Chemical constituents from the fruits of Amomum kravanh

Abstract

Chemical investigation of the traditional Chinese medicine Amomum kravanh led to the isolation of a new secolignan (1), two flavonoids (2 and 3), four monoterpenoids (4–7) and six steroids (8–13). Compounds 1, 5–8 and 12–13 were isolated from the family Zingiberaceae for the first time. Compound 1 is the first lignan reported in the genus Amomum and compound 8 is firstly described as a natural product, which could be of chemotaxonomic importance for the genus Amomum and family Zingiberaceae.
