Abstract

Rambai laut (Sonneratia caseolaris L. Engl) is one of the typical plants of Borneo that the leaves are empirically used by the community as a medicinal plant. Compounds from plants can be obtained by extraction. The yield rendement on the extraction process can be influenced by several factors, one of which is the method of extraction. This study aims to determine the effect of extraction methods and the amount of yield produced on rambai laut extracts. The research design is experimental with descriptive analysis. Rambai laut which has become powder then in extraction by using maseration method, infundation method, reflux method and soxhletasi method. The result of rendement is then analyzed using statistic. Soxhletasi method yield average value of rendemen that is equal to 28,38%, reflux equal to 25,57%, maseration equal to 21,28% and infundasi with average value of rendemen that is equal to 17,20%. The soxhletation method yields the highest average yield value and infundation with the lowest average yield value. The result of staitistic test shows that the extraction method has an effect on each rendement with p value = 0,024 <α = 0,05.

Exploration and preliminary analysis of sengkubak (Pycnarrhena cauliflora (Diels)) as natural food flavouring additive prospect

“…Besides that, ethanol is a polar solvent that can form hydrogen bonds and evaporate faster during the evaporation process [24]. The high yield value indicates the high bioactive content in it, and the extract yield is influenced by the type of solvent, the extraction method used, and the required extraction time [26,27,28]. Each of these extracts then being analysed for glutamic acid content using UPLC (Table 4).…”

Extraction methods effect on antioxidant activity of ethanol extract of ‘pasak bumi’ (Eurycoma longifolia Jack.) root

“…Based on Table 1, rendement of hot water percolation > maceration > soxhletation > reflux > ethanol 96% percolation. Rendement is influenced by several factors including the extraction method, the number of solvents and the type of solvent used [21][22][23]. The maceration method will produce more yields than the percolation method, because in maceration stirring occurs to accelerate the dissolution process by the analyte, compared to percolation which is not stirred and only immersed in the process [23].…”

The maceration method will produce more yields than the percolation method, because in maceration stirring occurs to accelerate the dissolution process by the analyte, compared to percolation which is not stirred and only immersed in the process [23]. The rendement of the maceration and percolation methods using 96% ethanol as a solvent showed the appropriate results, where the maceration was higher than the percolation rendement.…”

UJI DAYA HAMBAT EKSTRAK ETANOL DAUN RAMBAI (Sonneratia Caseolaris (L) Engl) TERHADAP BAKTERI Propionibacterium acnes DAN Staphylococcus epidermidis

“…Tumbuhan rambai secara empiris di manfaatkan masyarakat Kalimantan Selatan sebagai obat luka. beberapa masyarakat juga memanfaatkan daun rambai untuk ditambahkan pada pembuatan bedak dingin (6).…”

“…penelitian sebelumnya tentang perbandingan metode ekstraksi daun rambai diperoleh hasil randemen ekstraksi dengan metode maserasi, infudasi, soxhletasi dan refluks berturut-turut 21,28%; 17,20%; 28,38% dan 25,57% (6) . Hasil tersebut menunjukan bahwa metode ekstraksi UAE pada penelitian ini memiliki randemen yang lebih kecil jika dibandingkan metode ekstraksi konvensional.…”
