Screening of extracts from the Texas plant Chamaesaracha coniodes (Dun.) Britt. exhibited activity in a cytotoxicity assay bioassay-guided fractionation led to the isolation and structure elucidation of two constituents, conioidines A and B (Chan et al. 1993). The i after the o ought to be unnecessary because the correct species epithet is coniodes (not conioides as has been reported). These compounds are A-n-decanoylhygroline esters with tiglic acid (conioidine A) and its 4-hydroxy congener (conioidine B), respectively (Fig. 3.7). Stereochemistry at C-2 and at C-2, respectively, remains to be determined.
