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
