A sesquiterpenoid with plant growth regulatory activity fromSaussurea lappa
摘要:
Saussureal, a sesquiterpenoid with a new type of modified eudesmane skeleton has been isolated from roots of Saussurea lappa. In saussureal, ring A is five-membered and displays significant biological activity as a plant growth regulator. Its structure has been elucidated on the basis of spectral data and chemical correlation with alpha-santenolide.
