摘要

Flavonoids in the leaves of Phytolacca americana (Phytolaccaceae), which is native to North America and growing in Japan as a cosmopolitan weed, were surveyed. They were isolated by paper, column and high performance liquid chromatography, and identified as kaempferol 3-O-glucoside, quercetin 3-O-glucoside and kaempferol 3-0-apiofuranosyl-(l->2)-glucoside by UV spectral survey, acid hydrolysis, LC-MS, !H and 13C NMR, and direct TLC and HPLC comparisons with authentic samples. The species exclusively synthesizes the betalain pigments and can not make anthocyanins, which are major pigments in almost vascular plants. However, it was reconfirmed by this survey that P. americana can make flavonol glycosides which biosynthetically related to anthocyanins. Moreover, it was presumed by comparisons with the previous reports that the geographic chemical variations are produced in the species.
