TL;DR: The results suggest that the anticonvulsive effect of this AGR oil is originated by the enhancement of GABA level in the mouse brain, because convulsion depends partially on GABA concentration which can be properly preserved by inhibiting GABA transaminase.

TL;DR: Antimutagenic activity-guided fractionation of an extract prepared from the thorns of Gleditsia sinensis LAM led to the isolation of one triterpenoid and four steroids, which were identified as D:C-friedours-7-en-3-one, stigmast-4-ene-3,6-dione, stigmasterol and beta-sitosterol.

TL;DR: Ten phenylethanoid glycosides significantly attenuated glutamate-induced neurotoxicity at concentrations ranging from 0.1 to 10 microM and a new compound was isolated from the n-BuOH fraction of Callicarpa dichotoma Raeuschel.

TL;DR: Bioactivity-guided fractionation of the total methanolic extract resulted in the isolation and identification of two active stilbene oligomers, (+)-alpha-viniferin and kobophenol A, which inhibited AChE activity in a dose-dependent manner.

TL;DR: Studies revealed that at the concentration of 10 μM, scopoletin significantly preserved glutathione content by 50% and the activity of superoxide dismutase by 36% and also inhibited the production of malondialdehyde to the degree as seen in the control.
