J Asian Nat Prod Res. 2009;11(2):128-31. doi: 10.1080/10286020802573859.

Abstract

One new oleane-type triterpene saponin, named lysimachiagenoside A and the known 21-O-angeloylbarringtogenol C were isolated from the aerial parts of Lysimachia foenum-graecum Hance. 21-O-angeloylbarringtogenol C was a new natural product. These structures were identified on the basis of 1D- and 2D-NMR techniques, including 1H-1H COSY, HMQC, HMBC, TOCSY, and ROESY experiments as well as chemical methods.
