- Abstract
- A new cyclic triterpene saponin, phyteujaposide (1) and eight known compounds (2-9) were isolated from the leaves of Phyteuma japonicum. The structure of the new compound (1) was elucidated by 1D and 2D data analysis, acid hydrolysis and GC-MS. Compounds 7 and 9 potently inhibited the NO production in LPS-activated BV-2 cells and compounds 5 and 6 showed a significant secretion induction of NGF in C6 glioma without cell toxicity.
