Toonamicrocarpavarin, a new tirucallane-type triterpenoid from Toona Ciliata
Abstract
Toonamicrocarpavarin (1), a new tirucallane-type triterpenoid, along with eight known ones, piscidinol A (2), toonaciliatavarin E (3), toonayunnanin A (4), 7-acetyneotrichilenone (5), hispidol A (6), odoratone (7), phellochin (8), toonaciliatavarin D (9), were isolated from T. ciliata. Their structures were identified on the basis of ESIMS, HREIMS and 1 D/2D NMR analysis. The cytotoxic activity of the new compound was also evaluated. All compounds were obtained from T. ciliata for the first time, which plays an important role in chemotaxonomy of the plant T. ciliata.
Keywords: Toona ciliata; cytotoxic activity; toonamicrocarpavarin; triterpenoid.
