Objective:
To study the chemical composition of the stems and leaves of Cassiafloribunda.Methods:
The chemical constituents from stems and leaves of C. floribunda were isolated by silica gel MCI, RP-18, TLC, and HPLC methods. Their structures were elucidated by spectroscopic methods and physicochemical properties.Results:
Eighteen compounds were isolated from the 90% EtOH extract of C. floribunda and their structures were established ascassia cis-transdiphenylpropanoid(1), ethyl p-hydroxycinnamate (2), shonanin(3), dibutyl phthalate(4), 1,6,8-trihydroxyl-3-methyl-anthraquinone (5), 2,5-dimethyl-7-hydroxyl-chromogen, (6), 2-(2'-hydroxypropyl)-5-methyl-7-hydroxytryptophan(7), 4',7-dihydroxy-5-methoxy flavone(8), chrysoeriol(9), kaempferol(10), apigenin(11), 3-methoxy quercetin(12), 6-demethoxycapillarisin(13), 7,4'-dihydroxyflavone(14), luteolin(15), butin(16), liquiritigenin(17) anderiodictyol(18).Conclusion:
Compound 1 is a new compound, and 2-18 are isolated from this plant for the first time.At the moment,2-4, 8, 9, 11, 13, 14, 16-18 are isolated from Cassia for the first time.
