1H-NMR data were consistent with structures 5a~f, for example, the 1H-NMR spectrum for compound 5c exhibits three sharp singlets at 3.526, 3.734, 3.792 ppm, corresponding to the methoxy proton at ester group and to the methoxy proton at quinazoline ring and benzene ring, respectively.
It can be described as a three-dimensional, highly branched, polyphenolic substance consisting of an irregular array of variously bonded "hydroxyl" and "methoxy"-substituted phenyl propane units.
The [sup.1]H NMR spectrum of 3 displayed resonances for an aromatic proton [[[delta].sub.5]H 7.05 (1H, s, H-4)], two meta-coupled protons [5h 6.84 ([[delta].sub.H,] d, J = 2.0 Hz, H-5) and 7.03 (2H, d, J = 2.0 Hz, H-7)], an aromatic methyl [[[delta].sub.H] 2.28 (3H, s, 3-C[H.sub.3])], a methoxy group [[[delta].sub.H] 3.88 (3H, s, 6-OC[H.sub.3])], and a [beta]-anomeric proton of a sugar moiety [[[delta].sub.H] 5.12 (1H, d, J = 8.0 Hz, H-1').
Particularly, a chemical component was found in heartwood and root; namely, (3R)-2',3',7-trihydroxy-4'- methoxyisoflavanone (40) displayed a Pf value 3-fold higher than positive control BHT and [alpha]-tocopherol in both concentrations 0.02% and 0.04%, which might be reasonable from three adjacent, two hydroxyl, and one methoxy groups [19,20, 34].
University of Massachusetts scientists fabricated hydrogel microspheres by the electrostatic complexation of low methoxy pectin and caseinate by decreasing the solution pH from 7 to 4.5.
The methoxy groups at C-7 and C-ll of 11-O-methylWEL were located inside and outside the coumestan plane, respectively (Fig.

The signal due to methyl protons (ligand MPM) appeared as singlet at [delta] 2.37 and 2.44 ppm, whereas signal due to methoxy protons appeared as singlet in the range [delta] 4.01-4.03 ppm.
Addition of a methoxy group, in lieu of a hydroxyl group, to the terminal quinone of AQ resulted in an inhibitory anthraquinone, namely, 2MeO (Figure 2(c)).
