Abstract

Notopterygium incisum (QH) has been used for the treatment of rheumatoid arthritis (RA), and volatile oils may be its mainly bioactive constituents. The present study was designed to analyze the volatile compounds in QH and to determine the anti-arthritic capacity of Notopterygium volatile oils and the potential mechanism of action. The volatile compounds analysis was conducted by GC-MS. The anti-arthritic capacity test of the volatile oils was conducted on adjuvant-induced arthritis (AIA) rats. The anti-inflammatory property was tested in NO release model in RAW 264.7 cells. Endothelial cells were used to evaluate the anti-proliferative and anti-tube formative effects. 70 compounds were analyzed by GC-MS in the volatile oils. Notopterygium volatile oils weakened the rat AIA in a dose-dependent manner (2, 4, and 8 g crude drug/kg). The NO production by RAW 264.7 was decreased by more than 50% in Notopterygium volatile oils (5, 15, and 45 μg·mL-1) pretreated groups. Notopterygium volatile oils also inhibited EAhy926 cell proliferation and further delayed EAhy926 cell capillary tube formation in a concentration-dependent manner. The anti-NO productive, anti-proliferative, and anti-tube formative effects of Notopterygium volatile oils strongly suggested that the therapeutic effect of QH in AIA might be related to the potent anti-inflammatory and anti-angiogenic capacities of the volatile oils.
