Objective: Despite having numerous physiological benefits, toxicological assessment of green coffee beans is sparce. Here, we document the oral acute and sub-chronic toxicity of a standardized decaffeinated green coffee bean extract containing 50% chlorogenic acids (CGA-7™) in rats. Methods: We have performed a limit test at single oral dose of 2000 mg/kg to evaluate the acute toxicity in female Wistar rats. Furthermore, repeated dose 90-day toxicity study was conducted to assess the risk of long-term use of CGA-7. Result: A 14-day observation revealed no clinical signs of toxicity or mortality in animals at 2000 mg/kg acute oral dose of CGA-7. The administration of 250, 500, and 1000 mg/kg CGA-7 showed significant alterations in some parameters such as food consumption, relative organ weights of brain and spleen, haematological and biochemical parameters compared to control. These changes were not consistent and dose-dependent throughout the study. Furthermore, the changes were within the physiological range and toxicologically insignificant. CGA-7 did not affect the normal metabolism and physiology of the animals up to 1000 mg/kg dose. Macroscopic and histological examination of organs did not reveal any organ toxicity. Conclusion: Finally, the findings from this study suggest the safety of green coffee bean extract.

This study investigated whether decaffeinated green coffee bean extract prevents obesity and improves insulin resistance and elucidated its mechanism of action. Male C57BL/6N mice(N=48)were divided into six dietary groups: chow diet, HFD, HFD-supplemented with 0.1%, 0.3%, and 0.9% decaffeinated green coffee bean extract, and 0.15% 5-caffeoylquinic acid. Based on the reduction in HFD-induced body weight gain and increments in plasma lipids, glucose, and insulin levels, the minimum effective dose of green coffee bean extract appears to be 0.3%. Green coffee bean extract resulted in downregulation of genes involved in WNT10b- and galanin-mediated adipogenesis and TLR4-mediated proinflammatory pathway and stimulation of GLUT4 translocation to the plasma membrane in white adipose tissue. Taken together, decaffeinated green coffee bean extract appeared to reverse HFD-induced fat accumulation and insulin resistance by downregulating the genes involved in adipogenesis and inflammation in visceral adipose tissue.
