Chemical constituent from the roots of Solanum melongena L. and their potential anti-inflammatory activity
Three new compounds (1–3), were isolated from the ethanol extract of the roots of Solanum melongena L., together with twenty-seven knowns (4–30). On basis of their 1 D and 2 D NMR data, the chemical structures of islated compounds were elucidated combined with HR-MS and the relative values in literatures. In addition, the isolations were evaluated for the potential anti-inflammatory activity, by virtue of RAW 264.7 cells model induced by lipopolysaccharide (LPS)in vitro inhibitory activities on nitric oxide (NO) production. Compounds 12 and 21 showed moderate inhibition of NO production with IC50 values of 32.8 and 20.2 μM, respectively.
