Abstract:
The present paper deals mainly with the chemical contents of the family Equ-
isetaceae in China. The taxonomic value of the flavonol in this family is discussed.
The results of chemical investigation show that kaempferol-3,7-diglucoside and kaempfe-
rol are the characteristic components of the family; kaempferol-3-diglucoside is characteristic of
the genus Hippochaete and quercetin is characteristic of the genus Equisetum.
Described in this paper are isolation of 11 compounds and identification of 7 compounds
in this experiment, among which kaempferol-3-diglucoside and succinic acid are isolated from
Hippochaete hiemale for the first time.
