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.

Key words: Equisetaceae, Equisetum, Hippochaete, kaempferol-3, 7-diglucoside, kaempfe-
