This study aims to determine the content and total levels of secondary metabolites of ethanol extract of moringa seed (Moringa oleifera Lam.). Extraction of moringa seed using the maceration method to obtain a filtrate. The filtrate obtained was concentrated using a rotary evaporator to obtain a concentrated extract. The extract was tested qualitatively for alkaloids, flavonoids, saponins, and tannins using a suitable reagent with the test parameters. The quantitative test was using UV-Visible spectrophotometry. Alkaloids using test parameters equivalent total alkaloid quinine, flavonoids use parameter test equivalent of the total flavonoids quercetin, saponin using test parameters from Quillaja total saponins and tannins quantitative bark using test parameters total tannin tannic acid equivalent. The result showed that moringa seed positive for alkaloids characterized by orange deposition, flavonoids are characterized by the formation of the yellow color orange, saponin their stable foam, and tannins are marked in black. Quantitative test results alkaloids of 916,87 µg/g, flavonoids of 0.255%, saponin of 6.367%, and tannin of 3,724.5 µg/g.

Background: This research aimed to examine the secondary metabolites in the ethanol extract of Parkia speciosa Hassk peels and determine the effect of the P. speciosa Hassk peels on the reduction in total cholesterol levels of male hypercholesterolemia white rats.Methods: Thirty white male rats were divided into six treatment groups (n=5): Group I: normal control (0.5% CMC Na suspension), Group II: negative control (high cholesterol feed), Group III: positive control (suspension simvastatin), Group IV, V, VI: hypercholesterolemia rat received P. speciosa Hassk shell at dose of 300, 400, and 500 mg/kg BW orally for 14 days. The total cholesterol levels were measured on days 0, 14, 28, 35.Results: Quantitative test showed that the ethanol extract of P. speciosa peels contained 0.21% alkaloids (w/w), 8.34% flavonoids (w/w), 4.21% tannins (w/w) and 0.18% saponins (w/w). The ethanol extract of P. speciosa peels at a dose of 300 mg/kg BW was able to reduce total cholesterol levels in hypercholesterolemia white mice (52 mg/dL).
Conclusion:The ethanol extract of P. speciosa peels can be considered as an effective treatment for hyperlipidemia disease.
Complications of diabetes mellitus cause diabetic nephropathy. Soy-yamghurt is made from a combination of Banggai sweet potato juice and fermented soybean juice to be a functional food for diabetic nephropathy sufferers. This study aimed to analyze quantitatively the secondary metabolites contained in soy-yamghurt and to determine the effectiveness of soy-yamghurt in reducing urea and creatinine levels. This study used an experimental method with a total of 25 rats divided into 5 groups, namely normal control, negative control, soyyamghurt treatment group with a comparison of yam and soybean extract, namely F1(1:1), F2(1:2), and F3(2:1). The parameters observed were urea and creatinine levels on days 0, 7, 14, 21, and 28. The results obtained were the total levels of secondary metabolites of Alkaloid compounds F1 0.10% v/v, F2 0.01% v/v, and F3 0.01% (v/v), Flavonoid compounds F1 0.14% (v/v), F2 0.12% (v/v), F3 0.13% (v/v), Tanin compounds F1 0.27% (v/v), F2 0.26% (v/v), F3 0.14% (v/v) and saponins F1 1.15% (v/v), F2 1.22% (v/v), F3 1.25% (v/v). Administration of soy-yamghurt F2 was effective in lowering urea and creatinine levels. With an average value of 14.66 mg/dL urea and 0.40 mg/dL creatinine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
