As a part of screening studies for cancer chemopreventive agents (anti-tumor promoters) 33 Dryopteris phlorophenone derivatives have been evaluated. The compounds tested comprised of monomeric acylphloroglucinols (e.g. desaspidinol, aspidinol) as well as dimeric (e.g. aspidin, desaspidin), trimeric
Fractionation of the chloroform-soluble extract of the leaves and twigs of Calyptranthes pallens, collected from an experimental plot in a hardwood forest of southern Florida, using a hormone-dependent human prostate carcinoma (LNCaP) tumor cell line, led to the isolation of a phloroglucinol
One new coumarin, dryofracoumarin A (1), and eight known compounds 2-9 were isolated from Dryopteris fragrans (L.) Schott. Their structures were established on the basis of extensive spectroscopic data analyses and comparison with reported spectroscopic data. The new compound 1 was determined to be
