Lignan and phenylpropanoid glycosides from Osmanthus asiaticus

Plant Polyphenols: Extraction, Structural Characterization, Hemisynthesis and Antioxidant Properties

“…The structure of compound 1, was completely elucidated and was identified as syringin through 1D and 2D NMR analysis. Its spectral data were in agreement with those previously reported in the literature for the same compound (Sugiyama et al, 1993).…”

Iridoid and megastigmane glycosides from Phlomis aurea

“…It is noteworthy that this compound was isolated and identi®ed by our group from the titled plant as well as by Sudo et al at the same time from Premna subscandens as a new natural product (Sudo et al, 2000). Compounds 5±15 were identi®ed as follows: compound (5) auroside (C Ë alis et al, 1991), compound (6) lamiide (El-Naggar and Beal, 1980), compound (7) 8-epiloganin (Bianco and Passacantilli, 1981), compound (8) ipolamiide (Saracoglu et al, 1995), compound (9) syringin (Sugiyama et al, 1993), compound (10) (11) acteoside (Saracoglu et al, 1995), compound (12) chrysoeriol-7-O-b-glucopyranoside (Tomas et al, 1986), compound (13) acacetin-7-O-b-glucopyranoside (Harborne and Mabry, 1982), compound (14) luteolin-7-O-b-glucopyranoside (ElNegoumy et al, 1986) and compound (15) liriodendrin (Kamel et al, 1992). ow rate of mobile phase 6 ml/min, injection vol.…”

Identification of Glucosyltransferase Genes Involved in Sinapate Metabolism and Lignin Synthesis in Arabidopsis

“…3B, this product is also stable in 1 N NaOH. The identities of the three glucose conjugates were further confirmed by NMR analysis (Table I) using NMR spectra assigned according to published information (24,25).…”
