Antibacterial Activity of Extract from Swamp Plant of Eleocharis Dulcis

Abstract

The purpose of the research was to access bacterial activity from swamp plant extract of Eleocharis dulcis against Bacillus subilis, Pseudomonas aeruginosa and Vibrio cholera. The phytochemical compounds of ethanol extract of Eleocharis dulcis were tannins, flavonoids and triterpenoids. Phytochemical compounds of ethyl acetate and n-hexane extracts were flavonoids and triterpenoids. The maximum antibacterial activity the all of solvents in 2.000 ppm concentration. The bacterial activity of Eleocharis dulcis extract against Bacillus subtilis higher than that of Pseudomonas aeruginosa and Vibrio cholera.

Antibacterial Activity of Humped Bladderwort (Utricularia Gibba) Extracts Resulting From Multistage Extraction Method

“…The difference in extract yield in this test was caused because each solvent used had a different level of polarity. This research is in line with the results of Baehaki et al 7 , from water chestnut (Eleocharis dulcis)using n-hexane, ethyl acetate and ethanol extraction method indicating that ethanol extract produced a higher yield of extract than other solvents used, ethanol solvent had a higher level of polarity compared to other solvents. In addition, the high yield of ethanol extract is also due to the loss of non-polar and semipolar compounds that have been carried out in the extraction process n-hexane and ethyl-acetate of the multilevel extraction method.…”

Karakteristik Sensoris Fillet Ikan Patin (Pangasius sp.) dengan Penambahan Ekstrak Purun Tikus (Eleocharis dulcis)

“…Menurut Winarti (2010), setiap tumbuhan mengandung beberapa komponen bioaktif yang merupakan zat kimia alami pada tanaman yang dapat memberikan rasa, aroma dan warna pada tanaman. Menurut Baehaki et al (2018), kandungan komponen bioaktif yang dimiliki tumbuhan purun tikus yaitu steroid, terpenoid, tanin, saponin, flavonoid, dan fenol. Salah satu manfaat dari kandungan komponen bioaktif purun tikus yaitu sebagai senyawa antibakteri.…”

“…Salah satu cara penanganan untuk menghambat pertumbuhan mikroba yaitu dengan memperpanjang daya simpan filet ikan dengan pengawetan. Menurut Baehaki et al (2018), bahwa ekstrak purun tikus menunjukan aktivitas yang dapat menghambat beberapa bakteri patogen (Vibrio cholera) dan bakteri pembusuk makanan (Pseudomonas aeroginosa dan Bacillus subtilis). Dengan demikian, penelitian tentang penghambatan aktivitas mikroba pada filet patin perlu dilakukan menggunakan kombinasi ekstrak senyawa purun tikus dan penyimpanan dingin untuk mempertahankan daya simpan filet ikan Patin.…”

Antidiabetic and anticancer activity of Chinese water chestnut (Eleocharis dulcis) extract with multistage extraction

“…[ 1 ] Whereas Chinese water chestnut has been carried out qualitatively by phytochemical tests and Chinese water chestnut extract can function as a natural antibacterial. [ 2 ] The economic potential of Chinese water chestnut plants in the health sector is not well known and studied. This potential is related to the utilization of components contained in it.…”
