title: Structures of new sesquiterpenes from Curcuma comosa.
abstract: From the methanolic extract of the rhizomes of Curcuma comosa cultivated in Thailand, six new sesquiterpenes, (+)- and (-)-comosols (1, 2), comosones I (3), II (4), and III (5), and dimethoxycurcumenone (6), were isolated. Their structures were elucidated on the basis of chemical and physicochemical evidence.
