- Carbon-13 NMR spectra of tannins
- Carbon-13 NMR spectra of tannins. Tanning existing as equilibrium mixtures, and others. Yoshida, Takashi; Hatano, Tsutomu; Matsuda, Muneto; Okuda, Takuo; Shingu, Tetsuo (Fac. Pharm. Sci., Okayama Univ., Japan).Some commonly used reagents like 84744-51-4 and 79786-08-6 are used in this experiment. Tennen Yuki Kagobutsu Toronkai Koen Yoshishu, 27th, 718-25 (Japanese) 1985. CODEN: TYKYDS. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 26, 33 Two-dimensional (1H-1H and 1H-13C) NMR is used to assign the glucose 13C signals of the monomeric tannins tellimagrandin, pedunculagin, and gemin D. This anal. applied to the dimer rugosin E shows that the assigned signals are made up from the 2 monomeric precursors. The complicated 13C resonances of glucose moieties of dimers or trimers which exist as mixts. of 2-8 tautomers are assignable based on the data of the monomeric units. This approach is an adjunct to chem. degrdn. and has been applied to the oligomers camptothin A and B, and oenothein B which are isolated from C. acuminata and O. erythrosepala. The 13C chem. shifts of the 1C4 glucopyranose cores of geraniin, chebulagic acid, and corilagin and those of the open-chain glucose in the C-glucosidic illagitannins, casuarinin and consequent by stachyurin and casuariin are also assigned. .
