“…A África foi o terceiro continente que mais contribuiu com estudos, sendo a Nigéria um país com um total de três produções. (Ariyo et al, 2011) contribuíram elucidando a eficácia do extrato da Riccia nigerica Jones contra fungos que causam doenças em humanos, mas ressaltam que precisam ser realizados mais levantamentos etnobotânicos sobre plantas medicinais, principalmente sobre as briófitas, pois assim pode-se aumentar a exploração científica sobre esse grupo vegetal.…”

O artigo apresenta resultados de uma revisão sobre estudos da atividade biológica com briófitas em trabalhos realizados entre os anos de 2000 e 2019. Para a coleta de dados, utilizou-se as bases: Science Direct, Scopus e Google Acadêmico, os descritores foram: “bryophytes antifungal extracts” e “antifungal activities of bryophyte extracts”. Como critérios de inclusão: artigos com bioensaios e open acess. Como critérios de exclusão: artigos de revisão, perfil químico, livros, notas cientificas, breve relato e trabalhos em eventos. O status de conservação das espécies foi feita mediante busca no site da União Internacional para a Conservação da Natureza (IUCN). Foram selecionadas 53 publicações, oriundas de diversos continentes, destacando-se o continente asiático, especialmente a Índia com um total de 21 publicações. No que tange os anos de publicação, destaca-se o ano de 2011 com 9 publicações. A Marchantia polymorpha L. foi a espécie com mais estudos (sete). Oito espécies utilizadas nos estudos estão sob algum grau de ameaça, destaque para a Bryum cellulare Hook enquadrada como Em Perigo (EN). Pesquisas sobre atividade biológica de briófitas no que se refere a suas atividades antifúngicas já estão em desenvolvimento, contudo todos eles de fora do Brasil e com pouco destaque para a América.

“…The matured fruits of A. melegueta were bought in from Awolowo Market in Sagamu, while the matured fruits of C. gigantea and the seeds of B. sapida were collected at Sagamu and Ago-Iwoye respectively, both in the Ogun State, Southwestern Nigeria. The materials were also dried in the Gallemhamp oven (Aina et al, 2009b;Ariyo et al, 2011) and identification of the plants was done at the Herbarium of the Department of Plant Science, OOU, Ago-Iwoye.…”

“…It can also be used effectively against the growth of bacteria or yeast 5 . The crude extracts of R. nigerica showed significant antimicrobial activity against both bacteria and fungi and have the potential to be used as an alternative to drugs 6 . Riccia can also be used to treat skin allergy, sores and lip cracks by applying its decoction with vegetable oil 7 .…”

Two species of Riccia, namely Riccia billardieri and Riccia discolor, were studied to detect various amino acids qualitatively as well as quantitatively through HPLC. Seven amino acids (histidine, serine, tryptophan, asparagine, tyrosine, valine, and isoleucine) were observed to be common in both the species but varying significantly in their quantities. Riccia billardieri contained additionally four (lysine, glycine, cystine, and proline) amino acids and Riccia discolor one (glutamine) amino acid. The contents of histidine (0.597 mg g-1 dw) and asparagine (0.323 mg g-1 dw) were found higher in Riccia billardieri, but the concentrations of tryptophan (0.927 mg g-1 dw), serine (0.169 mg g-1 dw), tyrosine (0.024 mg g-1 dw), valine (0.394 mg g-1 dw) and isoleucine (1.770 mg g-1 dw) were higher in Riccia discolor. The value of asparagine was almost similar in both the species. In Riccia billardieri the concentration of histidine (0.597 mg g-1 dw) was observed maximum, whereas in Riccia discolor isoleucine (1.770 mg g-1 dw) was found in the highest amount. The presence of amino acids indicates the potential use of Riccia in the pharmaceutical and food industry. INTRODUCTION: Liverworts are known to have oil bodies, which consist of active chemical compounds. They produce several secondary metabolites such as diterpenoids, sesquiterpenoids and aromatic compounds 1. Bryophytes consist of many biological compounds like sugars, oligosaccharides, polysaccharides, amino acids, alcohols, fatty acids, aliphatic compounds, aromatic and phenolic substances 2. Traditionally, bryophytes were used to treat wounds, skin diseases, cuts and burns 3, 4. Riccia is a genus of thallose liverworts in the order Marchantiales and the family Ricciaceae.
