Abstract

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. Highlights: A phytochemical investigation on the fruits of Amomum kravanh was conducted. Thirteen compounds including a new secolignan were isolated and structurally characterized. The chemotaxonomic significance of the isolated compounds was discussed.
