|
A screening of Nepalese wild herbs for their antioxidant and antiobesity activity was carried out. The herbs including Allium hyposistum, Crateva unilocularis, Dryoathyrium boryanum and Cuscuta reflexa are widely used traditionally for various medicinal purposes in Nepal. The ethyl acetate fraction of D. boryanum showed polyphenol content of 266 μgGAE/mg with potent antioxidative activity assessed by DPPH free radical scavenging activity and hydrogen peroxide scavenging activity. The EtOAC fraction of D. boryanum also inhibited the lipid formation with 35% at 100 μg/mL in 3T3-L1 cell model. Along with this, butanol fraction of C. reflexa also showed potent antioxidative activity and inhibition of 80% of lipid formation at the test concentration of 75 μg/mL in 3T3-L1 cell line. This showed that these plant extracts have potential of antioxidant and antiobesity activity.
