    Description: (+)-Erythristemine shows moderate toxicity to brine shrimp (LC50 23 ppm) and moderate (IC50=86microg/ml) radical scavenging properties against stable 2,2-diphenyl-1-picrylhy--drazyl (DPPH) radical.
    In vitro:

    Erythrinaline alkaloids from the flowers and pods of Erythrina lysistemon and their DPPH radical scavenging properties.[Pubmed: 15231413]
    (+)-Erythristemine (14) was found distributed in most of the plant parts investigated.
    METHODS AND RESULTS:
    Preliminary work on the crude chloroform/methanol (1:1) showed moderate toxicity to brine shrimp (LC50 23 ppm) and moderate (IC50 86 microg/ml) radical scavenging properties against stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. The DPPH radical scavenging properties of the isolated compounds were assessed using TLC autographic and spectrophotometric assays whereupon only compounds 11 (1 microg; 90 microg/ml) and 12 (0.1 microg; 160 microg/ml) showed any notable activity.
    CONCLUSIONS:
    It appears the two compounds are slow reacting and do not reach steady state conditions within the standard half an hour time frame but only seemed to have reached steady state conditions after 4 h.
