“…The EtOAc extract was further isolated by various CC on Diaion HP20SS, RP-18, Toyopearl HW-40F, MCI-gel CHP20P, and Sephadex LH-20, to yield 32 compounds, including one undescribed hydrolyzable tannin ( 1 ) and one new natural product ( 24 ). The compounds, which had were in advance, were recognized as seven hydrolyzable tannins ( 2 − 8 ) including 4- O -(6′- O -galloyl- β -D-glucopyranosyl)- cis - p -coumaric acid ( 2 ) [ 21 ], 2- O -galloyl-4,6- O -( S )-hexahydroxydiphenoyl- β -D-glucopyranose ( 3 ) [ 22 ], 1- O -galloyl-4,6- O -( S )-hexahydroxydiphenoyl- β -D-glucopyranose ( 4 ) [ 23 ], 1,2-di- O -galloyl-4,6- O -( S )-hexahydroxydiphenoyl- β -D-glucopyranose ( 5 ) [ 24 ], 1,6-di- O -galloyl- β -D-glucopyranose ( 6 ) [ 25 ], 1,2,6-tri- O -galloy- β -D-glucopyranose ( 7 ) [ 26 ], and 1,4,6-tri- O -galloyl- β -D-glucopyranose ( 8 ) [ 27 ], 10 flavonol and its glycosides ( 9 − 18 ) including kaempferol 3- O - β -D-glucopyranoside ( 9 ) [ 28 ], kaempferol 3- O -(6″- trans - p -coumaroyl)- β -D-glucopyranoside ( 10 ) [ 29 ], quercetin 3- O - β -D-glucopyranoside ( 11 ) [ 30 ], kaempferol 3- O -rutinoside ( 12 ) [ 23 ], rutin ( 13 ) [ 31 ], kaempferol 3- O - β -D-galactopyranoside ( 14 ) [ 32 ], kaempferol 3- O - α -L-rhamnopyranoside ( 15 ) [ 33 ], quercetin ( 16 ) [ 34 ], quercetin 3-(2″- β -D-glucosyl)- α -L-rhamnopyranoside ( 17 ) [ 35 ], and kaempferol 3-(2″- β -D-glucosyl)- α -L-rhamnopyranoside ( 18 ) [ 35 ], and 14 simple phenolics ( 19 − 32 ) including gallic acid ( 19 ) [ 36 ], 3,4-dihydroxybenzoic acid ( 20 ) [ 37 ], p -hydroxybenzoic acid ( 21 ) [ 38 ], m -hydroxybenzoic acid ( 22 ) [ 39 ], methyl gallate ( 23 ) […”
