Objective To optimize the extraction process of the classical herbal formula Huanglian Jiedu Decoction (HJD, 黃連解毒湯) by orthogonal experimental design combined with analytic hierarchy process (AHP) and entropy weight method (EWM), and validate its anti-inflammatory effects through cellular assays, so as to provide a reference for the rational extraction of HJD. Methods The contents of representative components in HJD, including berberine, baicalin, geniposide, and chlorogenic acid, as well as the mass of the supernatant and precipitated dry extract rate, were used as indicators. Key extraction parameters, such as the amount of water added, extraction time, and number of extractions, were selected. An orthogonal experiment combined with AHP-EWM was used to determine the comprehensive weight coefficients for each indicator, and a total score was calculated. The correlation between the comprehensive score of the extraction process of HJD and its anti-inflammatory activity was explored using the LPS-induced BV2 microglial cell inflammation model, and the anti-inflammatory stability of the optimized extraction process was verified. Results The optimized extraction process for HJD was determined to be 10 times the amount of water, with an extraction time of 30 min and three extractions. Extraction processes with comprehensive scores of 7.67, 9.82, and 12.05 were used to prepare HJD, named H1, H2, and H3, respectively, for pharmacological validation. The results showed that, compared to the blank control group, LPS-induced BV2 cells secreted NO, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6). Compared to the LPS group, H1, H2, and H3 all reduced the levels of inflammatory cytokines. Furthermore, correlation analysis revealed that HJD with higher extraction process scores exhibited stronger anti-inflammatory effects. Anti-inflammatory activity was further validated for H3, and the results demonstrated that H3, at three doses (100, 200, 400 μg/mL), significantly reduced LPS-induced inflammatory cytokine levels, demonstrating a good dose-response relationship. Conclusion The extraction process of HJD optimized by the orthogonal experiment combined with AHP-EWM is accurate, reliable, stable, and feasible. The research results can provide reference for subsequent studies on development and application of HJD.
