Other claims from this paper (9)
- Observation Ferulic acid predominated in the ethanolic extract of Deglat nour seeds.
- Observation Flavonoid glycosides such as rutin, isoquercetin and hesperidin were detected, with the highest levels in DNS.
- Observation DNS and GG were the most antibacterial extracts, the other fractions moderate to weak.
- Association The strongest effects matched higher phenolic and flavonoid levels (catechin, quinic acid, isoquercetin), which the authors suggest drive the activity.
- Observation The DNS extract inhibited acetylcholinesterase with an IC50 of 3.17 +/- 0.11 ug/mL.
- Observation The DNS extract inhibited butyrylcholinesterase with an IC50 of 52.55 +/- 0.72 ug/mL.
- Observation DNS AChE inhibitory activity was stronger than that of the reference standard galantamine (IC50 5.01 +/- 0.11 ug/mL).
- Observation DNS BChE inhibition was comparable to the standard (IC50 53.90 +/- 0.56 ug/mL).
- Observation The Deglat nour spikelet extract showed selective BChE inhibition (IC50 43.28 +/- 0.83 ug/mL), more potent than galantamine.
