Nine collections of this liverwort including fo. japonica (3), fo. fragilis. (5) and fo. robusta (1) were made in various parts of western Japan. The extracts obtained from them with methanol were analyzed through gas chromatography and mass spectroscopy to determine relative contents of four main sepquiterpenoids: β-pompene, maalioxide, bicyclohumulenone and cyclocolorenone. From the results (Table), an obvious difference of these phenotypes was recognized: 1) Totals of the four compounds were 85-96% of total sesquiterpenoid content for fo. japonica, 56-62% of total for fo. fragilis and 19% of total for fo. robusta. 2) Fo. jaonica contained all four sesquiterpenoids, of which maalioxide was predominant, while the other three were quantitatively comparable to each other in their presence. Fo. fragilis contained three sesquiterpenoids other than cyclocolorenone, of which β-pompene was prodominant, while the relative abundance of maalioxide and bicyclohumulenone decreased in that oder. Finally, fo. robusta lacked bicyclohumulenone and cyclocolorenone and contained about 10% each of β-pompene and maalioxide, although the remaining part consisted of miscellaneous sesquiterpenoids.
