Hepaticae produce some characteristic compounds as major components: among them, terpenoids are very significant chemosystematic markers at different taxonomic levels. From the chemical evidence, the following results have been obtained: 1) the chemical constitution of Hepaticae is clearly different from that of Musci. 2) Metzgeriales were possibly originated from the same ancestor as Jungermanniales. The Marchantiales belong to another evolutionary line. 3) Anthocerotae are more related to Hepaticae than to Musci. 4) Radulaceae and Plagiochilaceae each have isolated chemical characteristics. 5) Ptilidiaceae, Trichocoleaceae and Porellaceae seem to have some affinities to each other in chemical components. 6) There seems to be no chemical affinity between Porellaceae and Frullaniaceae, but some species of Porellaceae are similar to some genera of Lejeuneaceae. 7) In Metzgeriales, Blasiaceae and Metzgeriaceae each have isolated chemical characters. 8) In Marchantiales, Ricciaceae is a very isolated family in chemical components. Conocepahlum supradecompositum seems to be a more primitive species than Wiesnerella denudata and C. conicum from the chemical point of view.
