One new aurone, one new isoaurone, damaurones A and B (1 and 2), and five known compounds (3-7) were isolated from the flowers of Rosa damascena. Their structures were elucidated by spectroscopic methods, including extensive 1D- and 2D- NMR techniques. Compound 1 is the first naturally occurring aurone derivatives bearing an acetyl group. Compounds 1-7 were tested for their anti-HIV-1 activities and cytotoxicities. The results showed that compound 1 has significant potential anti-HIV-1 activity with therapeutic index (TI) values above 80, and showed high cytotoxicities against NB4 and MCF7 cell with IC50 values of 3.4 and 2.6 μM, respectively.
