In the carbon spectrum, there are a total of six carbon signals for the chemical shift namely 102.3, 101.5, 100.7 (double) and 100.1 (double), which are the first signal of carbon at the end of the sugar-based segments. Combined with six ends hydrogen signal from the H-NMR spectra, it was further determined that it was a six sugar-based compound. The chemical shift range from 65.4 to 76.4 was resulted from the chemical shift of non-ends carbon within non-sugar based segments. Besides, there were multiple overlapping carbon signals and the chemical shift signal of two methyl carbon at 17.7 and 17.8 was observed in the high-field region. Combined with the H-NMR results namely two chemical shifts of 1.05 (3H, d, J = 6.2 Hz), 1.24 (3H, d, J = 5.1 Hz), it was indicated that two rhamnose base were included in the compound of the six sugar ligands, and the two methyl groups belonged to rhamnose. Based on the carbon chemical shift value of these two methyl [4], it was induced that the other four glycosylation in such compound should be galactose.
