<!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:AllowPNG /> </o:OfficeDocumentSettings> </xml><![endif]--><p>A <em>Nephrolepis pectinata </em>conhecida popularmente como samambaia paulista, escadinha-do-céu, rabo-de-gato, pertence à família das Davalliaceae. Pela beleza dos arranjos de suas folhas as samambaias são bastante comercializadas no Brasil, no entanto, ainda não foram descritos na literatura estudos sobre seu potencial farmacológico. Desta forma, o objetivo desta pesquisa foi analisar as propriedades fitoquímicas do extrato bruto das folhas de <em>Nephrolepis pectinata. </em>Para realização das análises fitoquímicas foram realizados inicialmente a coleta do vegetal, preparação da exsicata, lavagem, secagem e trituração. Em seguida, a extração pelo método de percolação e por final as análises fitoquímicas. Os resultados preliminares fitoquímicos do extrato bruto das folhas de <em>Nephrolepis pectinata </em>apresentaram resultado positivo para açúcares redutores, fenóis/taninos (taninos catéquinos) e catequinas.</p><!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves /> <w:TrackFormatting /> <w:HyphenationZone>21</w:HyphenationZone>
