Background and objectives: The cholinergic deficit correlates with the severity of Alzheimer’s disease. The cholinergic function can be improved by AChE inhibitors blocking this key enzyme in the breakdown of acetylcholine. Based on traditional medicine, during two last decades the use of herbal medicinal substances in dementia therapy has been studied. The fruit extract of <em...
متن کاملBioactivity-guided isolation of cytotoxic constituents from three medicinal plants.
CONTEXT The ethanol extracts and their fractions of three Indian medicinal plants, Ervatamia coronaria (Jacq.) Stapf, (Apocynaceae), Mimosa pudica L. (Mimosaceae) and Caesalpinia bonduc (L.) Roxb. (Caesalpiniaceae) were tested for their cytotoxic activity in the brine shrimp lethality (BSL) bioassay and in various cancer cell lines. The plants were selected based on their traditional use in the...
متن کاملBioactivity-guided isolation of antiproliferative compounds from Centaurea carduiformis DC
In this study, antiproliferative activity of methanol extract of Centaura carduiformis DC. subsp. carduiformis var. carduiformis DC (CC) was examined against Vero, HeLa and C6 cell lines in 1000 and 500 mg/mL concentrations using the BrdU ELISA assay. The CC root (CCR) has the most effective antiproliferative activity. The root extract was fractionated using various solvent and determined antip...
متن کاملBioactivity-guided isolation of anticancer agents from Bauhinia kockiana Korth.
BACKGROUND Flowers of Bauhinia kockiana were investigated for their anticancer properties. METHODS Gallic acid (1), and methyl gallate (2), were isolated via bioassay-directed isolation, and they exhibited anticancer properties towards several cancer cell lines, examined using MTT cell viability assay. Pyrogallol (3) was examined against the same cancer cell lines to deduce the bioactive func...
متن کاملIn vitro Antibacterial Activity of Piper Longum
In this study the attempt was made to evaluate the antimicrobial activity of various solvent extracts of fruit of Piper longum L. against different gram positive and gram negative bacteria by using disk diffusion method. The petroleum ether extract was resistant towards all the tested bacterial strains while ethyl acetate was highly active. Among all the gram positive bacteria Staphylococcus au...
