Objective: To isolate and identify the chemical constituents of the bermudagrass and two stems. Methods: Various chromatographic techniques were used for the separation and identification of structures based on physicochemical properties and spectroscopic methods. Results: Six compounds were isolated, bis (2,3-dihydroxypropyl) octacosanedioate (1), tetratriacontanol (2), palmitic acid Glycerol monopalmitate (4), β-sitosterol (5) and daucosterol (6). Conclusion: Compound 1 is a new compound, and compounds 2 ~ 4 are isolated from this genus for the first time.
