General description

5,7-dimethoxycoumarin is isolated and identified from leaves and fruits of Pelea anisata H. Mann, a plant whose fruit are used in the construction of mohikana leis. It induces frameshift mutagenesis in bacteria. It also causes lethal photosensitization and the formation of sister chromatid exchanges in Chinese hamster cells.

Biochem/physiol Actions

5,7-Dimethoxycoumarin induces the processes of differentiation and melanogenesis in murine (B16) and human (A375).

To study the chemical constituents from Lobelia chinensis. The constituents were extracted with 95% EtOH, partitioned with different solvents, and isolated and purified by silica gel column chromatography and crystallization, their structures were elucidated by physico-chemical properties and spectroscopic data.

A new C-8 prenylated 5,7-dimethoxycoumarin named omphamurrayin was isolated from the leaves of Murraya paniculata var. omphalocarpa, and its structure was established as 5,7-dimethoxy-8-(1-oxo-2-senecioyl-3-methyl-3-butenyl)-2H-1-benzopyran-2-one on the basis of the spectroscopic evidence. The taxonomic status of M. paniculata var. omphalocarpa is
