Biological Activities in the Leaf Extract of Lythrum salicaria L.

In this study, the bioactivities of ethanol (EELS) and water extract (WELS) from the leaf of Lythrum salicaria L. were investigated. In the anti-cancer activity, the growths of both human prostate cancer (DU145) and human colonic carcinoma cell (HT29) were inhibited up 60% by adding 10 mg/$m{\ell}$ of EELS. Anti-inflammatory activity of EELS and WELS have been evaluated on lipopolysaccharide (LPS) induced release of nitric oxide (NO) by the macrophage RAW 264.7 cells. EELS and WELS inhibited inflammatory by 57.3 and 46.9% in 10 mg/$m{\ell}$, respectively. In the anti-oxidative activity, $IC_{50}$ of DPPH radical scavenging activity was respectively 60.71 and $92.90\;{\mu}g/m{\ell}$ by EELS and WELS. In the anti-diabetic activity, $IC_{50}$ of ${\alpha}$-amylase inhibitory activity of EELS and WELS were respectively 5,250 and $5,020\;{\mu}g/m{\ell}$. $IC_{50}$ of ${\alpha}$-glucosidase inhibitory activity was 7.96 and $68.41\;{\mu}g/m{\ell}$ by EELS and WELS. In the anti-obesity, $IC_{50}$ of lipase inhibitory activity was 880 and $9,840\;{\mu}g/m{\ell}$ by EELS and WELS. Finally, EELS and WELS exhibited anti-oxidative, anti-inflammatory, anti-diabetic activity and anti-obesity. It suggests that Lythrum salicaria L. could be potentially used as a resource of bioactive materials for health functional foods.
