Spectral analysis of aegelin isolated from maja leaves (Aegle marmelos Corr.)
Abstract
the two dimension nmr spectrum (HMQC). The two protons are magnetic unequivalent which cause their chemical shifts are different. The protons appear as two doublet with different J value because its couple to a proton attached at the chiral carbon atom and the spin-spin splitting is observed. The existence of the two pairs of the doublets at d 3.67 d,J=3.4 Hz and d 3.42 d,J=8.5 Hz because the isolated aegelin from E.marmelos leaves contains of its enantimeer.
Key words: E. marmelos, aegelin, enantiomeer, spectroscopy
