Hyperoside, also known as quercetin-3-O-?-D-galactopyranoside, belongs to the class of flavonol glycosides. Its aglycon is quercetin, and sugar base galactopyranoside. It made quercetin. The O atom at 3rd position element connected group by a ?-glycosidic bond. Hyperoside, which widely present in planted objects, such fruits whole plants Hypericaceae, Rosac...

DNA barcoding is expected to be one of the most promising tools in biological taxonomy. However, there have been no agreements on which core barcode should be used in plants, especially in species-rich genera with wide geographical distributions. To evaluate their discriminatory power in large genera, four of the most widely used DNA barcodes, including three plastid regions (matK, rbcL, trnH-p...

What causes flowers to diverge? While a plant’s primary pollinator should strongly influence floral phenotype, selective pressures may also be exerted by other flower visitors or competition with other plants for pollination. Species of the primarily bat-pollinated genus Burmeistera (Campanulaceae) frequently cooccur, with up to four species in a given site, and broadly overlap in flowering phe...
