OBJECTIVE
To study the chemical constituents of the roasted seeds of Cassia obtusifolia, and to illuminate the change of its effective components before and after being roasted.
METHODS
The compounds were isolated and repeatedly purified by macroporous resin, silica gel column chromatography. Their
A novel naphthopyrone derivative, named quinquangulone (1), has been isolated from Cassia quinquangulata, along with the known compounds quinquangulin (2) and its two glycosides (3 and 4), rubrofusarin (5) and its two glycosides (6 and 7), nor-rubrofusarin (8) and its 6-O-glucoside (9), and three
Radical scavenging principles on 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical were isolated from the seeds of Cassia tora L. Assignments of the 1H- and 13C-NMR data showed the active components to be an anthraquinone, alaternin and two naphthopyrone glycosides,
Peroxynitrite (ONOO-), formed from the reaction of superoxide (.O2-) and nitric oxide (NO), is a potent oxidant that contributes to the oxidation of various cellular constituents, including lipids, amino acids, sulfhydryls and nucleotides. It can cause cellular injury, such as DNA fragmentation and
Thirteen phenolic glycosides including six new compounds were isolated from seeds of Cassia tora (Leguminosae). The structures of the new compounds, rubrofusarin triglucoside (7), nor-rubrofusarin gentiobioside (9), demethylflavasperone gentiobioside (10), torachrysone gentiobioside (11),
Cassia obtusifolia Linn. have been used to improve vision, inflammatory diseases, and as hepatoprotective agents and to promote urination from ancient times. In the present study, we investigated the influence of glycosylation of components of C. obtusifolia and structure-activity relationships
