Este estudo teve por objetivo reunir e analisar evidências científicas sobre a eficácia de duas abordagens terapêuticas disponíveis para alívio dos sintomas em pacientes com síndrome do intestino irritável (SII), o cloridrato de mebeverina e o óleo de hortelã-pimenta (Mentha x piperita L.). Uma revisão crítica sistematizada foi realizada a partir das bases de dados MEDLINE, CENTRAL e LILACS. Onze artigos referentes à ensaios clínicos randomizados abrangeram os critérios de elegibilidade. Os achados sugerem baixa evidência da mebeverina no controle dos sintomas intestinais da desordem, ainda que, apenas um dos estudos preocupou-se em relatar a ocorrência de efeitos adversos. Já o óleo de hortelã-pimenta mostrou-se eficaz e bem tolerado para a redução do quadro. Escalas de qualidade de vida também obtiveram resultados positivos com a fitoterapia. A busca por efeitos adversos durante o tratamento foi abordada em praticamente todos os ensaios. Em suma, as evidências apontam positivamente para o uso do fitoterápico no alívio dos sintomas da síndrome do intestino irritável, todavia a mebeverina permanece comercializada a um custo elevado e carece de estudos que demonstrem sua eficácia. Reforça-se a necessidade de investigações com métodos de qualidade criteriosos capazes de auxiliar boas escolhas terapêuticas na prática clínica.

A simple, repeatable and efficient protocol for direct multiple shoot regeneration from internodal explants has been defined in peppermint ( Mentha x piperita var. Indus). In vitro regenerated shoots of peppermint were excised into 4 to 8 mm long internodes and cultured on Murashige and Skoog's medium supplemented with different cytokinins. In the hormonal assay, 3.0 mg L-l zeatin or 6-isopentenyl adenine independently supplemented to half strength MS medium exhibited multiple shoot regeneration, while thiaduzorn (0.1-3.0 mg L−1) showed no morphogenetic effect. A maximum of 85% in vitro cultured explants showed multiple shoot formation with an average of 7 shoots per explant on MS medium supplemented with zeatin. Multiple shoots were initiated within three weeks of cultivation. Internodes with regenerated multiple shoots were transferred to half - strength MS medium without supplementing with any plant growth hormone for shoot elongation and rhizogenesis. Rooted plants acclimatized and grew to maturity under glasshouse conditions. The plantlets developed were phenotypically identical to the parent plant and exhibited 96 % survival.

Seven extracts were prepared from Mentha x piperita (peppermint) leaves in sequence using a Soxhlet apparatus, viz. (40-60°) light petroleum (PE), dichloromethane (CH2Cl2), acetonitrile (ACN), ethyl acetate (EtOAc), methanol (MeOH), n-butanol and water (H2O) extracts. The phenolic and flavonoid content of each extract were estimated using spectrophotometric methods whilst a qualitative-quantitative analysis was made by reverse-phase high performance liquid chromatography coupled with photodiode array detection (HPLC-PDA). Each extract was assessed in a battery of six antioxidant-related assays so as to determine their iron(III) reductive, iron(II) chelating and free radical scavenging abilities. The MeOH-soluble extract contained the greatest content of total phenols and flavonoids based upon the Folin-Ciocalteu and 2-aminoethyl diphenylborate reagent data and HPLC-PDA analysis. Based upon the chromatographic and UV-spectral data, the leaves principally contained the cinnamic acid caffeic acid, the depside rosmarinic acid and flavonoids (flavones and flavanones). Eriocitrin (383.3 ± 2.2 mg/g extract) and rosmarinic acid (381.2 ± 1.9 mg/g extract) were the most abundant components identified within the leaves, whilst naringenin-7- O-glucoside (0.8 ± 0.01 mg/g extract) was the least abundant component identified being found only in the EtOAc-soluble extract. The EtOAc, ACN and H2O-soluble extracts demonstrated the most potent iron(III) reductive and 1,1′-diphenyl-2-picrylhydrayl, 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonate) and hydroxyl free radical scavenging properties; however, the H2O and CH2Cl2-soluble extracts were the most potent extracts in the β-carotene-linoleic acid bleaching inhibition assay. In terms of iron(II) chelation – an important antioxidant property - the PE, MeOH and H2O extracts demonstrated moderate iron(II) chelating activity.
