Abstract
- Myricaria laxiflora is an endangered evergreen shrub that is the only species in the genus Myricaria narrowly distributed in the Three Gorges region in China, which has a highly tolerant to waterlogging. The chemical investigation of M. laxiflora led to the isolation and the structural elucidation of nine compounds ( 1 – 9 ), including one new oleanane type triterpenoid, (5 R , 8 R , 9 R , 10 R , 13 S , 17 S , 18 S ) 25, 28-dihydroxy- D -friedoolean-14-en-3-one ( 2 ). Their chemical structures were unambiguously elucidated by analysis of NMR and high resolution ESI mass spectroscopic data as well as by comparison with literature data, with the structure of 1 supported by X-ray crystallography. All these compounds were reported for the first time in M. laxiflora. Besides, compounds 1 and 6 were not previously known in the genus Myricaria. Finally, compounds 1 – 9 were assumed to contribute to the survival of M. laxiflora under waterlogging stress by eliminating the reactive oxygen species (ROS).
