Abstract

Virgatic acid triterpene, extracted from salvia plants, is found to be quenched by singlet oxygen at chemical and photosensitized oxygenations. A charge transfer energy transfer is attributed to the quenching of singlet oxygen, which may be accounted as a protective mechanism of salvia plants to photooxygenations.
