White to brown powder | [Uses]
Sennoside B is used in the inhibition of platelet driven growth factor (PDGF) used and may inhibit proliferative disease which depend upon the PDGF pathway. Laxative. | [Definition]
ChEBI: A member of the class of sennosides that is (9R,9'S)-9,9',10,10'-tetrahydro-9,9'-bianthracene-2,2'-dicarboxylic acid which is substituted by hydroxy groups at positions 4 and 4', by beta-D
glucopyranosyloxy groups at positions 5 and 5', and by oxo groups at positions 10 and 10'. | [storage]
Store at 2-8°C, protect from light | [Purification Methods]
Sennoside B forms yellow crystals from aqueous acetone or large volumes of H2O. [Stoll et al. Helv Chim Acta 32 1896 1900, Beilstein 17 III/IV 3402.] |
