  The organic extract of Avrainvillea longicaulis had antioxidant activity surpassing or equivalent to that of commercially available antioxidants (butylated hydroxytoluene, butylated hydroxyanisole and alpha-tocopherol).
  
  Avrainvillea erecta was reported to have strong hemagglutination activity. In addition, the chloroform fraction of a methanol extract of Avrainvillea erecta exhibited hydrogen peroxide scavenging activity as strong as that shown by gallic acid.
