As a commonly used Tibetan medicine with toxic effects, the toxicity-attenuating effect of processing is extremely important for TBC&#39;s clinical application25. In this study, the processing technology of TBC processed with highland barley wine was optimized. By reviewing the main active ingredients and relating the pharmacological effects of TBC, we found that TBC alkaloids have anti-inflammatory and analgesic effects and can be used to treat rheumatoid arthritis. In this study, a moderate toxi...

Tiebangchui (TBC), the dried root of Aconitum pendulum Busch, is a well-known Tibetan medicine and was initially recorded in the classic Tibetan medical book &#34;Four Medical Tantra&#34;1,2. According to &#34;Drug Standards of the Ministry of Health of the People&#39;s Republic of China (Tibetan Medicine)&#34;, TBC is effective in expelling cold, relieving pain, dispelling wind, and calming shock, and is commonly used to treat rheumatoid arthritis in clinics3,4,5.
TBC mainly contains alkaloids, including highly toxic diester-diterpenoid alkaloids (DDAs), and the moderately toxic monoester-diterpenoid alkaloids (MDAs)6,7,8. These chemical components are active ingredients with medicinal effects but are toxic. One of the most famous active and toxic ingredients, aconitine, causes poisoning when it exceeds 1 mg9. Therefore, improper or excessive use of TBC might result in poisoning and even death, and the toxicity attenuation and efficacy reservation of TBC is crucial for its safe clinical application10,11.
Processing is an effective method for detoxifying TBC. According to ancient Tibetan medicine books, processing with highland barley wine is an efficient way to attenuate toxicity and preserve the efficacy of TBC. TBC is soaked in highland barley wine, stored for one night, dried, and added to medicines12. However, the specific processing technology and potential influencing factors are rarely reported, and the traditional processing process often relies on experience and lacks standardized methods. Hence, modern scientific and technological methods for optimizing and standardizing the processing process are needed.
The Box-Behnken design method is used in investigating interactions among different factors and their influence on comprehensive scoring through quadratic polynomial fitting. This design allows the intuitive observation of optimal conditions and has been widely used in the field of pharmacy13. For example, the Box-Behnken design method, based on the entropy method, successfully optimized the processing technology of stir-frying with vinegar of Curcuma Longa Radix14. In this study, the Box-Behnken response surface experimental design combined with the entropy method was used in optimizing the processing technology of TBC processed with highland barley wine. The optimized processing technology is expected to ensure quality control and safe clinical use.

optimization of processing of tiebangchui with highland barley wine based on the box-behnken design combined with the entropy method

The processing of toxic ethnomedicines is of great significance for their safe clinical application. Thus, the limitations of traditional processing should be addressed, and the processing method of ethnomedicines should be standardized using modern research methods. In this study, the processing technology of a commonly used Tibetan medicine Tiebangchui (TBC), the dried root of Aconitum pendulum&#160;Busch, processed with highland barley wine was optimized. Diester-diterpenoid alkaloid (DDA) (aconitine, 3-deoxyaconitine, 3-acetylaconitine) and monoester-diterpenoid alkaloid (MDA) (benzoylaconine) content were used as evaluation indicators, and the weight coefficient of each evaluation index was determined by the entropy method.
The single factor test and Box-Behnken design were used in investigating the influence of the ratio between highland barley wine and TBC, slice thickness of TBC, and processing time. Comprehensive scoring was performed according to the objective weight of each index determined by the entropy method. The optimal processing conditions of TBC with highland barley wine were as follows: the amount of highland barley wine is five times that of TBC, a soaking time of 24 h, and a TBC thickness of 1.5 cm. The results showed that the relative standard deviation between the verification test and predicted value was less than 2.55% and the optimized processing technology of TBC processed with highland barley wine is simple, feasible, and stable, and so can provide a reference for industrial production.

In this study, the precision, stability, repeatability, and sample recovery of TBC indicated that the method is feasible. The four index components in TBC had a good linear relationship within a specific concentration range. Typical chromatograms are shown in Figure 1. The precision test results (Table 8) showed that the relative standard deviation (RSD) of the peak areas were 2.56%, 1.49%, and 2.03% for benzoylaconine, aconitine, and 3-deoxyaconitine, respectively, and 0.21...
