Alkaloid and sesquiterpenes from the root tuber of Curcuma longa.
One new quinoline alkaloid and seven known bisabolane sesquiterpenes: 2-(2'-methyl-1'-propenyl)-4, 6-dimethyl-7-hydroxyquinoline (1), 2, 5-dihydroxybisabola-3, 10-diene (2), 4, 5-dihydroxybisabola-2,10-diene (3), turmeronol A (4), bisacurone (5), bisacurone A (6), bisacurone B (7) , bisacurone C (8), as well as dehydrozingerone (9) and zingerone (10) were isolated from the root tuber of Curcuma longa. Their structures were identified by spectral evidence. Compound 1 is a new compound, compounds 6 -8 were isolated from this plant for the first time and compounds 9 - 10 from Curcuma for the first time.
