Chemical Constituents of Ethyl Acetate Fraction from Cynodon dactylon / 中国药学杂志

ABSTRACT

OBJECTIVE: To isolate and identify the 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: Fourteen compounds were isolated from C. dactylon and their structures were examined by physicochemical characteristics and spectral data and identified as vanillin (1), arctigenin (2), maltol (3), (+)-dehydrovomifoliol (4), (3R, 6R, 7E)-3-hydroxy-4, 7-megastigmadien-9-one (5), (-)-loliolide (6), zhebeiresinol (7), 1-indole-3-carboxaldehyde (8), ferulic acid (9), matairesinol (10), pinoresinol (11), ethyl caffeate (12), traxillagenin (13), and impecylenolide (14). CONCLUSION: Compounds 1-14 are isolated from C. dactylon for the first time.
