This study was aimed to explore the lipid peroxidation inhibitory activity of polar extract of &lt;em&gt;M. parviflora&lt;/em&gt;.&lt;strong&gt; Methods:&lt;/strong&gt; The polar extract is the result of ethanol extract partition solved in acetone. The extract will keep polar components which are insoluble in acetone. Assayed methods applied are &amp;szlig;-carotene bleaching inhibition, thiobarbituric acid reactive substance (TBARS) measurement, and continuous monitoring of conjugated dienes formation in LDL. &lt;strong&gt;Results:&lt;/strong&gt; &lt;em&gt;M. parviflora&lt;/em&gt; extract inhibit &amp;szlig;-carotene/ linoleic acid oxidation, showed by IC&lt;sub&gt;50&lt;/sub&gt; value of 15.83 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml in 30th minute; but the potency will be reduced to IC&lt;sub&gt;50&lt;/sub&gt; value of 111.19 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml and 225.07 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml after the 60th and 120th minute of incubation. &lt;em&gt;M. parviflora&lt;/em&gt; extract inhibit MDA formation as for linoleic acid peroxidation product until the third day; at 20, 40, 60, 80 and 100 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml inhibit MDA formation as many as 29.16 &amp;plusmn; 2.41%, 4.24% &amp;plusmn; 43.27, 54.08 &amp;plusmn; 2.87%, 59.88 &amp;plusmn; 1.90%, and 69.75 &amp;plusmn; 2.32%, respectively. M. parviflora extract at 50 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml can inhibit LDL-oxidation induced by CuSO&lt;sub&gt;4&lt;/sub&gt;, performed by LDL-oxidation lag-time elongation until 70 minutes, similar ability was performed by epigallocathecin gallate at 5 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml. &lt;strong&gt;Conclusions:&lt;/strong&gt; &lt;em&gt;M. parviflora&lt;/em&gt; extract expressed relatively strong protection against lipid and LDL oxidation which can serve as the scientific basis of its development as a remedy for various diseases caused by lipid peroxidation.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">171</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mufidah Murdifin,&lt;sup&gt;1&lt;/sup&gt;* Ermina Pakki,&lt;sup&gt;1&lt;/sup&gt; Gemini Alam,&lt;sup&gt;1&lt;/sup&gt; Marianti A.
