Gum exudates from nine specimens of Laguncularia racemosa (Combretacea
e) from Venezuela were examined. The constituent sugars found were gal
actose, arabinose, rhamnose, galacturonic acid, glucuronic acid and it
s 4-O-methyl ether. The results obtained are similar to those in many
Combretum gums studied; giving acidic solutions, their nitrogen conten
t tends to be low and their rhamnose content, after acidic hydrolysis,
tends to be high. The gum, in deuterium oxide, shows a well resolved
(CNMR)-C-13 spectrum.
