Study on Chemical Constituents of Dichrocephala integrifolia

Objective: Study on the chemical constituents of Dichrocephala integrifolia. Method: The constituents were isolated and purified by silica gel column and Sephadex LH-20 chromatography and their structures were elucidated by spectral analysis and physicochemical properties. Result: Sven compounds were obtained and identified as docosane (1), N-octacosanoic acid (2), eicosanoic acid (3), henicosanoic acid methyl ester (4), methyl phaeophorbide-a (5), pectolinarigenin (6) and pectolinarigenin-7-glucoside(7). Conclusion: All these compounds were obtained from this plant for the first time.
