  • Title: Polyphenols from Cornulaca monacantha.
    Author: Kandil FE, Grace MH.
    Journal: Phytochemistry; 2001 Oct; 58(4):611-3. PubMed ID: 11576609.
    Abstract:
    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.
