摘要：

Equisetum arvense exists as two chemotypes one occurring in Asia and North America and the other in Europe. Barren sprouts from Asia and North America contain flavone 5-glucosides and their malonyl esters, whereas European material is free from these compounds. Both types contain quercetin 3-O-β-d-glucopyranoside, and its malonyl ester. Quercetin 3-O-sophoroside, genkwanin 4′-O-β-d-glucopyranoside and protogenkwanin 4′-O-β-d-glucopyranoside are only found in European material. The structures of all new compounds are proven. © 1990.
