Arbutin may be included as active compounds in the plants. The chemometric analysis is used to identify the similarity of functional groups found in arbutin and that are in &lt;em&gt;Paederia foetida&lt;/em&gt; and &lt;em&gt;Vitis vinifera. &lt;/em&gt;Materials and Method: The ethanol extracts of &lt;em&gt;Paderia foetida&lt;/em&gt; and &lt;em&gt;Vitis vinifera&lt;/em&gt; were subjected to compound partition and characterization. Then a liquid-liquid partition is carried out using n-hexan and water solvents, followed by ethyl acetate and water partitions. This procedure is carried out continuously until the top layer is cleared. Partitioned compounds were analyzed using FTIR spectroscopy to identify functional groups. Furthermore, it was analyzed using the chemometric method (Principal Component Analysis and Cluster Analysis). &lt;strong&gt;Results: &lt;/strong&gt;From the results of FTIR spectroscopy, functional groups in &lt;em&gt;Paederia foetida&lt;/em&gt; and&lt;em&gt; Vitis vinifera &lt;/em&gt;were identical to functional groups found in arbutin. PCA Analysis was achieved using principal component accounting an eigenvelue about 99,3 % of the total variance. &lt;strong&gt;Conclusions: &lt;/strong&gt;CA analysis showed that compounds in &lt;em&gt;Paederia foetida &lt;/em&gt;(Euclidean distance 0.537) and&lt;em&gt; Vitis Vinifera &lt;/em&gt;(Euclidean distance 1.157) may be similar with arbutin.&lt;/p&gt;
