Neoandrographolide is one of the constituents in this plant. But there are no previous reports of isolation of neoandrographolide from &lt;em&gt;A. macrobotrys&lt;/em&gt;. Current work is undertaken to concentrate on isolation, characterization, and evaluation of tumor necrosis factor-alpha (TNF-α) inhibition activity of neoandrographolide from &lt;em&gt;A. macrobotrys&lt;/em&gt;. &lt;strong&gt;Materials and Methods: &lt;/strong&gt;For the isolation process techniques like column chromatography, thin-layer chromatography (TLC), and preparative TLC were used. Characterization was done by ultra visible (UV)-visible spectroscopy, Fourier transform infrared (FTIR), proton nuclear magnetic resonance (1H NMR), carbon-13 (C13) nuclear magnetic resonance (13C NMR) analysis. 3-(4,5-dimethylthiaxo-2yl) 2, 5-diphenyl tetrazolium bromide (MTT) assay was done for the preliminary cytotoxicity test to standardize the sample concentration for the TNF-α inhibition study. The flowcytometric method was used to determine TNF-α inhibiting ability in a human monocytes cell line (THP-1). &lt;strong&gt;Results:&amp;nbsp;&lt;/strong&gt;Neoandrographolide was isolated from methanolic extract of &lt;em&gt;A. macrobotrys&lt;/em&gt; which had a melting point of 174-175ºC. FTIR results had shown stretching for –OH, 3427.58 cm&lt;sup&gt;-1&lt;/sup&gt;,sp&lt;sup&gt;3&lt;/sup&gt;-CH, lactone, and α, β unsaturated ester. NMR data confirmed 26 carbon structures. Cytotoxicity of isolated neoandrographolide was 22.59 μg/ml. Further lipopolysaccharide (LPS) induced TNF-α inhibition was highest in the case of isolated neoandrographolide in comparison with the crude extract of&lt;em&gt; A. macrobotrys&lt;/em&gt;.&amp;nbsp;&lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;A. macrobotrys&lt;/em&gt; can be used as a new source of neoandrographolide with anti-inflammatory abilities by inhibiting the TNF-α release in THP-1 cells.&lt;/p&gt;
