Abstract
A novel flavonoid C-glycoside, 5-hydroxy-7-methoxy-6-C-glycosylflavone (1), was isolated from the aerial part of Sphaeranthus indicus. Its structure was elucidated by spectroscopic methods.
Highlights
Sphaeranthus indicus L. is a multi-branched herb with round purple flowers that grows plentifully in rice fields [1, 2] and is distributed throughout India, Ceylon, Malay, China and Africa
Molecules 2007, 12 on the aerial parts of this plant revealed it to be quite rich in essential oils, glucosides and eudesmanoids [7], along with some uncharacterized sesquiterpenes, phenolic glycosides, and sesquiterpene lactones [8, 9]
In this paper we report the isolation and structure elucidation of 5-hydroxy-7-methoxy-6-C-glycosylflavone (1) from the aerial parts of the plant
Summary
Sphaeranthus indicus L. is a multi-branched herb with round purple flowers that grows plentifully in rice fields [1, 2] and is distributed throughout India, Ceylon, Malay, China and Africa.
