Ms. Abdelkader et al., BIOACTIVE IRIDOIDS AND A NEW LIGNAN FORM ALLAMANDA-CATHARTICA AND HIMATANTHUS-FALLAX FROM THE SURINAM RAIN-FOREST, Journal of natural products, 60(12), 1997, pp. 1294-1297
Bioassay-guided fractionation of the EtOAc extract of both Allamanda c
athartica and Himatanthus fallax (Apocynaceae) using the Sc-7 yeast st
rain resulted in the isolation of the weakly cytotoxic isoplumericin a
nd plumericin. In addition, the new lignan 7(R)-methoxy-8-epi-mataires
inol and three known compounds, plumieride, matairesinol, and pinoresi
nol, were isolated from H.fallax.
