Plant Biosystems (Impact Factor: 1.92). 11/2009; 2009(143):431–434. DOI: 10.1080/11263500903172110

ABSTRACT

Azolla filiculoides showed a planar development in four culture media, but with overlapping of sporophytes after 28 days, and curled roots in all cases except for IRRI2. The difference in biomass between the media IRRI2 and IRRI1-Fe10x was statistically significant at Days 14, 21 and 28 by ANOVA. Medium IRRI2 gave the highest duplication time.

    • "Even so, some compounds already identified in Azolla species could be related with the activities demonstrated in this research . The phenylpropanoids α-asarone and isoeugenol methyl ether of A. filiculoides (Greca et al. 1989), the volatile compounds such trans-2-hexenal and geraniol of A. filiculoides (Pereira et al. 2009), the anthraquinones of A. microphylla (Abraham and Aeri 2012) and the flavonoids, phenols or coumarins of A. microphylla (Abraham 2013) can have bioactivity against fungi and bacteria. The high MIC values found for both antibacterial and antifungal extracts probably indicate that compounds responsible for those activities may be present in very low levels in the pool of compounds that compose the extract.

    ABSTRACT: Previous reports indicate the use of the aquatic fern Azolla as medicinal plant in New Zealand and Tanzania against sore throat and cough, respectively. Therefore, the aims were to evaluate the bioactivity of Azolla organic and aqueous extracts against bacteria and yeasts. Organic (dichloromethane:methanol) and aqueous extracts obtained from six Azolla species were tested against bacterial pathogenic and non-pathogenic strains (four Gram-positive and three Gram-negative) and pathogenic fungi (three clinical isolates of Candida albicans and one of C. glabrata), using the agar diffusion method and the broth microdilution assay. The results showed that organic extracts of A. caroliniana and A. rubra and of A. filiculoides inhibited the growth of B. subtilis ATCC 6633 whereas those of A. caroliniana and A. microphylla inhibited the growth of S. aureus ATCC 25923. The MICs were higher than 4 mg/ml for A. caroliniana, A. microphylla and A. rubra and higher than 3.25 mg/ml for A. filiculoides. Aqueous extracts of A. filiculoides, A. caroliniana, A. microphylla, A. rubra and A. pinnata var. pinnata induce a small inhibition zone (1 mm) in C. albicans ATCC 10231 with a MIC higher than 12.5 mg/ml. In conclusion, organic and aqueous extracts of some Azolla species show potential for use against infections caused by Gram-positive bacteria and C. albicans, respectively.

    ABSTRACT: Azolla microphylla Kaulf. is an aquatic nitrogen fixing pteridophyte commonly found in aquatic habitats including paddy fields. Methanolic extract of the fronds of A. microphylla was subjected to partial purification by solvent partitioning with diethyl ether and ethyl acetate followed by hydrolysis, and further partitioning with ethyl acetate. The two fractions, thus obtained were tested for antibacterial activity. It was observed that the ethyl acetate fraction inhibited the growth of the pathogenic bacterium Xanthomonas oryzae. The GC-MS analysis of the ethyl acetate fraction showed several prominent peaks with retention time ranging from 8.83 to 45.54 min. A comparison of these peaks with the GC-MS libraries revealed that it could be eicosenes and heptadecanes with potential of antimicrobial activity.
