Objective To separate and identify chemical constituents from Cynodon dactylon. Methods The chemical constituents of the alcohol extract of C. dactylon were isolated and purified by various chromatography methods, and their structures were identified by physical and chemical properties and spectral data. Results Twelve compounds were separated from C. dactylon and their structures were examined by physicochemical characters and spectral data and identified as leachianol G (1), leachianol F (2), parthenostilbenin B (3), parthenostilbenin A (4), restrytisol B (5), caraphenol C (6), pallidol (7), laetevirenol A (8), quadrangularin B (9), quadrangularin C (10), quadrangularin A (11), and parthenocissine A (12). Conclusion Compounds 1-12 are isolated from C. dactylon for the first time.
