) (benzoylaconitine) and two diester-diterpenoid alkaloids (DDAs) (aconitine, 3-deoxyaconitine) were used as evaluation indexes. CRITIC combined with the Box-Behnken response surface method was applied to optimize the processing technology of Zanba-stir-fried TBC and establish a standard processing method for clinical safe use.

Video: Response Surface Methodology (RSM) for Processing Technology Optimization of Zanba-Stir-Fried Tiebangchui (TBC)  

The dried root of Aconitum pendulum Busch., called Tiebangchui (TBC) in Chinese, is one of the most famous Tibetan medicines. It is a widely used herb in northwest China. However, many cases of poisoning have occurred because of TBC's intense toxicity and because its therapeutic and toxic doses are similar. Therefore, finding a safe and effective method to reduce its toxicity is an urgent task. A search through the Tibetan medicine classics shows that the processing method of TBC stir-fried with Zanba was recorded in the "Processing specification of Tibetan medicine of Qinghai Province (2010)". However, the specific processing parameters are not yet clear. Thus, this study aims to optimize and standardize the processing technology of Zanba-stir-fried TBC.
First, a single-factor experiment was conducted on four factors: the slice thickness of TBC, amount of Zanba, processing temperature, and time. With monoester and diester alkaloid contents in Zanba-stir-fried TBC as indexes, CRITIC combined with the Box-Behnken response surface method was used to optimize the processing technology of Zanba-stir-fried TBC. The optimized processing conditions of Zanba-stir-fried TBC were a TBC slice thickness of 2 cm, three times more Zanba than TBC, a processing temperature of 125 &#176;C, and 60 min of stir-frying. This study determined the optimized and standard processing conditions for the usage of Zanba-stir-fried TBC, thus providing an experimental basis for the safe clinical use and industrial production of Zanba-stir-fried TBC.

The present protocol describes an efficient and standard detoxification processing method for Zanba-stir-fried Tiebangchui using CRITIC combined with the Box-Behnken response surface method.
