assignments should be reversed (for corrected carbon assignments, see Table 3). Additionally, the hellinoyl C-3′′ signal was not assigned in the previous report.7 Because the aromatic skeleton 13C NMR signals of 2 were not fully assigned and the 1H NMR signals were not shown in detail in the previous report,7 spectroscopic experiments including 1H and 13C NMR, 1H-1H COSY, HSQC, and HMBC (Figure 1) were performed, and the results are summarized in Table 3 (also see Experimental Section). Tamarixinin A (3) was isolated as a major tannin from the T. nilotica aqueous acetone extract. It was first isolated from T. pakistanica Quaiser.8 However, the 1H-1H COSY data obtained in our study revealed that the proton signals that were previously assigned to glucose-1 H-2-H-5 in the R-anomer should be interchanged with those assigned to the corresponding protons of the same glucose in the -anomer (for corrected proton assignments, see Table 1), and the assignment of the glucose-1 methylene proton with a higher-field shift should be revised to δH 3.78 (H-6R) and 3.88 (H-6). The total carbon assignments were also achieved on the basis of the NMR experiments similar to those applied for the hirtellin B carbon assignments. The detailed assignments of the aromatic protons of 3 are also shown in the Experimental Section. Structural Elucidation of Macrocyclic-Type Ellagitannins. Nilotinin D9 (10) was isolated as an off-white, amorphous powder. Its molecular formula, C68H50O44, was established by HRESIMS
