The extracts were prepared using 95% ethanol, and their antioxidant activities were assessed in terms of IC50 and Trolox equivalents. The DPPH assay yielded IC&lt;sub&gt;50&lt;/sub&gt; values of 187.91±28.09 μg/ml, 85.93±10.91 μg/ml, and 71.31±11.29 μg/ml for the leaf, stem, and root extracts, respectively. Similarly, the ABTS assay showed IC50 values of 181.78±22.96 μg/ml for the leaf extract, 70.07±6.40 μg/ml for the stem extract, and 48.09±8.77 μg/ml for the root extract. In both assays, the root and stem extracts exhibited comparable antioxidant activity, whereas the leaf extract showed significantly lower activity (p &amp;lt; 0.05). The FRAP assay revealed no significant differences among the extracts, with Trolox equivalent values ranging from 190 to 211 mg TE/g extract. These findings suggest that the root and stem extracts possess strong antioxidant activity and may be used interchangeably in applications requiring such properties, whereas the leaf extract has comparatively lower potential. Further studies are recommended to explore the therapeutic properties and potential health benefits of these extracts.&lt;/p&gt;

Either or both of oxidized low density lipoprotein (oxLDL) and glucose were applied to induce oxidative stress condition in human umbilical vein cultured (HUVCs) to observe superoxide dismutase (SOD) activity, nitric oxide (NO) level and morphological changes. &lt;strong&gt;Results:&lt;/strong&gt; Total polyphenol and flavonoid were 51.04 &amp;plusmn; 0.91 mg GAE/g and 0.13 &amp;plusmn; 0.01 mg catechin/g of dried weight (DW), respectively. Free radical reduction efficiency of crude extract observed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay showed IC&lt;sub&gt;50&lt;/sub&gt; value of 329.6 &amp;mu;g of vitamin C equivalent/mg of extracts. Frap value was showed 428.54 &amp;plusmn; 15.32 mM FeII equivalent/g of DW. The result observing in HUVCs showed that comparing to the control, SOD activity, NO and MDA level were maintained in 0.05 mg/mL of &lt;em&gt;L. leucocephala &lt;/em&gt;treated group, but NO and MDA level were lowered when comparing with oxLDL and glucose-induced oxidative stress. No change was observed in 0.05 mg/mL of &lt;em&gt;L. leucocephala&lt;/em&gt; treated group, comparing with control group. &lt;strong&gt;Conclusion:&lt;/strong&gt; This study has been performed to exhibit the antioxidant activity of &lt;em&gt;L. leucocephala&lt;/em&gt; in endothelium functions and has been found to have an appropriate concentration at 0.05 mg/mL in reducing oxidative stress condition in impaired fasting blood glucose patients. Nevertheless, the optimal level for toxic activity in inhibition of cancer angiogenesis should be further investigated.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">148</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;&lt;strong&gt;Ratikorn Chatchanayuenyong&lt;sup&gt;1,2&lt;/sup&gt;*, Patcharawan Sujayanont&lt;sup&gt;1,2&lt;/sup&gt;, Auranut Vuttivirojana&lt;sup&gt;1&lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
