Abstract

Comparison of the methanolic extracts from leaves, stems, and rhizomes of Menyanthes trifoliata L. by TLC showed that the main compounds are dihydrofoliamenthin, menthiafolin, and loganin, whereas foliamenthin was lacking. The monoterpene carboxylic acid of dihydrofoliamenthin was determined to be a derivative of nerol and the configuration of carbon 7 of the secoiridoid skeleton was shown to be β by spectroscopic evidences.
