(Asteraceae) is studied by us for the first time. We have established its diuretic and antimicrobial action. The study of essential oil and the anatomical structure of &lt;em&gt;S. caucasica&lt;/em&gt; flowers is presented for the first time in this article.&lt;strong&gt; Materials and Methods:&lt;/strong&gt; &lt;em&gt;S. caucasica&lt;/em&gt; flowers were collected at the beginning of flowering in the botanical garden of the Pyatigorsk Medical and Pharmaceutical Institute. Essential oil was obtained by hydro distillation. The component composition of the essential oil was studied by liquid chromatography&amp;ndash;mass spectrometry. Results: The main components of essential oil and microscopic diagnostic signs of &lt;em&gt;S. caucasica&lt;/em&gt; flowers were established. &lt;em&gt;Solidago&lt;/em&gt; &lt;em&gt;caucasica&lt;/em&gt; flowers contain 0.57% essential oil. It contains humulene epoxide H (-)-spathulenol, &amp;beta;-linalool, &amp;alpha;-terpinol, trans-geraniol, carvacrol and others. Numerous pappus hairs meet in the microscopy of the flower. Ligulate florets are characterized by round chromoplasts, covering trichomes multicellular. Epidermal cells of the tubular florets have polygonal chromoplasts, trichomes, consisting of several cells fused with each other, covering trichomes with a thick wall and a thin cavity inside. On the epidermis of the involucre there are stomata of anomocytic type, glandular trichomes, trichomes cone-shaped, trichomes wide and essential oil glands. &lt;strong&gt;Conclusion:&lt;/strong&gt; The obtained standards will provide referential information for correct identification, purity, standardization and preparation of monograph of&lt;em&gt; S. caucasica&lt;/em&gt;.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s63</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Victoria Vladimirovna Fedotova, Dmitry Alexeevich Konovalov&lt;sup&gt;* &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
