title: Identification of (+)-gallocatechin as a bio-antimutagenic compound in Psidium guava leaves.
abstract: From the MeOH-extract of guava leaves, (+)-gallocatechin was isolated as a bio-antimutagenic compound against UV-induced mutation in Escherichia coli. This strengthens the evidence that phenolic compounds require three neighbouring-OH groups in order to possess this activity.
