Objective To study the chemical constituents from Fritillaria pallidiflora. Methods The constituents were isolated from F. pallidiflora and purified by column chromatography, and the structures were identified by spectra analysis and chemical methods. Results Sixteen compounds were isolated from F. pallidiflora, including phenolic acids, esters, alkaloids, and the structures were identified as 1,4-diphenylbutane (1), cis-cinnamic acid (2), 4-hydroxy-3-methoxybenzaldehyde (3), acetovanillone (4), 9-octadecenoicacidmethylester (5), methyl ferulate (6), 1-O-feruloylglycerol (7), trans-isoferulic acid (8), syringaresinol (9), pinoresinol (10), 2,3-O-diferuloylglycerol (11), 1,3-O-diferuloyl-glycerol (12), cyclo (L-Pro-L-Ala) (13), cyclo (L-Leu-L-Val) (14), bis (diethylene glycol)phthalate (15), and cyclo-(Phe-Val) (16). Conclusion All compounds are isolated from F. pallidiflora for the first time, and componds 1, 3-8, 10-13, 15, and 16 are isolated from the genus of Fritillaria for the first time.
