response surface methodology (rsm) for processing technology optimization of zanba-stir-fried tiebangchui (tbc)

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.

Optimization of Processing Technology for Tiebangchui with Zanba Based on CRITIC Combined with Box-Behnken Response Surface Method

The scope of this protocol lies in the proceeding of the Tibetan medicines. This staff aims to the optimize and standardize the processing technology of Zanba-stir-fried Tiebangchui. The combination of the Box-Behnken response surface and the CRITIC method is commonly used to optimize proceeding technology to acquire the optimized proceeding protocol.The optimized processing conditions of two centimeter Tiebangchui slice thickness three times more Zanba than Tiebangchui, a processing temperature of 125 degrees C and the 60 metres of stir-frying. By quantifying the specific processing parameters, this method will benefit the large-scale production and the quantity control of Zanba-stir-fried Tiebangchui. The standard Zanba-stir-fried processing technology of Tiebangchui can provide useful information and the guidance for the processing of other poisonous ethnical medicines.The optimized process is stable and feasible, laying a certain foundation for further investigation of Tiebangchui products and related Chinese medicine preparations. Our laboratory will pay more attention to cytochemical investigation to obtain the targeted quantity control compliance. In addition, the pharmacological comparison overall in Zanba-stir-fried Tiebangchui is unclear.Detoxification and evaluation of the efficacy, reservation effects in animal models will be the next objectives.

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

To perform the Box-Behnken in response surface design for optimization of Zanba-Stir-Fried Tiebangchui or TBC processing technology. Use the range of sliced thickness the amount of Zanba, the processing temperature and the processing time determined by preliminary experiments using single factor tests. On the homepage.Click on new design, and in the left panel of the design page, click on response surface. Then click Box-Behnken and set the parameters for the four factors in the table. Click on next, set the response names and click on finish.To generate the response surface design. Complete the experiment based on the 29 scenarios designed for the response surface, using high performance liquid chromatography or HPLC. Record the peak areas and determine the quality of the MDA and DDAs in the Zanba Stir-fried TBC test samples.Then input the comprehensive scores obtained via the critic method for the 29 trials into the computer and analyze it using the referenced software, to perform the statistical validation of the polynomial equations in the left navigation pane. Under analysis plus, click on R1 and then click on start analysis. In the configure window, click on ANOVA in the top menu and observe the results table displaying variance analysis.Next in the top menu, click on model graphs and then 3D surface to obtain the response surface plots reflecting the effects of processing parameters on the synthetic scores. Go to the left navigation pane and under optimization click on numerical to validate the response surface model in triplicate under the predicted optimum conditions. Then in the top menu, click on solutions observe the predicted optimal conditions to verify the stability of the processing technology.The response surfaces and contour plots demonstrated the changes in synthetic scores as a function of four variables, on the basis of the experimental results. The adjusted optimal processing conditions were a slice thickness of two centimeters, three times more Zanba than TBC, a processing temperature of 125 degrees Celsius and a processing time of 60 minutes. The reliability of the model was proven through three tests that were conducted according to the obtained processing parameters.
