Dose response curve of NF-kB (a) and nitric oxide (b) synthesis for various extract/fractions of F. xanthoxyloides. FXM Fraxinus xanthoxyloides methanol extract of leaves, FXH Fraxinus xanthoxyloides n-hexane fraction of methanol extract of leaves, FXC Fraxinus xanthoxyloides chloroform fraction of methanol extract of leaves, FXE Fraxinus xanthoxyloides ethyl acetate fraction of methanol extract of leaves, FXB Fraxinus xanthoxyloides n-butanol fraction of methanol extract of leaves, FXA Fraxinus xanthoxyloides residual aqueous fraction of methanol extract of leaves. The values above ‘0’ point intersect indicate inhibition while below represent stimulation
