Standardization of herbal drugs using chromatographic techniques is essential to ensure quality and reproducibility. &lt;strong&gt;Objective:&lt;/strong&gt; To develop an HPTLC fingerprint profile of &lt;em&gt;Euphorbia prostrata&lt;/em&gt; and to comparatively evaluate densitometric detection of quercetin at 254 nm and 366 nm. Materials and &lt;strong&gt;Methods:&lt;/strong&gt; Methanolic extracts of raw &lt;em&gt;Euphorbia prostrata&lt;/em&gt;, and its inhalation formulation were subjected to HPTLC using silica gel 60 F254 plates. The mobile phase consisted of toluene: ethyl acetate (7:3 v/v). Densitometric scanning was performed at 254 nm and 366 nm using a CAMAG TLC scanner. Chromatographic profiles, Rf values, and peak areas were recorded and compared with quercetin standard. &lt;strong&gt;Results: &lt;/strong&gt;Distinct chromatographic fingerprints were obtained at both wavelengths. The quercetin standard exhibited a characteristic Rf value which corresponded with peaks observed in plant samples. Detection at 366 nm demonstrated improved selectivity and enhanced visualization of flavonoid-related bands compared to 254 nm. Comparative densitometric analysis revealed variation in peak distribution and intensity between raw drug and inhalation formulation. &lt;strong&gt;Conclusion: &lt;/strong&gt;The developed HPTLC fingerprint method provides a reliable tool for qualitative standardization of &lt;em&gt;Euphorbia prostrata&lt;/em&gt;. Comparative wavelength analysis suggests 366 nm to be more suitable for selective flavonoid detection.&lt;/p&gt;
