“…Compounds 3-4 have a -CH2-CH2-unit confirming by signals at 2.96 (2H), 4.06/3.79 (2H) for 3 and 2.94 (2H), 4.08/3.78 (2H) for 4, while compound 5 has only a -CH2-unit at 4.89 (1H, d, J = 12.0 Hz, Ha-7), 4.67 (1H, d, J = 12.0 Hz, Hb-7). So that, the NMR data of 3-5 were compared with the corresponding data, reported for 2-phenylethyl β-rutinoside, [12] 2phenylethyl β-primeveroside, [12] hydrangeifolin, [13] respectively, and found to match well. Compounds 6-8 were identified as tortoside A [14] , pinoresinol-4ʹʹ-Oβ-D-glucopyranoside [15] , icariside B2 [16] by comparing their NMR data with the corresponding reported data and further confirmed by the ESI-MS, HSQC and HMBC spectra.…”
