Figure 4: Bar graph showing effect of various concentrations of P.betle leaf extract (A) on viability of LPS induced inflamed RAW 264.7 cell line. Viability of Control (untreated) is considered as 100%, +Dexa (Dexamethasone) is used as positive control and +LPS as negative control, to determine antiinflammatory property P.betle leaf extract of sample A by MTT assay.
