Glycosylation of phenolic compounds by root culture of Panax ginseng

Iridoid and phenolic diglycosides from Canthium berberidifolium

“…The chemical shifts of compound 7 coincided with those reported data for methyl 2-O-b-d-glucopyranosyl benzoate (Ushiyama and Furuya, 1989). However, additional signals of the apiofuranosyl unit were observed from the spectra of compound 7.…”

“…Seven were identified as known compounds: geniposidic acid (1) (Guarnaccia et al, 1972;Toda et al, 1985), 4-O-bd-glucopyranosylacetophenone (picein, 3) (Ushiyama and Furuya, 1989) (Wang et al, 1998) (Miyase et al, 1987), koaburaside (8) (Ogawa et al, 1973;Gewali et al, 1988) and hymexelsin (12) (Rao et al, 1988) by comparison of physical data with literature values and from spectroscopic evidence.…”

“…*p<0.05, **p<0.01 indicate statistically significant differences from control. (Pouchert and Behnke, 1993;Miyajima et al, 1971), naringenin (2) (Duddeck et al, 1978), aromadendrin (3) (Chang et al, 2004), (+)-catechin (4) (Morimoto et al, 1985), picein (5) (Whang et al, 1995;Ushiyama and Furuya, 1989), 1-p-coumaroyl-β-D-glucoside (7) (Kashiwada et al, 1984;Zhang et al, 2008), and dihydromyricetin (8) (Miller and Bohm, 1979). Compound 6 was trans-p-coumaryl glycoside according to the 1 H-and 13 C-NMR data.…”

New Iridoid Glucosides from the Aerial Parts of Verbena brasiliensis

“…The aqueous MeOH layer was successively subjected to Diaion HP20 and silica gel column chromatography as well as HPLC on ODS to afford 15 compounds (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Chromatography of the hexane layer over silica gel and Diaion HP20 furnished 16.…”
