A new angular furanocoumarin, 2′ acetylangelicin (8), along with oroselone (1), columbianadin (3), bergapten (4), O acetyl columbianetin (5), cniforin A (6), edultin (7) and β sitosterol (2), was isolated fro...A new angular furanocoumarin, 2′ acetylangelicin (8), along with oroselone (1), columbianadin (3), bergapten (4), O acetyl columbianetin (5), cniforin A (6), edultin (7) and β sitosterol (2), was isolated from the fruit of Cnidium monnieri. The structures were elucidated by spectral methods. Compound 1 was isolated from this plant for the first time.展开更多

Pulmonary inflammation was induced by intratracheal instillation of LPS and CSC five times within 12 days. CM extract was administered orally at a dose of 50 or 200 mg·kg-1. The number of inflammatory cells in the bronchoalveolar lavage fluid was counted using a fluorescence activated cell sorter. Inflammatory mediator levels were determined by enzyme-linked immunosorbent assay. The administration of LPS and CSC exacerbated airway hyper-responsiveness(AHR) and induced an accumulation of inflammatory cells and mediators, and led to histological changes. However, these responses are modulated by treatment with CM, and the treatment with CM extract produces similar or more extensive results than the treatment with cyclosporin A(CSA). CM extract may have an inhibitory effect on pulmonary inflammation related with chronic obstructive pulmonary disease.展开更多

Methods Qualitative analysis of coumarins in C. monnieri was detected by UHPLC-ESI-Q-TOF/MS. Quadrupole TOF/MS in either full scan mode or extracted ion mode was used for the qualitative analysis of the constituents. Relative peak area of each component was used for the hierarchical cluster analysis. Results According to UHPLC-ESI-QTOF-MS data, chemical structures of 28 coumarins in the fruits of C. monnieri were identified, including 19 simple coumarins, seven linear coumarins, and two angular coumarins. Among these constituents, ten coumarins were firstly identified in C. monnieri. In addition, hierarchical cluster analysis suggested that C. monnieri from different regions could be classified into four groups, and this clustering was correlated to the distribution significantly, Xuzhou could be regarded as the genuine producing area. Conclusion UHPLC-ESI-Q-TOF-MS is a viable method for qualitative analysis and quality evaluation of coumarins from the fruit of C. monnieri. Coumarins in C. monnieri exists intra-species variance, which indicates significant meaning for the quality control and choice of famous region drug for C. monnieri in the clinic medication.展开更多
