“…In C. pulcherrima endospermic gum, the M/G ratio is 2.8 (Andrade et al, 1999), but the sequential distribution of the galactopyranosyl unit is unclear. C. pulcherrima, a small tree known, as Pride of Barbados, "flamboianzinho", "flaboiant mirim", "barba de barata" and "brado de estudante", is widely used in many countries in popular medicine, showing many properties, including its use as an emmenagogue, antihemorrhagic agent and abortifacient and also in the treatment of infections (Alanis et al, 2005, Chiang et al, 2003, Patil et al, 1997. It is also greatly appreciated for its ornamental qualities with yellow, red, orange and pink flowers (Owens et al, 1995).…”

Recebido em 17/9/09; aceito em 2/2/10; publicado na web em 18/6/10The chloroform partition of methanol extract of leaves of Caesalpinia pyramidalis was submitted to different chromatographic procedures which afforded besides agathisflavone and taxifolin, the minor biflavones loniflavone, amentoflavone, 5'-hydroxyamentoflavone and podocarpusflavone A. The structures of the compounds were established on the basis of NMR and MS data analysis. Besides, the content of biflavones of different specimens of C. pyramidalis, which are collected in different habitats of the Brazilian semi-arid region, was determinated by LC-APCI-MS analysis. These analysis demonstrated that only the specimens harvested in Bahia state showed collectively the presence of agathisflavone, amentoflavone, sequoiaflavone and podocarpusflavone A.Keywords: Caesalpinia pyramidalis; biflavones; flavonoid analysis. INTRODUCTIONCaesalpinia pyramidalis Tul. is a tree belonging to the family Leguminosae-Caesalpinoideae, which is endemic of Brazilian northeastern, especially in the caatinga. It is popularly known as "catingueira" or "pau-de-rato" and its leaves are used in the preparation of infusions and decocts, which are used by the local population as diuretic, antidispeptic, stomach aches and for fever. 1 Species of this genus are known to present different biological activities. For instance, the extract of seeds of C. bonducella showed antimicrobial activities 2 and they are also employed in the treatment of diabetes. 3 Extracts of C. volkensii and C. pluviosa presents antimalarial activity 4 and C. pulcherrima antiviral activity. 5 The extract of C. pyramidalis is responsible for antibacterial, 6 larvicidal and moluscicidal 7 activities.The presence of diterpenes and flavonoids besides other phenolics is characteristic of this genus as well as the subfamily. 8 From the previous studies regarding with C. pyramidalis were isolated phenylpropanoids, biflavonoids, lignan, flavonoids besides gallic acid. 9 In the present study it was reported the isolation and characterization of the minor biflavonoids loniflavone (1), amentoflavone (2), 5¢-hydroxyamentoflavone (3) and podocarpusflavone A (5), besides agathisflavone (4) and taxifolin (6) from the leaves of C. pyramidalis (Figure 1). It was also evaluated by LC-MS the composition of biflavonoids present in leaves of specimens of C. pyramidalis collected in different habitats of Brazilian semi-arid region. EXPERIMENTAL General proceduresThe NMR spectra were obtained in Varian Gemini 2000, Inova 500 and Bruker AMX500 spectrometers operating at 300 and 500 MHz ( 1 H) and, 75 and 125 MHz ( 13 C), employing CD 3 OD, C 5 D 5 N and (CD 3 ) 2 CO as solvents and TMS as internal standard. The MS and the LC-MS analysis were carried out in a Shimadzu chromatographer mod. Bahia et al. 1298 Quim. Nova LCMS-2310, with autosampler 5 mL loop. The detection of biflavonoids was obtained in positive and negative APCI mode. The chromatograms were obtained using a VP-ODS (RP18 -5 mm; 3.9 x 150 mm) column and as mobile pha...

Antibacterial potency of methanol extracts of three green lower plants, Pneumatopteris afra, Platycerium bifurcatum and Nephrolepsis bisserata was determined using agar dilution method on clinical strains of Escherichia coli, Staphylococcus aureus, Klebsiella spp. and Salmomelia typhi. Antibacterial activities were observed at concentrations of 12.5, 25.0, 50.0 and 100.0 µg/ml. Their minimum inhibitory concentrations ranged from 12.5~100 µg/ml. Extracts of P. afra and P. bifurcatum were most active. Antibacterial activities observed with N. bisserata were less pronounced with no detectable activity at extract concentrations of 12.5 and 25.0 µg/ml. E. coli, together with S. aureus appeared to be the most susceptible of the test bacteria while Klebsiella spp. was least sensitive. The significance of our findings is discussed.
