Identification of Narciclasine as an in Vitro Anti-Inflammatory Component of Cyrtanthus contractus by Correlation-Based Metabolomics

J Nat Prod. 2019 May 24;82(5):1372-1376. doi: 10.1021/acs.jnatprod.8b00973. Epub 2019 Apr 1.

Abstract

In this study, an extract from the bulbs of Cyrtanthus contractus showed strong anti-inflammatory activity in vitro. The extract was partially separated into 14 fractions and analyzed by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry metabolomics, and the correlation coefficients were calculated between biological activities and metabolite levels. As a result, the top-scoring metabolite narciclasine (1) is proposed as the active principle of C. contractus. This was confirmed by comparing the biological effect of crude extract with that of an authentic standard.
