The results show the increasing number of survived animals in the treated group compared to the negative control group.&lt;strong&gt; Conclussion:&lt;/strong&gt; Both of &lt;em&gt;U. gambir &lt;/em&gt;and &lt;em&gt;U. sclerophylla &lt;/em&gt;prevent pulmonary thromboembolism on mice subjects represent by the increased of survival rate. Antithrombotic effects that were observed suggested was provide by their antiplatelet activity.&lt;/p&gt;

Genus Uncaria is well known for catechin content that has potent antioxidant activity. Uncaria also was reported containing alkaloid that has antihypertensive action. This study aims to provide microscopic characters and phytochemical profiles associated with the phenolic and alkaloid compounds contained in these two species of Uncaria. Methods: Microscopic characteristics were performed on fresh leaf samples using a microscope. Presence of alkaloids from ethanol and chloroform extract of &lt;em&gt;U. gambir&lt;/em&gt; and U. sclerophylla leaf were performed using Dragendorff reagents. Thin Layer Chromatography profile was developed in the mobile phase that consisted of acetone: chloroform (8:2). Total Phenolic Content was determined according to the Folin-Ciocalteu method using microplate reader spectroscopically at λ = 765 nm.&lt;strong&gt; Results:&lt;/strong&gt; Microscopy of &lt;em&gt;U. gambir&lt;/em&gt; leaf revealed the presence of vascular bundle fragment, oil fragments, parenchyma cells, midrib transverse-section and lower epidermis with paracytic stomata. Whereas in &lt;em&gt;U. sclerophylla&lt;/em&gt; can be observed midrib transverse-section and lower epidermis unicellular with trichomes. Both &lt;em&gt;U. gambir&lt;/em&gt; and &lt;em&gt;U. sclerophylla&lt;/em&gt; positively contain alkaloids. Chloroform extract showed the presence of alkaloids while ethanolic extracts showed negative results. The TLC profile shows the presence of catechin compound in the ethanolic extract, whereas in the chloroform extract does not show the presence of catechin. The total phenolic content of &lt;em&gt;U. gambir&lt;/em&gt; and U&lt;em&gt;. sclerophylla&lt;/em&gt; leaf ethanolic extract and chloroform extract was 7.309; 5.734 and 0.437; 0.161 mg of gallic acid equivalents each gram sample, respectively. &lt;strong&gt;Conclusion:&lt;/strong&gt; Microscopic characteristics, TLC and phytochemicals obtained can be used for the authentication of &lt;em&gt;Uncaria gambir&lt;/em&gt; Roxb. and &lt;em&gt;Uncaria sclerophylla&lt;/em&gt; Roxb leaf.&lt;/p&gt;
