“…The structures of isolated compounds were characterized using various spectroscopic techniques, such as high-resolution electrospray ionization mass spectroscopy (HRESIMS), nuclear magnetic resonance (NMR), and so on. These isolated compounds were determined as glutinol (1) [13], friedelin (2) [14], betulin (3) [15], 2α,19α-dihydroxyursolic acid (4) [16], 2α-hydroxyursolic acid (5) [17], 1-hentriacontanol (6) [18], confusoside (7) [19], 2 ,3,4,4 -tetrahydroxydihydrochalcone (8) [20], 2 ,4,4 -trihydroxydihydrochalcone (9) [21], fragranone C (10) [22], 1-[4-(β-D-glucopyranosyloxy)-2-hydroxyphenyl]-3-(4-hydroxy-3-methoxyphenyl)-1-propanone (11) [9], butein-4 -O-β-Dglucoside (12) [23], kaempferol 6-C-β-D-glucopyranoside (13) [24], quercetin-3-Orhamnopyranoside ( 14) [25], quercetin-3-O-β-D-galactoside (15) [26], sulfuretin (16) [27], paeonoside (17) [28], and acernikol (18) [29]. According to the structural skeletons, the isolated compounds could be classified as triterpenoids (1)(2)(3)(4)(5), aliphatic alcohol (6), dihydrochalcones (7)(8)(9)(10)(11), chalcone (12), flavanols (13)(14)(15), aurone (16), phenolic glycosi...…”
