Dichromate oxidation of sample SI caused an increase of the relative contribution of aromatic C (sum of aromatic C-H and aromatic C-O-R) (from 17% in NO-1 to 25% in CR-1) with a concomitant depletion of methoxyl C/Al-alkyl C and O-alkyl C (see Table 3).

In this research, acidified milk preblend (AMP) systems containing five ratios of carboxymethyl cellulose (CMC) to high methoxyl pectin were evaluated for their viscosity, pH, color and particle size.
The fluorescent color that appears under the UV light is affected by the negative charge on the sulfate group for cellulose sulfate or, for methyl cellulose, by the lone pair of electrons on the methoxyl group.
This paper examines the effects of phenolic and methoxyl substituents at the 6- and 7- positions of the 1,2,3,4-tetrahydroisoquinoline molecule on HPLC resolution of the above stereoisomers.
