Abstract

|
Sasa borealis has long been used in folk remedies and traditional Korean medicine for analgesic, sedative and anticarcinogenic purposes. To excavate novel natural compounds for treating obesity, we separated leaf and stem and fractionated. We screened phenolic contents, anti-oxidative and anti-inflammatory properties with the fractions. Dichloromethane (DCM) and ethyl acetate (EA) fraction from both leaf and stem exhibited high anti-oxidative properties demonstrated by DPPH, ABTS assay in accordance with their phenolic contents. In addition, DCM and EA fraction from leaf inhibited nitric oxide (NO) production as well as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in Raw 264.7 cell. Finally, DCM and EA fraction from both leaf and stem significantly inhibited 3T3-L1 preadipocyte differentiation and decreased intracellular lipid level. These results suggest that DCM and EA fraction from Sasa borealis may contain therapeutic agent for obesity by attenuating inflammation and oxidative stress.
