木贼以两种化学型存在，一种出现在亚洲和北美，另一种出现在欧洲。来自亚洲和北美的贫瘠芽菜含有黄酮 5-葡萄糖苷及其丙二酰酯，而欧洲材料不含这些化合物。两种类型均含有槲皮素 3-O-.β.-D-吡喃葡萄糖苷及其丙二酰酯。槲皮素 3-O-槐糖苷、芫花素 4''-O-.β.-D-吡喃葡萄糖苷和原花素 4''-O-.β.-D-吡喃葡萄糖苷仅在欧洲材料中发现。所有新化合物的结构均已得到证实。
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 ad their malonyl esters, whereas European material is free from these compounds. Both types contain quercetin 3-O-.beta.-D-glucopyranoside, and its malonyl ester. Quercetin 3-O-sophoroside, genkwanin 4''-O-.beta.-D-glucopyranoside and protogenkwanin 4''-O-.beta.-D-glucopyranoside are only found in European material. The structures of all new compounds are proven.
