Abstract
Analytical data are presented for eight gum specimens from Pereskia gu amacho (Cactaceae). They are dextrorotatory acidic arabinogalactans an d give very clear solutions of moderate viscosity. The gum contains ga lacturonic acid, glucuronic acid and its 4-O-methyl ether, galactose, arabinose, xylose and rhamnose. C-13-NMR spectrum of degraded gum A of P. guamacho shows interesting structural features of the gum studied.
