Abstract

For the investigation of possibility as a useful functional material, different parts of Lythrum salicaria L. harvested at four growth stages were studied in the aspect of bleeding characteristics, chemical composition and in vitro activity. Weights (g/plant) of L. salicaria plant parts were high in order to stem > leaf > flower > root at the best growth time. Crude lipids (3.59~4.30%) and crude proteins (14.7~23.5%) of L. salicaria leaves were the highest among the other plant parts showed from 0.08~3.54%, and 4.0~21.9%, respectively. Free sugars (2.9~4.2%) and crude ash (11.9~14.8) of leaves also showed the highest value. Free radical scavenging activities of L. salicaria root on 2,2-diphenyl-1-picrylhydrazyl showed from $43.5\;{\mu}g/m{\ell}$ to $47.6\;{\mu}g/m{\ell}$ as $IC_{50}$ which were followed by those of flower, leaf, and stem. Root of L. salicaria tested at $100\;{\mu}g/m{\ell}$ also showed the most efficient inhibitory effect on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in murine macrophage RAW264.7 cells. Cell viability of the plant parts tested by 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyl tetrazoliumbromide (MTT) assay was high in order to flower, leaf, root, and stem. Total phenol content measured as tannic acid equivalent showed the highest value in flower. In conclusion, among the plant parts, especially leaf of L. salicaria, was rich in the chemical components, and showed efficient antioxidant/inhibitory activity on free radical and NO production, and was expected to be a functional material candidate.
