The quality of herbal medicine determine its safety as well as efficacy; and geographical origin is important factor contributing on the quality of herb and its products. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Thin Layer Chromatography (TLC) method combined with chemometric, Principal Component Analysis (PCA), has been employed to evaluate the quality of &lt;em&gt;Orthosiphon stamineus&lt;/em&gt; leaves collected from eleven origins in Indonesia.&lt;strong&gt; Results:&lt;/strong&gt; The results showed that mobile phase suitable for &lt;em&gt;Orthosiphon stamineus&lt;/em&gt; was chloroform, dichloromethane, ethyl acetate (7:4:1). The method used has met the requirements of TLC system stability and precision. TLC-fingerprints analyzed with chemometrics showed an ability to discriminate &lt;em&gt;Orthosiphon stamineus&lt;/em&gt; from various origins. PCA score plot of the first two principal components (PC) clearly distinguished 3 clusters of samples, whereas the loading plot of the first two PC showed that compounds with the Rf values of 0.0-0.1, 0.1-0.2, 0.2-0.3, and 0.9-1.0 are the most important compounds for clustering of samples. &lt;strong&gt;Conclusions:&lt;/strong&gt; TLCfingerprint combined with the PCA was able to discriminate among the leaves of &lt;em&gt;Orthosiphon stamineus&lt;/em&gt; originated from various locations. TLC-fingerprints analyzed with chemometrics can be used as an alternative of marker-oriented method to evaluate the quality of &lt;em&gt;Orthosiphon stamineus.&lt;/em&gt;&lt;/p&gt;

Kaempferol was reported for the first time from &lt;em&gt;Gomphrena serrata&lt;/em&gt;. Quercetin was separated and identified from the hydro alcoholic extracts &lt;em&gt;Alternanthera sessilis&lt;/em&gt; stems (RT 6.503, concentration 0.01mg/ml). The hydroalcoholic extract of &lt;em&gt;Euphorbia heterophylla&lt;/em&gt; stems (RT 6.588, concentration 0.01mg/ml) was also evaluated for the presence of quercetin. &lt;strong&gt;Conclusion:&lt;/strong&gt; The method developed is very useful tool for qualifying and quantifying the plant specimens as well as their extracts.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">439</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mamillapalli Vani&lt;sup&gt;1*&lt;/sup&gt;, Shaik Abdul Rahaman&lt;sup&gt;2&lt;/sup&gt;, Avula Prameela Rani&lt;sup&gt;3 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
