Hypolepis punctata

Using the modified Ames mutagenic test and two-dimensional thin-layer chromatography (317), Natori s group found that many of the pterosin- and pteroside-containing pteridaceous ferns contained ptaqui-loside-like compounds as well (282). Ptaquiloside (466) itself was found also in Pteris cretica L. (282) and the mutagenic hypolosides A (416), B (417), and C (418) were isolated from Hypolepis punctata. These compounds easily produce pterosin Z (419) when treated with alkali (258). [Pg.54]

Hypacrone (415) is a bitter principle of Hypolepis punctata. It gives pterosin H (423) and pterosin Z (419) by treatment with 4N-HC1 and pterosin Z (419) when treated with 10% H2SO4. (257). [Pg.54]
