A 90-day oral toxicity study of glycolipids from Dacryopinax spathularia in Beagle dogs
2017
Abstract The subchronic toxicity of glycolipids from Dacryopinax spathularia (herein referred to as “AM-1”) was studied in male and female Beagle dogs administered AM-1 by oral capsule at doses of 150, 500 or 1000 mg/kg/day for 90 days. AM-1 was well tolerated at all dosages and there were no test article-related effects on survival, clinical observations, neurological screening (functional observational battery) parameters, clinical pathology parameters, organ weights, macroscopic or microscopic evaluations. Test article-related changes were limited to minimal effects on food consumption and body weight changes in the 1000 mg/kg/day group females. Therefore, the no-observed-adverse-effect level (NOAEL) was considered to be 1000 mg/kg/day, the highest dosage level tested. These results add to the safety database for these naturally derived jelly mushroom glycolipids with potential for use as a food ingredient.
