“…The other components were tentatively identified according to their MS fragmentation pattern, and also by studying their UV spectral characteristics and reported literatures. Accordingly, the peaks were ascribed to cytidine (1) [27,28], uracil (2) [29,30], guanosine (4) [31,32], adenine nucleoside (6) [17,18], syringoside (7) [33,34] (10) [35], isomucronulatol-7,2′-di-O-glucoside (11) [36], biochanin-7-glucoside (12) [37,38], 9,10-dimethoxypterocarpan-3-O-xylosylglucoside (15) [39], 9,10-dimethoxypterocarpan-3-O-β-D-glucoside (16) [39], isomucronulatol-7-O-glucoside (17) [36,40], astragaloside VI (1′) [26,39,41], astragaloside VII (2′) [26,39,41], and astragaloside II (4′) [39,[41][42][43]. However, they still need to be further confirmed with the reference compounds and structural analysis by nuclear magnetic resonance (NMR) method.…”
