Elemental pattern of TPC was developed in order to investigate the identity and quality of commercial TPC drugs. &lt;strong&gt;Method:&lt;/strong&gt; Inductively coupled plasma mass spectrometry (ICP-MS) was used for the quantitative determination of ten essential and trace elements in five marketed samples of &lt;em&gt;Triphala churna&lt;/em&gt;. The concentration patterns of these elements were deciphered by multivariate statistical analysis such as hierarchical cluster analysis (HCA), fuzzy c-means (FCM) and k-means (KM) cluster analysis. &lt;strong&gt;Results:&lt;/strong&gt; The elemental concentrations ranged from 1.3 mg/kg (Cr, TPC3) to 14220 mg/kg (K, TPC4). The elemental fingerprint of &lt;em&gt;Triphala churna&lt;/em&gt; was established based on three churnas viz. TPC1, TPC3 and TPC5, which were found in one cluster with a very high degree of similarity by KM, FCM and HCA techniques. &lt;strong&gt;Conclusion:&lt;/strong&gt; Based on the results, the graphical pattern of elements detected in these samples can be considered as elemental fingerprint of &lt;em&gt;Triphala churna&lt;/em&gt; and can be used for authentication and/or to determine the quality of commercial TPC drugs.&amp;nbsp;&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">117</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Venkata Siva Satyanarayana Kantamreddi&lt;sup&gt;1&lt;/sup&gt;&lt;sup&gt;,2&lt;/sup&gt;*, Thirumala Veni Vasupalli&lt;sup&gt;1&lt;/sup&gt;, Murali Krishna Malasani&lt;sup&gt;2&lt;/sup&gt;, and Simhachalam Boddana&lt;sup&gt;3&lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
