Three known bisabolane hydrocarbons, a-trans -bergamotene, sesquiphellandrene and zingiberene, were isolated from the aerial parts of Alpinia densibracteata . Their 1H and 13C NMR spectra were completely assigned by using a combination of 13C DEPT and 2D-NMR experiments (1H-1H COSY, single-bond 13C-

High-resolution solid-state 13C-nmr spectra of ( 1 + 3 ) -P-D-xylan from Bryopsis maxima and Caulerpa brachypus were recorded for various preparations from intact through dried frond to anhydrous and hydrated xylan, to gain insight into their secondary structures as compared with those of ( 1 + 3) -
On the basis of C-H correlation experiments, COSY, and other 2-dimensional nmr evidence, the 'H and 13C-nmr assignments for securinine are revised from those previously proposed. Assignments are also made for the biologically relevant hydrochloride salt of securinine in D20. The spectra of allosecur
## Abstract The ^1^H, ^13^C and ^15^N NMR studies have shown that the __E__ and __Z__ isomers of pyrroleβ2βcarbaldehyde oxime adopt preferable conformation with the __syn__ orientation of the oxime group with respect to the pyrrole ring. The __syn__ conformation of __E__ and __Z__ isomers of pyrrol
