During the large-scale isolation of the batzelladines A and B, which are inhibitors of gp120-CD4 binding, we isolated 19 minor guanidine alkaloids. Three new tricyclic guanidine alkaloids isolated from this group were named 8a,8b-dehydroptilocaulin (

Bioassay-guided fractionation of the MeOH/CH2Cl2 extract of the roots of Caesalpinia pulcherrima yielded four novel dibenzoate diterpenes, pulcherrimins A, B, C and D (1–4). The structures of these compounds including their absolute configuration w
