Choisy holds Convolvulaceae family the leafy parts underwent a Soxhlet extraction with ethanol which was then subjected to a phytochemical investigation that shows the presence of alkaloids, phenols, flavonoids, terpenoids, tannins, glycosides saponins, sterols, and carbohydrates. &lt;strong&gt;Material and Methods:&lt;/strong&gt; Firstly, the ethanolic leaf extract is treated with petroleum ether to remove excess lipids, sterols, and impurities. TLC was performed by toluene: ethyl acetate: formic acid and the same solvent system was used for column chromatography. The bands getting separated into the column were collected separately in a test tube. Once the solvent toluene ends, the next solvent system with 18 ml of toluene and 2 ml of ethyl acetate, is introduced into the column, and continues the separation procedure. Collect separated bands and perform TLC of each separate band by using the same solvent system in a concentration of 5:4:1. A single component on a TLC plate with a solvent system of 12 ml toluene and 8 ml ethyl acetate was obtained whose characterization was done by IR, NMR, and mass. &lt;strong&gt;Results: &lt;/strong&gt;The RF value of Rutin is 0.17 which correlates with the Retention factor of ethanolic leaf extracts of RH by HPTLC comparative studies and a compound was isolated by column chromatography. &lt;strong&gt;Conclusion: &lt;/strong&gt;These studies have concluded that a compound is separated by means of HPTLC and spectroscopic interpretation and identified as Rutin.&lt;/p&gt;
