Search for Stress Compounds in Crude Drugs

Stress compounds induced in plant tissues of medicinal plants during the processing of raw materialwere shown as potential constituents of crude drugs. Since stress compounds show biologicalactivities,evaluation of the compounds in crude drugs is very important . Bioassay-directed fractionation of来自药物或相关plants的压力tissues of the stressed tissues of medicinal or相关plants resulted in the isolation ofstress compounds required for authentic analysis .Umbelliferae：Glehnia littoralis, Saposhinikovia divaricata, Angelica acutiloba，and A. acutiloba var. sugiyamae gave psoralen and相关的furanocoumarins；Cnidium officinale gave senkyunolide B. Araceae：Amorphophalus konjac gave two pyrrolidine alkaloids；Colocasia esculenta gave 1 pyrrolidine alkaloid and 3 piperidine alkaloids；Pinellia ternata gave 1 piperidine alkaloid. Paeonia lactiflora gave hederagenin. Acanthopanaxdivaricatum gave scoparone and 2c divaricatum gave D2butenolides. Rheum palmatum gave 3 anthraquinones and 1bianthrone as stress compounds。

Stress compounds induced in plant tissues of medicinal plants during the processing of raw material were shown as potential constituents of crude drugs. Since stress compounds show biological activities, evaluation of the compounds in crude drugs is very important . Bioassay-directed fractionation of plant extracts from the stressed tissues of medicinal or related plants resulted in the isolation of stress compounds required for authentic markers of crude drug analysis .Umbelliferae: Glehnia littoralis, Saposhinikovia divaricata, Angelica acutiloba, and A. acutiloba var. sugiyamae gave psoralen and related furanocoumarins; Cnidium officinale gave senkyunolide B. Araceae: Amorphophalus konjac gave two pyrrolidine alkaloids; Colocasia esculenta gave 1 pyrrolidine alkaloid and 3 piperidine alkaloids; Pinellia ternata gave 1 piperidine alkaloid. Paeonia lactiflora gave hederagenin. Acanthopanax divaricatum gave scoparone and 2 CィイD217ィエD2butenolides. Rheum palmatum gave 3 anthraquinones and 1 bianthrone as stress compounds.
