Leaves have a sour taste and have been used in Thai remedies for wound healing, diuretic, dysentery and emmenagogue. &lt;strong&gt;Objective:&lt;/strong&gt; This study aimed to focus on pharmacognostic specification and quantitative analysis of quercetin and quercitrin in &lt;em&gt;B. malabarica&lt;/em&gt; leaves. &lt;strong&gt;Methods:&lt;/strong&gt; Various methods such as macroscopic and microscopic evaluations of &lt;em&gt;B. malabarica&lt;/em&gt; leaf were studied along with physico-chemical parameters and quantitated quercetin and quercitrin using RP-HPLC. &lt;strong&gt;Results and Conclusion:&lt;/strong&gt; Whole plant, structures of dried powder crude drug, cross section of midrib and leaf measurement were established. Paracytic stomata and multicellular trichome were found on lower epidermis. &lt;em&gt;B. malabarica&lt;/em&gt; leaves from 15 sources throughout Thailand were examined the pharmacognostic specification according to WHO guideline. Physico-chemical parameters showed that loss on drying, total ash, acid insoluble ash and water content should not be more than 8.00, 7.08, 1.79 and 8.28 % of dry weight while ethanol and water soluble extractive values should not be less than 13.78 and 16.47 % of dry weight respectively. Quercetin and quercitrin were the markers for quantitative analysis using RP-HPLC with diode array detector in &lt;em&gt;B. malabarica&lt;/em&gt; ethanolic extract. Quercetin and quercitrin contents were found to be 0.18 g and 0.38 g in 100 g of dried crude drug. Method validation was determined according to ICH guideline. All results were in the acceptable range and could be used for identity, safety, efficacy and quality of &lt;em&gt;B. malabarica&lt;/em&gt; leaves in Thailand.&lt;/p&gt;
