<p><strong>Aim:</strong> The present study was aimed to explore the phytochemical constituents present in <em>Laurencia obtusa </em>collected from Tamil Nadu, South India.</p> <p><strong>Methods:</strong> Phytochemical screening of different extracts was carried out using the standard procedure and the results were illustrated.</p> <p><strong>Results:</strong> Steroids show the maximum (4/6) presence in acetone, benzene, chloroform and petroleum ether extracts followed by alkaloids (3/6) in ethanol, acetone and chloroform extracts. The UV-Vis phytochemical profile of various extracts of <em>L. obtusa </em>was tabulated. The qualitative HPLC fingerprint profile of ethanolic extract of<em> L. obtusa</em> was selected at a wavelength of 254 nm due to sharpness of the peaks and proper baseline. The profile displayed one prominent peak at a retention time of 1.953 min and some moderate peaks were observed at a retention time of 3.000, 2.570 and 2.467 min respectively.</p> <p><strong>Conclusion:</strong> The present studies on <em>L. obtusa</em> produced novel phytochemical markers in standardization as useful analytical tools to check not only the quality of the powder but also the presence of adulterants in ayurvedic drugs.</p>
