- 中文摘要: Two new tetracyclic triterpenoids shiona-19(E),21-dien-3β-ol (1), and shiona-22(29)-en-3β,21-diol (2), together with four known compounds shiona-21-en-3β-ol (3), friedelinol (4), β-sitosterol (5), and (24R)-stigmast-7,22(E)-dien-3α-ol (6) were isolated from Aster ageratoides var. oophyllus. The structures of two new compounds were established on the basis of IR, MS, 1H, 13C and 2D NMR spectroscopic methods.
