| 1 | Jatropha curcas L: Phytochemical, antimicrobial and larvicidal properties显示文摘Objective: To evaluate antimicrobial activities as well as the phytochemical and lavicidal properties of different parts of Jatropha curcas L.(J. curcas) growing in Mauritius.Methods: Determination of the presence of phytochemicals in the crude plants extracts by test tube reactions. Disc diffusion method and microdilution method were used to detect the antimicrobial sensitivity and activity(minimal inhibitory concentration). The crude solvent extracts were also tested on the larvae of two insects, Bactrocera zonata and Bactrocera cucurbitae(Diptera, Tephritidae).Results: The antimicrobial activities were significantly dependent for the different crude plant extracts on the thirteen microorganisms tested. For the Gram-positive bacteria, the crude ethyl acetate extract was more efficient compared to the Gram-negative bacteria with both solvents being effective. The crude ethyl acetate extract of J. curcas bark and mature seed oil showed the highest efficacy. The highest mortality percentage was observed after 24 h for both Diptera flies with(66.67 ± 2.89)% of Bactrocera cucurbitae larvae killed by ethyl acetate extract of J. curcas bark.Conclusions: This paper compared the different J. curcas plant sections with respect to the effectiveness of the plant as a potential candidate for new pharmaceuticals. The larvicidal effect was also studied in order to demonstrate the dual purpose of the plant. | Sillma Rampadarath Daneshwar Puchooa Rajesh Jeewon | 2016 | Asian Pacific Journal of Tropical Biomedicine2016，6，10： | 5 |
| 2 | In vitro antimicrobial and larvicidal properties of wild Ricinus communis L. in Mauritius显示文摘Objective: To explore the phytochemical and antimicrobial activities as well as the insecticidal properties of the different sections of Ricinus communis(castor) plant in Mauritius.Methods: Qualitative and quantitative methods were used for the determination of phytochemicals in the crude leaves, pericarp, seeds, bark and root extracts obtained by using polar and non-polar solvents. The disc diffusion and micro-dilution methods were used to evaluate the antimicrobial activities of the crude solvent extracts against 13 microorganisms. The insecticidal properties of the crude extracts on larvae of Bactrocera zonata(Diptera: Tephritidae), which caused important economic losses to local fruits were also investigated.Results: All the extracts from the different parts of the plant showed antimicrobial activity against most tested microorganisms. The polar solvents' extracts of the fully mature parts of the castor plant were active against the Pseudomonas aeruginosa(ATCC 27853),Escherichia coli(E. coli)(ATCC 25922), E. coli(0145:H28 Acc. No. CP006027.1) with inhibition zones ranging from 16 mm to 19 mm and against Bacillus cereus(ATCC11778)(B. cereus), Listeria innocua(ATCC 33090)(L. innocua). Lowest microbial inhibitory concentration was recorded for B. cereus, L. innocua, Staphylococcus aureus(ATCC 29213), E. coli(ATCC 25922) and Proteus mirabilis strain(NCTC 11938) with value of 3.2 mg/m L. The most active extract against both Gram-negative and Grampositive bacteria was extracted from the fully mature pericarps and it was the most active against E. coli(ATCC 25922), B. cereus, L. innocua and Staphylococcus aureus(ATCC 29213). In addition, the extracts obtained by using polar solvent and fully mature leaves demonstrated the strongest larvicidal activity against Bactrocera zonata(100%).Conclusions: Ricinus communis(castor) plant extracts possess larvicidal properties providing an effective eco-friendly control for fruit flies. The antimicrobial results justify the use of this plant in traditional medicine and the practice of supplementing decoctions/concoctions with conventional antibiotics. | Sillma Rampadarath Daneshwar Puchooa | 2016 | Asian Pacific Journal of Tropical Biomedicine2016，6，2： | 1 |
| 3 | An updated inventory of marine opisthobranch(Mollusca,Gastropoda)from the territorial waters of the Republic of Mauritius显示文摘Island ecosystems support diverse aquatic invertebrate communities comprising endemic taxa.Documentation of existing species is important for conservation.In this study,a checklist of marine opisthobranch from the Republic of Mauritius is presented.A combination of benthic surveys(50 m×5 m in triplicates),rover diving techniques and photo documentation were used over two years(2018–2020)within 35 sheltered and unsheltered lagoons.Morphological and molecular analysis were used for identification.Species composition within sheltered and unsheltered areas in Mauritius was estimated using the Bray-Curtis similarity.The checklist featured 117 species belonging to 61 genera and 28families,of which 13 are new records.The findings increased the knowledge of opisthobranch diversity from the Mauritius by 15.4%.Among the listed species,the distribution range of Cyerce nigra,Actinocyclus papillatus,and Phyllidia picta extended from the Western Pacific to the South Western Indian Ocean.Molecular analysis of the undescribed Gymnodoris sp.showed it resembled Gymnodoris sp.from Hawaii and were different by a genetic distance value of 10.6%.The species richness and evenness were higher within the sheltered regions of Mauritius which harboured the food resource of opisthobranch.These areas as compared to unsheltered regions were heavily populated,suggesting the probable influence of wave actions on opisthobranch diversity and abundance.The order Nudibranchia was reported as most speciose,with 86 species.The Sacoglossa and Nudibranchia were observed only on macroalgae and sponges respectively.High abundance was also recorded on shipwrecks which are the most common form of artificial reefs.With the inclusion of observations from previous studies,201species belonging to 94 genera and 36 families are now known from the Mauritius. | Lisa AH SHEE TEE Chandani APPADOO Daneshwar PUCHOOA Vishwakalyan BHOYROO | 2024 | Journal of Oceanology and Limnology2024，42，1： | 0 |
