neo-Clerodane diterpenoids from Scutellaria galericulata

2016 China Journal of Chinese Materia Medica  
Four neo-clerodane diterpenoids, neoajugapyrin A, scutegalerins A and B and scutecolumnin C have been isolated from the acetone extract of the aerial parts of Scutellaria galericulata. Neoajugapyrin A and scutecolumnin C are reported in this species for the first time, whereas scutegalerins A and B are new compounds. NMR data of neoajugapyrin A are discussed in detail to support the proposed revised structure of ajugapyrin A.
