Abstract

Objectives: Despite the pharmacological potential of the roots and stems of hemp based on literatures, active research has not been conducted for a long time. Comparative experiments were conducted on antioxidant and anti-inflammatory effects and improvement of glucose uptake using Cannabis root and stem extracts. Methods: Antioxidant contents in Cannabis root and stem extracts were examined with total phenolic, tannin, flavonoid assay. Anti-inflammatory properties were tested in lipopolysaccharides-treated RAW264.7 cells. Efficacy of Cannabis root and stem extracts on glucose uptake was investigated using fluorescent glucose analog (2-NBDG) in palmitate-treated HepG2 cells. The mechanism of action on metabolism was examined by western blot. Results: Antioxidant and anti-inflammatory efficacy were greater in stem extracts, but improvements in glucose uptake performed under various conditions were found to be greater in root extracts. It is assumed that Cannabis root extracts exhibited an improvement in glucose uptake through mechanisms such as AMP-activated protein kinase activation, not depending on general antioxidant and anti-inflammatory effects. Conclusions: Further research is needed on the mechanisms and substances that exhibit the anti-diabetic effects of Cannabis roots and stems.
