MedKoo CAT#: 581207

CAS#: 256459-34-4

Description: Dactylorhin A is one of the group of important active constituents in the mature tubers of orchidaceae. Five new compounds known as dactylorhin A-E and two natural ocmpounds known as dactyloses A-B have been reported from the roots of the plant. Dactydactylorhin A and dactylorhin E in enzymatic hydrolysis using almond emulsion give dactylorhin C. Also, dactylorhin D and dactylorhin B in enzymatic hydrolysis using cellulose give a 7a compound butanedioic acid, which in hydrolysis gives Loroglossin.
