“…it is observed a hydrogen bonded to a formyl group (δ 10,63) bonded to quaternary carbon, (Figure 3). The NMR 13 C spectrum showed signals for six quaternary carbons (δ 43, 21,147,14,52,03,47,35,49,72,133,66), ten methyl carbons (δ 77,07, 125,75, 67, 17,52,10,38,29,52,71,34,12,77,07,130,58), where among them is the aldehyde carbon in δ 209,27; seven methylene carbons (δ 23,20,29,26,24,14,31,07,36,38,31,38,31,34,45,2). It was observed the presence of carbons related to the β-Glucopyranosyl group (δ 105,62, 76,65, 80,37, 73,31, 79,70), (Figure 4).…”
