The BC-ZnONPs were characterized by microscopy (FESEM and HRTEM) and spectroscopy (UV-Vis and EDX) methods. &lt;em&gt;In vitro &lt;/em&gt;anti-hyperglycaemic evaluation was based on α-amylase and α-glucosidase inhibition assays. &lt;strong&gt;Results:&lt;/strong&gt; The BC-ZnONPs showed a spherical-to-cubical shape with a 10-50 nm size range. The UV-Vis absorption peaks at 387 and 415 nm suggest the formation of biogenic ZnO NPs. The EDX spectrum revealed 68.92% and 27.49% weight compositions of Zn and O, respectively, to further substantiate ZnO nanoparticle synthesis. The BC-ZnONPs showed notable anti-hyperglycaemic properties with IC&lt;sub&gt;50&lt;/sub&gt; of 87.72±5.13 and 124.21±15.20 μg/mL against α-amylase and α-glucosidase, respectively.&lt;strong&gt; Conclusion: &lt;/strong&gt;Black Cumin seed extract was a useful biogenic material for synthesizing ZnO NPs. The BCZnONPs showed promising anti-hyperglycaemic properties based on the notable inhibitory activities against α-amylase and α-glucosidase enzymes. Future work may include evaluating the synergistic effects of black Cumin metabolites and ZnONPs, as well as determining the in vivo toxicity profile for safety considerations.&lt;/p&gt;

It is known that the seeds of these three herbs contain high amounts of antioxidants, which are helpful in disease prevention, but further research is needed on some of their other phytochemical components (terpene alkaloids, benzoquinones and others), which are claimed to affect human opioid receptors. &lt;strong&gt;Methods:&lt;/strong&gt; Seeds from the three afore mentioned plants have been studied by ATR-FTIR vibrational spectroscopy and thermo analytical techniques (TG/DTG, DTA and DSC). &lt;strong&gt;Results:&lt;/strong&gt; The infrared spectrum has confirmed the presence of the ester carbonyl of terpenoid alkaloids (such as nigellamine) and the fully conjugated cyclic dione structure of quinones (e.g., thymoquinone). As regards the thermal stability of these seeds, small differences have been observed in their thermal profiles (endothermic effects at around 333&amp;ordm;C for chia, 268&amp;ordm;C for black cumin and 319&amp;ordm;C for poppy seeds), which can be ascribed to their different content in carbohydrates. &lt;strong&gt;Conclusions:&lt;/strong&gt; The functional groups of the main active constituents and the thermal behavior of these three seeds have been elucidated.&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%">157</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Paula Carri&amp;oacute;n-Prieto,&lt;sup&gt;1&lt;/sup&gt; Pablo Mart&amp;iacute;n-Ramos,&lt;sup&gt;2&lt;/sup&gt;* Salvador Hern&amp;aacute;ndez-Navarro,&lt;sup&gt;1&lt;/sup&gt; Iosody Silva-Castro,&lt;sup&gt;1&lt;/sup&gt; Manuela Ramos- Silva,&lt;sup&gt;3&lt;/sup&gt; Jes&amp;uacute;s Mart&amp;iacute;n-Gil&lt;sup&gt;1 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
