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.
从番石榴叶的甲醇提取物中，分离出(+)-没食子儿茶素，它是一种针对紫外线诱导的大肠杆菌突变的生物抗诱变化合物。这进一步证明了酚类化合物需要三个相邻的羟基才能具备这种活性。
