The citrus extract based ZnO NPs were characterized by UV-Vis and FTIR spectroscopy, microscopy (SEM and TEM), EDX and XRD analyses. They were screened against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide (NO) free radicals. Finally, their inhibitory effects against egg albumin denaturation (EAD) were determined spectrophotometrically. &lt;strong&gt;Results:&lt;/strong&gt; The six afforded biogenic NPs consistently exhibited FTIR vibrational band around 500 cm-1, which is characteristics of a metal oxide (Zn-O) band. They also showed UV-Vis absorption peaks at 387 and 415 nm, suggesting the formation of ZnO NPs. Nova mandarin peel (NMP) ZnO NPs exhibited the best DPPH and NO radical scavenging activities, with 50% inhibitory concentration (IC50) of 7.61±0.69 and 19.93±0.40 μg/mL, respectively. It also gave the best inhibition against EAD, with an IC50 of 14.80±1.29 μg/mL. Morphological assessment of NMP extract-based ZnO NPs revealed rod-shaped particles at 35-50 nm range. &lt;strong&gt;Conclusion: &lt;/strong&gt;It has been shown through this study that citrus extract based ZnO NPs, especially those prepared with NMP, may have the capacity to attenuate free radical release and inflammation in biological systems.&lt;/p&gt;

It is used as anti-arthritis and anti-rheumatoid agents in Indian folklore medicine. &lt;strong&gt;Objective:&lt;/strong&gt; The present study was aimed to investigate total phenolic contents and free radical scavenging activity of the extracts from &lt;em&gt;Guaiacum officinale&lt;/em&gt; L. (Zygophyllaceae). &lt;strong&gt;Methods:&lt;/strong&gt; The plant parts including bark, twig and leaf were extracted using different solvents (ethyl acetate, water and ethanol). Total phenolic contents were determined by Folin-Ciocalteu Colorimetry method while free radical scavenging activity of the extracts was investigated by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity assay. &lt;strong&gt;Results:&lt;/strong&gt; The results show that the highest total phenolic content is found in the ethyl acetate twig extracts (20.3&amp;plusmn;0.0031 &amp;mu;g GAE/1 &amp;mu;g extracts). The ethanolic twig extracts had the highest free radical scavenging activity with IC50 of 0.45&amp;plusmn;0.0188 mg/ml. &lt;strong&gt;Conclusion:&lt;/strong&gt; The extracts from &lt;em&gt;Guaiacum officinale&lt;/em&gt; L. exhibit good anti-oxidant activity and may be suitable for development as drugs and supplementary food.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">929</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Suthira Maneechai&lt;sup&gt;1&lt;/sup&gt; and Vachiraporn Pikulthong&lt;sup&gt;2*&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
