摘要
The aerial parts of the Egyptian herb Cornulaca monacantha have yielded two new galloyltannin analogs (named monacanthin A and monacanthin B) characterized by protoctechuoyl moiety at C-6, and also a new flavonol glycoside, quercetin-4'-O-beta -D-galactoside. The structures of the new compounds were established by conventional analytical methods and confirmed by spectral analyses. Two known flavonoids, luteolin-7-O-rhamnoside, luteolin-7-O-glucoside, and two known gallotannins, penta-O-galloyl-beta -D-glucose and 1,2,3,6-tetra-O-galloyl-beta -D-glucose were also isolated.
