Previous research has revealed that &lt;em&gt;A. crassna&lt;/em&gt; leaves contain mangiferin as an active compound. Although the active component has been investigated, the pharmacognostic specification and quantification of mangiferin from &lt;em&gt;A. crassna&lt;/em&gt; leaves have never been established. &lt;strong&gt;Objective:&lt;/strong&gt; The current study aimed to conduct and develop a pharmacognostic standard according to WHO guidance as well as the validated method for quantifying mangiferin content. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Dried &lt;em&gt;A. crassna&lt;/em&gt; leaves from 15 separated locations throughout Thailand were investigated for pharmacognostic specification. Their mangiferin contents were quantitatively analysed by TLC densitometry with win CATS software. &lt;strong&gt;Results:&lt;/strong&gt; Macroscopic-, microscopic- characteristics and TLC fingerprinting combined with physicochemical parameters were reported in this study. The loss on drying, moisture content, and total ash content as well as acid-insoluble ash content were determined to be 8.62 &amp;plusmn; 0.13, 8.16 &amp;plusmn; 0.14, 6.82 &amp;plusmn; 0.09 and 1.49 &amp;plusmn; 0.03%, respectively. Ethanol- and waterextractive values were found to be 9.05 &amp;plusmn; 0.39 and 16.94 &amp;plusmn; 0.22 %, respectively. In addition, the validation method for quantifying the mangiferin content was developed. The contents of mangiferin in A.&lt;em&gt; crassna&lt;/em&gt; leaf extract determined by TLC-densitometry and TLC-image analysis were found to be 1.2992 &amp;plusmn; 0.5980 and 1.3036 &amp;plusmn; 0.5874 % by dried weight, respectively. The results between these two analytical methods were shown to have an insignificant difference. &lt;strong&gt;Conclusion:&lt;/strong&gt; This study provides the necessary information for authentication and standardisation of &lt;em&gt;A. crassna &lt;/em&gt;leaves.&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%">293</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Worathat Thitikornpong&lt;sup&gt;1&lt;/sup&gt;, Boonsri Ongpipattanakul&lt;sup&gt;2&lt;/sup&gt;, Chanida Palanuvej&lt;sup&gt;1&lt;/sup&gt;, Nijsiri Ruangrungsi&lt;/strong&gt;&lt;sup&gt;&lt;strong&gt;1,3*&lt;/strong&gt; &lt;br /&gt;&lt;/sup&gt;&lt;/p&gt;
