Terpenoids and phenolics of Micromeria persica.

Phytochemical investigation of the aerial parts of Micromeria persica led to the isolation of a new oleane type triterpenoid ester (1), together with six known compounds 2-7), comprising one phenyl ethanoid ester, one glycosylated flavonoid, two triterpenoids, and two steroids. Their structures were elucidated by interpretation of their one-dimensional and two-dimensional NMR spectra and completed by the analysis of the HRESIMS data. Compounds 1 and 3 were evaluated for their cytotoxic feature against human breast adenocarcinoma cell line (MDA-MB231) and human prostate cancer cell line (DU145). However, they did not show positive effect (IC₅₀ > 75µM).
