Abstract

Abstract: In this paper, 2D long-range ¹³C-¹H heteionuctear chemical shift correlation spectroscopy, in combination with ¹³C-¹H heteronuclear chemical shift spectroscopy and ¹H-¹H homonuclear chemical shift spectroscopy, have been used to elucidate the structure of an ocotillol-type saponin (OTS) which was first separated from the leaves of Panax Quinquefolium L., and the results were also confirmed by element analysis and FAB-MS techniques.

Key words: Structure elucidation, Ocotillol-type saponin (OTS), 2D-NMR, Leaves of Panax Quinquefolium L
