Three new steroids (1-3) and 13 reported analogs (4-16) were extracted from Datura metel L. pericarps. Structure analysis of these extracted compounds was performed by 1 D-NMR and 2 D-NMR spectroscopy, and their spectra were compared with those of similar compounds previously described in the literature. The extracted steroids (1-3) and known compounds (4-16) were evaluated for anti-inflammatory activity against LPS-activated RAW 264.7 cells. Compounds 5, 7, 9, 12 and 15 showed potential anti-inflammatory activity with IC50 less than 35 μM, while compounds 3 and 11 showed weak anti-inflammatory activity with IC50 less than 100 μM.
