Caracterización de la composición de carbohidratos en extractos acuosos de la corteza de mangle rojo (Rhizophora mangle L.)

Red mangrove (Rhizophora mangle L.) is widely used in herbal medicine due toits numerous pharmacological properties, primarily attributed to its high content ofphenolic compounds. These compounds provide antioxidant, antimicrobial,antimutagenic, cytotoxic, and antiulcer properties. The composition ofcarbohydrates in the aqueous extract of red mangrove bark (R. mangle) wascharacterized using trimethylsilyl (TMS) derivatives of carbohydrates andconfirmed with alditol acetate (AA) derivatives. Total sugars in the freeze-driedproduct represented 17.5%, with the major component accounting for 14.8%, andcarbohydrate structures representing only 2.7%. The carbohydrate composition ofR. mangle bark included rhamnose, arabinose, xylose, and fucose (56.94%,13.33%, 12.62%, and 12.35%, respectively) and ribose (4.75%). Bothderivatization methods revealed the presence of a major non-carbohydriccompound, possibly a polyphenol co-extracted and analyzed with thecarbohydrates.
