Petroleum extracts of Cynanchum cutum L. and structure elucidation of isolated compounds

Abstract

In present study, petroleum ether extracts of Cynanchum cutum L. isolated unknown active constituents and their structure elucidated by analytical technique. The extracts were analyzed by the GC/MS technique. The GC chromatogram showed nine peaks corresponding to four compounds. These four compounds were identified on the basis of a high percentage of matching with authentic spectrum using NIST library.
