ETHNOPHARMACOLOGICAL RELEVANCE The heartwood of Caesalpinia sappan L. (Leguminosae), a widely used Chinese medicine in folk, has been used for the treatment of traumatic injury, stasis pain, amenorrhea, dysmenorrheal, as well as stabbing pain in the chest, abdomen and so on. Protosappanin B and brazilin, as the major bioactive homoisoflavones of Sappan Lignum, are used as the marker components ...
We performed an in vitro assay for seven compounds from methanolic extract of Sappan Lignum (CSE) that inhibit the chemical mediators of inflammation using the J774.1 cell line: brazilin (1), sappanchalcone (2), protosappanin A (3), protosappanin B (4), protosappanin C (5), protosappanin D (6), and protosappanin E (7). Those compounds were evaluated for their inhibitory effects on nitric oxide ...
3'-Deoxy-4-O-methylepisappanol, a new 3-benzylchroman derivative, was isolated from Sappan Lignum, together with thirteen known chemical compounds identified as protosappanin A, sappanchalcone, sappanone B, palmitic acid, (+)-(8S,8'S)-bisdihydrosiringenin, brazilein, 3-deoxysappanchalcone, (+)-lyoniresinol, 3-deoxysappanone B, protosappanin B, isoprotosappanin B, 3'-O-methylbrazilin and brazili...
The conditions of heating, ionic liquid-based ultrasonic-assisted extraction combined with reverse-phase high performance liquid chromatography were optimized to simultaneously isolate and determinate brazilin and protosappanin B in Caesalpinia sappan. Ionic liquids, including [BMIM]Br, [BMIM]BF4, [BMIM]PF6 and [HMIM]PF6, were selected as extraction solvents while methanol, acetone, acetonitril...
Protosappanin A (PrA), an immunosuppressive ingredient of the medicinal herb Caesalpinia sappan L, prolongs heart allograft survival in rats, possibly by impairing the function of antigen-presenting cells (APCs). We examined the effects of PrA on the maturation and function of dendritic cells (DCs), a potent class of APCs, and the downstream cell-cell and intracellular signaling pathways mediat...
oxidation of xanthine and hypoxanthine into uric acid, and plays a vital role in producing hyperuricemia and gout. Allopurinol is a clinically used XO inhibitor in the treatment of gout, which blocks the terminal step in uric acid biosynthesis can lower the plasma uric acid concentration. However, due to unwanted side effects of allopurinol, such as hepatitis, nephropathy, and allergic reaction...
