Screening-Based Optimization of a Herbal Mixture (JH01) with Robust Anti-Obesity Effects in High-Fat Diet-Induced Obesity

초록

Obesity is a complex metabolic disorder associated with dyslipidemia, insulin resistance, and hepatic steatosis. Given its multifactorial nature, multi-component therapeutic strategies have attracted increasing interest, particularly herbal formulations containing diverse bioactive compounds. This study investigated the anti-obesity and hepatoprotective effects of a mixed herbal extract, JH01, composed of Curcuma longa, Achyranthes bidentata, and Polygonum multiflorum, using a screening-based analytical approach combined with experimental validation. Individual herbal extracts and their mixture were screened at 100 and 500 mu g/mL in 3T3-L1 adipocytes. Based on superior anti-adipogenic efficacy, JH01 was selected for further study. Its effects were evaluated in vitro by Oil Red O staining and quantitative real-time PCR analysis of adipogenic genes, and in vivo using a high-fat diet (HFD)-induced obese mouse model, assessing body weight, serum lipid profiles, liver function markers, adipokine levels, and hepatic histology. JH01 showed markedly stronger inhibition of lipid accumulation than individual herbal components. JH01 significantly suppressed adipocyte differentiation and downregulated PPAR gamma, C/EBP alpha, and SREBP-1 expression in 3T3-L1 cells. Furthermore, JH01 modulated inflammatory cytokines and adipokine levels, as evidenced by reduced TNF-alpha, IL-6, and IL-1 beta levels and increased adiponectin levels. In HFD-fed mice, JH01 reduced body weight gain, serum triglyceride and total cholesterol levels, improved ALT and AST levels, decreased leptin concentrations, and attenuated hepatic steatosis. JH01 exerts potent anti-obesity and hepatoprotective effects through coordinated regulation of lipid metabolism and adipogenesis, supporting its potential as a multi-herbal therapeutic strategy for obesity-related metabolic disorders.
