There are only minor differences in NMR chemical shift among glucosyl glycine esters 15-18.  Similar patterns were followed for glucosyl valine ethers 19-22. Take compound 19 as an example, the amide proton exhibited a chemical shift at around 8.21-8.23 ppm as a triplet. The 1H-NMR chemical shifts for hydroxyl groups linked to C2, C3, C4 and C6 were located at 5.10-5.11 ppm, 5.00-5.02 ppm, 5.26-5.27 ppm as doublets and 4.60-4.62 ppm as triplets, respectively. The 1H-NMR chemical shift of protons linked to C1, C2, C3, C4, C5, and C6 of the glucosyl ring were at 5.34-5.35 ppm as doublets, and 3.65–3.62, 3.47–3.42, 3.25–3.23, 3.22–3.19, 3.14–3.10 ppm of multiple-peaks. The chemical shift for CH2 groups on fatty chains were mainly located between 0.83 ppm to 2.14 ppm.
