An equal volume of Griess reagent (1% sulphanilamide and 0.1% N-(L-naphthyl)-ethylene diamine dihydrochloride, dissolved in 2.5% H3PO4) was mixed with culture supernatant and color development was measured at 550 nm using a micro plate reader. The amount of nitrite in the culture supernatant was calculated from a standard curve (0&amp;ndash;100 &amp;mu;M) of sodium nitrite freshly prepared in deionized water. Percentage of the NO inhibition was calculated by using nitrate level of IFN-&amp;gamma;/LPS-induced group as the control. &lt;strong&gt;Results:&lt;/strong&gt; Isolated compounds, tetraprenyltoluquinone, rubraxanthone and &amp;alpha;-mangostin from stem bark of &lt;em&gt;Garcinia cowa&lt;/em&gt; Roxb were evaluated for their anti-inflammatory activity. Only &amp;alpha;-mangostin exhibited strong anti-inflammatory activity with 83.42 % inhibition of NO and without inducing severe cytotoxicity at 50&lt;em&gt; &amp;mu;&lt;/em&gt;M. Rubraxanthone showed weak inhibition of NO with 23.86 % inhibition of NO while maintained 77.32 % of cell viability. TPTQ also showed the strong inhibition of NO with 80.98 % inhibition but unfortunately this compound also induced severe cytotoxicity with 39.62% viability. &lt;strong&gt;Conclusion:&lt;/strong&gt; &amp;alpha;-Mangostin exhibited strong anti-inflammatory activity without inducing severe cytotoxicity at 50 &lt;em&gt;&amp;mu;&lt;/em&gt;M. Rubraxanthone showed weak inhibition of NO while Tetraprenyltoluquinone also showed the strong inhibition of NO however this compound also induced severe cytotoxicity.&lt;/p&gt;
