New terpenoids from Maytenus blepharodes.
Three new terpenoids, xuxuarine Ealpha (1), a triterpene dimer based on two pristimerin units, and two sesquiterpenoids with a dihydro-beta-agarofuran skeleton (2 and 3) were isolated from Maytenus blepharodes. Their structures were elucidated on the basis of spectral analysis, including homonuclear and heteronuclear correlation NMR experiments (COSY, ROESY, HMQC, and HMBC). The absolute configurations of 1 and 2 were determined by CD studies.
