The sapogenins were isolated from the roots of &lt;em&gt;H. isora.&lt;/em&gt; RP-HPLC method was developed and validated for estimation of oleanolic acid from the sapogenins of roots of &lt;em&gt;H. isora.&lt;/em&gt; &lt;strong&gt;Results:&lt;/strong&gt; Detailed quality control parameters of roots of &lt;em&gt;H. isora&lt;/em&gt; were reported. Total content of oleanolic acid was 0.075%w/w from roots of &lt;em&gt;H.&lt;/em&gt; &lt;em&gt;isora determined&lt;/em&gt; by HPLC. &lt;strong&gt;Conclusion:&lt;/strong&gt; The present study is useful for accurate identification and authentication of roots of &lt;em&gt;H. isora.&lt;/em&gt; The HPLC method for determination of oleanolic acid from the roots of &lt;em&gt;H. isora &lt;/em&gt;is efficient, precise, reliable and sensitive and can be adopted for routine analysis.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">523</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Pinal A.
