Lipoxygenase Inhibitory Activity of Korean Indigenous Mushroom Extracts and Isolation of an Active Compound from Phellinus baumii
We investigated a total of 335 samples of Korean native mushroom extracts as part of our lipoxygenase (LOX) inhibitor screening program. Among the mushroom-methanolic extracts we investigated, 35 exhibited an inhibitory activity greater than 30% against LOX at a concentration of 100 µg/mL. Especially, Collybia maculata, Tylopilus neofelleus, Strobilomyces confusus, Phellinus gilvus, P. linteus,...
متن کاملTerpene glycosides and cytotoxic constituents from the seeds of Amomum xanthioides.
Column chromatographic isolation of the MeOH extract of the seeds of Amomum xanthioides afforded a new diterpene glycoside, amoxanthoside A (1), two new monoterpene glycosides, (1 S,4 S,5 S)-5- EXO-hydroxycamphor 5-O-beta-D-glucopyranoside (2) and (1 R,4 R,5 S)-5-ENDO-hydroxycamphor 5-O-beta-D-glucopyranoside (3), together with four known compounds, hedychiol A (4), pygmol (5), (1 S,4 R,6 R)-(+...
متن کاملAntipoliovirus Activity of the Organic Extract of Eupatorium buniifolium: Isolation of Euparin as an Active Compound
The antiviral activity of the organic extract (OE) of Eupatorium buniifolium against poliovirus type 1 was determined by in vitro assays with an effective concentration 50 (EC50) of 23.3 ± 3.3 µg/mL. Bioassay-guided fractionation of the OE allowed the isolation of an active principle that was identified by spectroscopic methods ((1)H- and (13)C-NMR, EI-MS, UV, and IR spectroscopy) as the benzof...
متن کاملGlucosidase inhibitory activity and antioxidant activity of flavonoid compound and triterpenoid compound from Agrimonia Pilosa Ledeb
BACKGROUND In Chinese traditional medicine, Agrimonia pilosa Ledeb (APL) exhibits great effect on treatment of type 2 diabetes mellitus (T2DM), however its mechanism is still unknown. Considering that T2DM are correlated with postprandial hyperglycemia and oxidative stress, we investigated the α-glucosidase inhibitory activity and the antioxidant activity of flavonoid compound (FC) and triterpe...
متن کاملDifferentiation and Apoptosis of U937 Leukemia Cells by an Active Compound from Dendrostellera lessertii
Background: Regarding the strong differentiation and anti-leukemic activity of Dendrostellera lessertii extract, an active agent with similar capabilities was isolated from the crude extract of the plant leaves. The aim of this study was to determine whether the anti-proliferative effect observed for this compound, is differentiation-dependent among the drug-treated cells, using U937 cells. Me...
