Abstract

Jamaican E. riparium Regel has been examined and found to contain the new chromene acetovanillochromene (6-acetyl-8-methoxy-2,2-dimethylchromene) as well as methyl-ripariochromene A (6 acetyl-7,8-dimethoxy-2,2-dimethylchromene) previously isolated from an Australian sample of the same species. Confirmation of the structure of methylripariochromene A is reported.
