Background: Many traditional medicinal plants were studied for their phytochemical components. Dayak onions (Eleutherine bulbous (Mill.) Urb) is one of traditional medicinal plant in Indonesia. Analysis of the phytochemical compounds in the extract of the plant would help in determining various biological activities of the plant. Objective: This study was primarily aimed to identify the phytochemical profile of Dayak onions extract and its fractions. Methods: The Dayak onion bulbs were collected from Pancur Batu District, North Sumatra Province, Indonesia. Multiple solvents used to for extraction and analysis of phytochemical compound by chemical reactions, thin layer chromatography (TLC) profiling, and Fourier Transform Infrared Spectrophotometer (FTIR) profiling. Results: The phytochemical screening of Dayak onions ethanol extract showed it contained alkaloids, flavonoids, glycosides, tannins, and triterpenes/ steroids. The n-hexane fraction contained flavonoids and triterpenes/steroids, while the ethyl acetate fraction contains flavonoids and glycosides. The water fraction contained alkaloids, flavonoids, glycosides and tannins. By TLC profiling, the bioactive compounds in ethanol extract of the Dayak onion contain steroids, tannins, flavonoids and alkaloids. The bioactive compound in ethyl acetate fraction contains steroids, tannins, triterpenes, flavonoids and glycosides. The bioactive compound in n-hexan fraction contains steroids. The bioactive compound in water fraction fraction contains steroids and tannins. The FTIR demonstrated the presence of C-H alkanes, =C-H alkenes (aliphatic), C-O alcohol, ether, esters and carboxy acid in the ethanol extract, en-hexan fractions and ethyl acetate fractions. Conclusion: The phytochemical qualitative profiling showed that Dayak onion bulb as a rich source of bioactive compounds and have medicinal potential as therapeutic agent. A higher content of bioactive compounds of Dayak onion bulbs found in the ethanol and ethyl acetate extracts. The FTIR demonstrated the presence of C-H alkanes, =C-H alkenes (aliphatic), C-O alcohol, ether, esters and carboxy acid in the ethanol extract, enhexan fractions and ethyl acetate fractions.

The objective of this study was to evaluate phytochemical screening, antioxidants and antimicrobial activity of prickly pear pulp extract. Phytochemical screening was performed on the methanolic extract of the sample followed by gas chromatography mass spectrometry (GC-MS).The antioxidant activity was determined by measuring total phenolic content (TPC), ferric reducing antioxidant power (FRAP) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH). The antibacterial activity was determined using paper disc method against two bacteria namely Staphylococcus aureus and Escherichia coli. Total of 36 compounds belonging to phenolics, anhydrides, aldehydes, fatty acids and hydrocarbons were identified in the extracts. The highest content of total phenol and antioxidant activity (FRAP and DPPH) were found in methanol extract228.50 {\textpm} 3.67. mg GAE/100g DW, 118.63 {\textpm}3.86 mg TE/100g DW and 92.81\% respectively. The maximum zone of inhibition observed was 14.45 {\textpm} 0.67 mm against Staphylococcus aureus at methanol extract. It was concluded that fractions solvent plays important roles on the bioactive compound of prickly pear pulp extract and it can be used to control infectious diseases and prevent oxidative damage.

Background: Treatment for type-2 diabetes mellitus focuses on the incretin hormone, Glucagon-Like Peptide-1 (GLP-1). However, it has a short half-life. Inhibition of the enzyme Dipeptidyl peptidase IV (DPP IV) required maintaining the active form of GLP-1. Based on the previous studies on the highest activity of DPP IV enzyme inhibition of white tea extract, this study conducted on the fraction of white tea extract using rat blood serum (ex vivo). Objectives: This study aims to evaluate the inhibitory activity of fraction from white tea extract. Methods: White tea leaves extracted with ethanol. The inhibitory activity determined by using rat blood serum as DPP IV enzyme source (ex vivo), AMC (7-amino 4-methyl coumarin) as fluorescence substrate of DPP IV and sitagliptin as the standard reference. The the cleavage of fluorescence reaction product observed by a microplate reader with \λex = 360 nm and \λem = 460 nm at 37oC. Data expressed as mean \± SD and the IC50 value determined by nonlinear regression curve and fit using Prism Graph 7. Result: Methanol fraction (250 \μg/mL) has the greater inhibition percentage (50.487\%), and the fraction of n-hexane and ethyl acetate are 32.417\% and 36.541\%. The methanol fraction IC50 value is 227 \μg /mL. Conclusion: The methanol fraction is the most active to inhibit DPP IV enzyme.
