Context: Liverworts (Marchantiophyta) are the second largest group of bryophytes exhibiting promising pharmacological and biological activities. They have been used as remedies for cuts, fractures, burns, bruises, open wounds, inflammation and pneumonia. Objective: In the present study, eight liverwort species [ Corsinia coriandrina (Spreng.) Lindb. (Corsiniaceae) , Mannia androgyna (L.) A. Evans (Aytoniaceae) , Plagiochasma rupestre (J.R. Forst et G. Forst) Steph. (Aytoniaceae) , Porella cordaeana (Huebener) Moore (Porellaceae) , Porella platyphylla (L.) Pfeiff. (Porellaceae) , Reboulia hemisphaerica (L.) Raddi (Aytoniaceae) , Riccia fluitans L. (Ricciaceae) , and Targionia hypophylla L. (Targioniaceae)] have been investigated for their phytochemical composition and pharmacological effects as a function of anti-inflammatory and antinociceptive potentials, in connection with the major volatile components of the extracts. Material and methods: The chemical compositions of these species and major constituents were identified using GC/MS. In addition, carrageenan-induced paw edema and p-benzoquinone-induced abdominal constriction models were used for the activity assessments. Results: Sesquiterpenes were detected as common constituents of all liverworts. The in vivo experimental models revealed that P. cordeana, P. rupestre and R. haemispherica show significant inhibitory effect on carrageenan-induced paw edema with the inhibition values of 25.4, 27.2 and 29.4%, respectively. Porella cordaeana, P. platyphylla, P. rupestre and R. haemispherica exhibit promising suppressing effect on p-benzoquinone-induced abdominal constriction animal models with the values of 27.6, 31.5, 44.6, and 41.1%, respectively. Discussion: It is suggested that the sesquiterpenes are partly responsible for mentioned activities of the liverworts. Conclusion: The present study confirms the claimed anti-inflammatory activity of liverworts in a scientific platform. [ABSTRACT FROM AUTHOR] |
