Senna

Sennoside A is a member of the class of sennosides that is rel-(9R,9'R)-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'. The exact stereochemisty at positions 9 and 9' is not known - it may be R,R (as shown) or S,S. It is an oxo dicarboxylic acid and a member of sennosides. — ChEBI
