Abstract

The behavior of the triterpenes friedelin and friedelan-3-ol, contained on the leaves ofMaytenus aquifolium Martius (Celastraceae), upon several doses of X- and γ-rays (10 to 100 kGy), was investigated by high resolution gas chromatography (HRGC) and high resolution, gas chromatography —mass spectrometry (HRGC-MS). The friedelin content has not changed with γ-irradiation, but the content of friedelan-3-ol decreased around 17% at doses of 10, 20 and 40 kGy and around 27% at doses of 60, 80 and 100 kGy. The levels of both triterpenes remained unchanged even, at higher X-ray doses. Lupen-3-one was detected by HRGC-MS.
