Chemical Composition of Common Liverwort (Marchantia polymorpha L.) and Racomitrium Moss (Racomitrium canescens (Hedw.) Brid) in Korea

초록

Bryophytes are an important group of non-vascular land plants and can be classified into three sub-divisions such as mosses, liverworts, and hornworts. Among them, mosses and liverworts contribute considerably to the biodiversity of terrestrial ecosystems. Bryophytes contain a variety of volatile components with various biological properties. However, studies about the volatile composition of bryophytes are meager. Hence, the present study aimed to compare the essential oil composition of Marchantia polymorpha L. (liverwort) and Racomitrium canescens (Hedw.) Brid. (Racomitrium moss), which are widely distributed in Korea. Essential oils from M. polymorpha and R. canescens were obtained using the steam distillation method and their compositions were determined by gas chromatographymass spectrometry (GC-MS). The results revealed that essential oils of M. polymorpha and R. canescens registered markedly different chemical compositions. In M. polymorpha essential oil, widdrol (35.45%), thujopsene (11.20%), cuparene (7.67%), β-chamigrene (7.16%), α-bisabolol (6.69%), sativene (5.86%) were major components. Whereas the essential oil of R. canescens is mainly characterized by the estragole (58.86%) followed by D-limonene (7.20%). The GC-MS profiling of the essential oils extracted from these two species has been used in differentiating chemotypes within species. The data open new possibilities to understand the bioactive volatile components from Bryphytes.
