On the other hand, fingerprinting analysis and quantification of major flavonoids of 184 cultivars were performed by high-performance liquid chromatography (HPLC). Among twenty five (25) components which were detected and separated: ten were corresponding to quercetin 3-Oglucosyl- rhamnoside (Rt=23.5), quercetin 3-O-glucoside (Rt=25), kaempferol 3-O-glucosylrhamnoside and its acylated derivative (Rt=32), kaempferol 3-O-glucoside (Rt=33), quercetin 3-O-p.coumaroyl-diglucoside (Rt=37), quercetin 3-O-P.coumaroyl-glucoside (Rt=40.5), quercetin (Rt=41.5), kaempferol and its acylated derivative (Rt=47). Only non-acylated glycosides of quercetin and kaempferol contributed to chemical variations among different cultivars based on the results of PCA. &lt;strong&gt;Conclusion:&lt;/strong&gt; The genus &lt;em&gt;Begonia&lt;/em&gt; is very heterogeneous and it is possible to distinguish several chemotypes whose differences rely on the complementarities between the metabolic pathways involved in the biosynthesis of glycosides of quercetin and kaempferol.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">850</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Saffidine Karima&lt;sup&gt;1*&lt;/sup&gt;, Chirol Nadine&lt;sup&gt;2&lt;/sup&gt;, Benayache Fadila&lt;sup&gt;3&lt;/sup&gt;, Jay Maurice&lt;sup&gt;2&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;

Pharmacological studies on the bark, root, leaf and fruit extracts of this species support their significance as antioxidants, as well as their efficacy on diuretic, antibacterial, anti-fungal and antiulcer activity. &lt;strong&gt;Methods:&lt;/strong&gt; The present study focused on microscopic study, phytochemical analysis, HPLC and HPTLC finger print evaluation of leaf and stem wood extracts. &lt;strong&gt;Results:&lt;/strong&gt; Microscopic analysis demonstrates its characteristic parameters namely hairy trichomes, pearl glands, vascular bundles, epidermis and is expected to assist easy identification of the genus. &lt;strong&gt;Conclusion:&lt;/strong&gt; The solvent system, chloroform:methanol (8:2) was found to be the best as TLC eluent to visualize all major components of this species. HPLC and HPTLC finger prints not only confirm the presence of two major components, oxyresveratrol and artocarpin in stem wood extract, but also prove their absence in the leaf extract.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">887</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mahadeva Nayak&lt;sup&gt;1&lt;/sup&gt;, Ananthanarayanan Nagarajan&lt;sup&gt;1*&lt;/sup&gt;, Muhammed Majeed&lt;sup&gt;1,2&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;

Fruit was subjected to various pharmacognostical investigations, Extraction procedures, and preliminary phytochemical screening, according to WHO guidelines. Ethanolic extract was standardized to total phenolic and flavonoid content, followed by phytochemical quantification of &lt;em&gt;P. pashia&lt;/em&gt; extract using lupeol as a chemical marker by HPLC method. &lt;strong&gt;Results: &lt;/strong&gt;In the present study, microscopy of the fruit showed typical characteristics of berry, having thick fleshy pericarp differentiated into thin epicarp and thick mesocarp having wide radiating carpel chambers with one or two seeds attached in axile placentum. Further, physicochemical evaluation was done like, loss on drying, total ash value, acid insoluble ash value, water soluble ash value, fluorescence analysis etc. Heavy metal and pesticide residue analysis was also performed. Furthermore, ethanolic extract of &lt;em&gt;Pyrus pashia&lt;/em&gt; (EPP) obtained from cold maceration and phytochemical screening of different fractions obtained by liquid partitioning revealed the presence of various secondary metabolites such as glycosides, steroids, triterpenoids, phenols flavonoids etc. Moreover, the total phenolic content and total analysis revealed that fruits are rich source of phenols and flavonoid. The HPLC chromatogram suggested that EPP contained 4.24% w/w of lupeol. &lt;strong&gt;Conclusion:&lt;/strong&gt; Pharmacognostical and phytochemical investigation will ensure quality and safety of this medicinal plant, furthermore HPLC quantification will aid in authentication and development of monograph.&lt;/p&gt;
