Evaluation of anticholinesterase effect of some species and quantification of hyperoside by HPLC.

This article presents the evaluation of anticholinesterase effects of aerial parts of , and and isolated flavonoids from , and quantification of the flavonoids by HPLC. Besides, the highest acetylcholinesterase inhibition was seen in the EtOAc sub-extracts of and (36.51 ± 1.88 and 39.89 ± 3.09%, respectively), whereas EtOAc sub-extract of had the best butyrylcholinesterase inhibition (62.09 ± 1.98%). Hyperoside showed strong inhibition activity on both enzymes. The active EtOAc sub-extract of was quantitatively analyzed for their content of hyperoside (quercetin-3---D-galactoside) by HPLC. The content of hyperoside in EtOAc sub-extract of was detected as 3.312%. The anatomical structures of the stem, leaf, sepal, petal, anther, and filament of were investigated. The anatomical properties given in this study provide a description of .[Formula: see text].
