Two New Trijugin-Type Limonoids from Cipadessa cinerascens

摘要

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.
