“…The structural information obtained from the 66 UV spectra (Supplementary Fig. S1) suggested that 19 (1, 3-8, 18, 20, 22, 23, 26, 27, 32, 33, 35, 37, 43, 55) were phenolic acids, 18 (2, 9-11, 13, 15, 16, 21, 29, 34, 40, 50, 51, 57, 59, 60, 63, 64) were isoflavones, three (12,14,47) were flavones, and two (19,24) were dihydroflavonoids. Besides, 18 flavonol glycosides were found, distributed as one myricetin-3-O-glycoside (25), nine kaempferol-3-Oglycosides (28,41,42,44,46,48,53,54,56), three quercetin-3-O-glycosides (31,39,45), one kaempferol-3,7-Odiglycoside (52), and four flavonol glycosides to which a type could not be assigned (17,30,36,49).…”
