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;
