Biological Activities

Compounds

Conditions

Rheum lhasaense contains specific stilbenoids that exhibit a significant inhibitory effect on acetylcholinesterase. Research indicates that these components are isolated based on their acetylcholinesterase inhibition activity, with certain compounds showing high inhibitory abilities on AChE. By targeting these biochemical pathways, the plant effectively treats cognitive impairment in models such as scopolamine-induced mice. Specifically, the compound piceatannol-3'-O-β-D-glucopyranoside plays a key role in ameliorating memory loss and dysfunction. Ultimately, the medicinal properties of Rheum lhasaense help treat the inhibitory abilities on acetylcholinesterase to mitigate neurodegenerative symptoms.

Preparations

Parts used

Rheum lhasaense contains various bioactive compounds that are primarily concentrated within its root system. Scientific investigations have successfully isolated several new resveratrol oligomer derivatives and stilbenoids from the methanolic and ethanolic extracts of these roots. These chemical constituents, including specific dimers and monomeric stilbene glycosides, are identified through advanced spectroscopic analysis. Research highlights that components found in the roots exhibit significant potential for scavenging DPPH radicals. Furthermore, certain isolated substances from the plant's roots have demonstrated notable inhibitory activity against the enzyme acetylcholinesterase.
