“…On the basis of above discussion and combined NMR and mass data, the structure of compound 1 was established to be 2-bromodimethylbenzene-1,4-dioate. To the best of our knowledge, both compounds 1 and 2 have not been described earlier as natural products, while compound 2 has been synthesized previously by many researchers [31][32][33] The structures of the known compounds ( Figure 1) were determined as fucosterol (3) [34][35][36], nhexadecanoic acid, methyl ester (4) [37,38], ꞵ-sitosterol (5) [35,39], cerotic acid (6) [40,41], n-octacos-9enoic acid (7) [42,43], and 11-eicosenoic acid (8) [44,45], on the basis of their spectral data and the comparison of their spectral data with those reported in literature. Compound 2 was obtained as a colorless amorphous powder with the molecular formula C 12 H 13 BrO 4 , deduced from the HR-ESI-MS and 13 C-NMR data ( Figure 1).…”
