Evaluation of genetic toxicity, acute and sub-chronic oral toxicity and systemic safety of Agrimonia pilosa and Rhus gall 50% ethanolic extract mixture (APRG64) in vitro and in vivo (rodent and non-rodent animal models)

초록

Agrimonia pilosa (AP) and Rhus gall (RG) are traditional medicinal plants. The bioflavonoid composition standardized by HPLC analysis was named APRG64. Despite many studies reported to beneficial bioactivities of AP and RG, very limited range of toxicity tests have documented. So, we did experiment diversely on the toxicity tests of the substance APRG64. Genotoxicity (mammalian chromosomal aberration test, micronoucleus test) against APRG64, acute and sub-chronic toxicity test from rodent/non-rodent, and systemic safety pharmacology test were conducted. As a result of the test, genotoxicity against APRG64 was not observed. The NOAEL of rodents was confirmed as 2000 mg/kg/day and non-rodents was confirmed as 500 mg/kg/day. In addition, systemic safety pharmacological toxicity (effects on respiratory system, central nervous system, cardiovascular system) following administration of APRG64 was not observed. Finally, we accomplished ten potential toxicity tests and evaluated extensive safety of APRG64. Consequently, APRG64 may be a promising material for nutraceuticals and natural medicines.
