Saponins and Other Constituents from the Leaves of Aralia elata

“…18) The fatty acid methyl ester was recrystallized from MeOH to give an amorphous white powder and then analyzed by GC-MS. 4 . The signal for the methoxy group was appeared at d 3.65 as a singlet.…”

“…Many saponins have been isolated from this plant, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and were reported to show anti-diabetic activity, 17) cytoprotective effect on CCl 4 -induced hepatic injury, 7) ethanol absorption inhibitory effect, 6,14) and hypoglycemic activity. [10][11][12] Recently, we reported the isolation and identification of various triterpenoid saponins including two new saponins, durupcosides A and B, 2,3) and a cerebroside, aralia cerebroside 18) from the root bark of this plant.…”

“…Six saponins (1)(2)(3)(4)(5)(6) and two lipids (7,8) were isolated by successive chromatography using silica and reverse-phase C 18 from the n-hexane fraction. Five known saponins and two lipids were identified as a-hederin (1), 20) collinsonidin (2), 21) 4) urtica ceramides (7) 23) and arisaema glyceride 3 (8), 24) respectively, by direct comparison of the spectral data with the published values.…”

Phytochemical and Biological Investigations on Cephalaria anatolica

“…The structures of the new triterpene glycosides were determined as 3-O-β-D-glucopyranosyl- (2). The known compounds were identified as davisianoside A (3), davisianoside B (4) [15], elmalienoside A (5), elmalienoside B (6) [8], macranthoside A (7) [16], macranthodin A (8), macranthodin B (9) [17], akebia saponin D (10), dipsacoside B (11) [18], 3-O-β-D-glucopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-Larabinopyranosyl hederagenin 28-O-β-D-glycopyranosyl ester (12) [19] and aristatoside A (13) [10]. The structures of these compounds were identified by chemical methods including acidic and alkaline hydrolysis, silylation and extensive spectroscopic analysis, along with 1D, 2D NMR and HRESIMS data.…”
