Abstract Two new trijugin‐type limonoids, cipatrijugins G and H ( 1 and 2 , resp.) along with four known limonoids, were isolated from the leaves of Cipadessa cinerascens. All structures were elucidated on the basis of spectroscopic analyses, including IR, 1D‐ and 2D‐NMR, and ESI‐MS and HR‐ESI‐MS techniques.
