          Abstract

          RESUMO Byrsonima verbascifolia Rich ex. A. Juss é uma espécie do cerrado brasileiro com uso etnobotânico vasto. O objetivo desse trabalho foi realizar um levantamento bibliográfico de artigos originais e revisões, indexados até agosto de 2014 nas bases de dados Periódicos CAPES, Scielo, Scopus, Web of Science e Medline, nos idiomas português e inglês, utilizando a palavra-chave Byrsonima verbascifolia. Foram contemplados a composição química e os aspectos botânicos, etnobotânicos e farmacológicos. Os estudos presentes na literatura avaliaram as atividades antioxidante, antifúngica, antiviral, antimicrobiana, moluscicida, antimutagênica, mutagênica, teratogênica, imunomodulatória, tóxica e citotóxica de extratos dessa espécie. Apenas um estudo avaliou a atividade da Byrsonima verbascifoliaRich ex. A. Juss in vivo, sendo comprovado que o extrato hidrometanólico das folhas não induz teratogênese, mutagênese ou efeito estimulante ou depressor da resposta imune. Metodologias in vitro predominaram o que demonstra a necessidade de investigação científica empregando testes in vivo para a melhor avaliação das outras atividades biológicas mencionadas.

          ABSTRACT Byrsonima verbascifolia is a species of Brazilian cerrado with extensive ethnobotanical application. The aim of this study was to perform a bibliographic description of original papers and reviews indexed until August 2014 in the databases of the CAPES Digital Library, Scielo, Scopus, Web of Science and Medline, written in Portuguese and English, using the keyword Byrsonima verbascifolia. The chemical and botanical compositions and the ethnobotanical and pharmacological aspects were contemplated. The researches in the reports evaluated the antioxidant, antifungal, antiviral, antimicrobial, molluscicide, antimutagenic, mutagenic, teratogenic, immunomodulatory, toxic and cytotoxic activities of the extracts of this specie. Only one study evaluated the in vivo activity of the Byrsonima verbascifolia Rich ex. A. Juss and proved that the hydromethanolic extract from the leaves does not induce teratogenesis, mutagenesis, stimulant or depressant effect of the immune response. The In vitro methodologies represented the higher number of researches demonstrating the need of scientific investigation using in vivo tests for better assessment of other biological activities mentioned.

          Biological screening of Brazilian medicinal plants.

          In this study, we screened sixty medicinal plant species from the Brazilian savanna ("cerrado") that could contain useful compounds for the control of tropical diseases. The plant selection was based on existing ethnobotanic information and interviews with local healers. Plant extracts were screened for: (a) molluscicidal activity against Biomphalaria glabrata, (b) toxicity to brine shrimp (Artemia salina L.), (c) antifungal activity in the bioautographic assay with Cladosporium sphaerospermum and (d) antibacterial activity in the agar diffusion assay against Staphylococcus aureus, Escherichia coli, Bacillus cereus and Pseudomonas aeruginosa. Forty-two species afforded extracts that showed some degree of activity in one or more of these bioassays.

            Natural products with hypoglycemic, hypotensive, hypocholesterolemic, antiatherosclerotic and antithrombotic activities.

            H. Ng, P. Wang (1998)
            This article reviews compounds of botanical origin which are capable of lowering plasma levels of glucose and cholesterol and blood pressure, as well as compounds inhibiting atherosclerosis and thrombosis. Hypoglycemic natural products comprise flavonoids, xanthones, triterpenoids, alkaloids, glycosides, alkyldisulfides, aminobutyric acid derivatives, guanidine, polysaccharides and peptides. Hypotensive compounds include flavonoids, diterpenes, alkaloids, glycosides, polysaccharides and proteins. Among natural products with hypocholesterolemic activity are beta-carotene, lycopene, cycloartenol, beta-sitosterol, sitostanol, saponin, soybean protein, indoles, dietary fiber, propionate, mevinolin (beta-hydroxy-beta-methylglutaryl coenzyme A reductase inhibitor) and polysaccharides. Heparins, flavonoids, tocotrienols, beta-hydroxy-beta-methylglutaryl coenzyme A reductase inhibitors (statins), garlic compounds and fungal proteases exert antithrombotic action. Statins and garlic compounds also possess antiatherosclerotic activity.

              Flavonoids and antiulcerogenic activity from Byrsonima crassa leaves extracts.

              Byrsonima crassa Niedenzu (IK) (Malpighiaceae) is used in Brazilian folk medicine for the treatment of diseases related mainly to gastric ulcers. In this study, we evaluated the potential antiulcerogenic effect of three different extracts obtained from the leaves of Byrsonima crassa namely hydromethanolic (80% MeOH), methanolic (MeOH) and chloroformic extracts (CHCl(3)). The oral administration (250, 500 and 1000 mg/kg) of all the extracts reduced the formation of lesions associated with HCl/ethanol administration in mice. The 80% MeOH extract significantly reduced the incidence of gastric lesions by 74, 78 and 92% at doses of 250, 500 and 1000 mg/kg, respectively (P<0.01). The MeOH extract reduced the ulceration by 93 and 99% only at the doses of 500 and 1000 mg/kg (P<0.01). The lower gastroprotective action (69%) was observed when animals were treated with CHCl(3) extract at the dose of 1000 mg/kg (P<0.01). Phytochemical investigation of Byrsonima crassa afforded five known substances: quercetin-3-O-beta-d-galactopyranoside, quercetin-3-O-alpha-l-arabinopyranoside, the biflavonoid amentoflavone, (+)-catechin and (-)-epicatechin. The presence of these phenolic compounds may probably explain the antiulcerogenic effect of the extracts of Byrsonima crassa leaves.
