Abstract
Partial methanolysis of the mucilage from Ulva conglobata gave methyl α-l-rhamnoside (29.07%), methyl α-d-xyloside (7.04%) and methyl α-d-glucoside (5.13%). Separation of a new disaccharide (methyl α-l-rhamnobioside, 3.4%) from methanolysate was achieved chromatographically. The biose was attacked by maltase but not by emulsin. The results and infrared spectrum show that the rhamnobiose derivative consists of rhamnose units linked by α-link.This publication has 5 references indexed in Scilit:
