Abstract

The roots and basal stems of Bromelia pinguin L. contain the flavonoids penduletin, cirsimaritin, and casticin, as well as isoferulic acid and three new diterpenoids. Two of these are the novel phyllocladane derivatives 3-oxophyllocladan- 16f-ol and phyllocladan- 16α,19-diol, and the third is 3-oxopimar-15-ene-7β,8β-diol. The major cytotoxic activity of the extracts of B. pinguin is probably due to the flavonoids.
