1) The document reports on the isolation and identification of anti-amyloid compounds from Psychotria plant extracts. 2) An extract of P. stenostachya was found to contain the anti-amyloid compound hydroquinone, which was isolated using HPLC and identified through crystallography. 3) Extracts of P. remota and P. alba also exhibited anti-amyloid activity, but the active components in P. remota were not fully isolated or identified. Fractionation by HPLC suggested the presence of multiple active constituents in P. remota extract.
