Phenolic compounds of Abies nephrolepis and their NO production inhibitory activities.

Two new, i.e., 1 and 2, and 69 known phenolics were isolated from the aerial parts of Abies nephrolepis.

Sesquiterpenoids from Inula lineariifolia inhibit nitric oxide production.

Fourteen sesquiterpenoids including six new analogues (1-6) were isolated from the aerial parts of Inula lineariifolia.. The structures of the new sesquiterpenoids were determined by spectroscopic data analysis, and the structures of 1 and 6 were confirmed by single-crystal X-ray diffraction data and the modified Mosher method.
