These effects can be attributed to the presence of substantial and possible synergies of the chemical components viz., anthraquinones, coumarins, anthracene derivatives, mono-, sesqui-
and diterpenes, triterpenes and steroids, as well as water-soluble tannins.
According to the phytochemical studies on the liverworts, a wide variety of the terpenoid derivatives such as mono, sesqui-
and diterpenes which are mainly accumulated in nonpolar fractions as well as aromatic and phenolic compounds have been isolated from too many liverworts collected different places of the world (11).
and diterpenoids from the argentine liverwort Porella chilensis.
Patchouli oil is unique because it consists of over 24 different sesquiterpenes rather than a blend of different mono-, sesqui-
and di-terpene compounds.
