从地钱（Marchantia polymorpha，M.古珊瑚变种diptera和M.（地钱目）。多裂轮叶藓（Riccardia multifida）（Metzgeriales）也含有两个新的环状联苄，即轮叶藓素A和轮叶藓素B，它们分别含有一个醚和一个联苯键。环状bisbibenzyls的存在下，没有被证实在Dumortiera hirsuta和Preissia quadrata（地钱目）。现有的化学数据支持D.通过黄酮类化合物化学分析，多毛地钱和方地钱与地钱并不紧密相关，而地钱目的一些物种与梅茨geriales的物种有密切的亲缘关系。
Marchantins A, B and C, 3 new cyclic bisbibenzyls with 2 ether links were isolated from the liverworts Marchantia polymorpha, M. paleacea var. diptera and M. tosana (Marchantiales). Riccardia multifida (Metzgeriales) also contained 2 new cyclic bisbibenzyls, riccardins A and B, with an ether and a biphenyl link. The presence of cyclic bisbibenzyls was not confirmed in Dumortiera hirsuta and Preissia quadrata (Marchantiales). The present chemical data support that D. hirsuta and P. quadrata are not closely allied to Marchantia by flavonoid chemistry and some species of Marchantiales have close affinities to those of Metzgeriales.
