Abstract

Dates seeds are one of the byproducts of the date palm juice industry which has the potential for further processing. Dates seeds contain active compounds that are known to have ability to inhibit αglucosidase. This study aims to measure the activity of 70% ethanol extract and the fraction of date palm seeds with a mechanism in inhibiting αglucosidase. The measurement of inhibitory activity was carried out by extracting date palm seeds using 70% water and ethanol. The extraction product is then fractionated with n-hexane, ethyl acetate, n-butanol, and water. Then the total phenolic and flavonoid calculations were calculated for each extract and fraction. Measurement of α-glucosidase inhibition activity was measured based on reaction of substrate to enzyme by the addition of inhibitors. The results showed that the ethanolextract had the highest total phenolic and flavonoid, which were 76.86 mg GAE / g and 21.19 mg QE / g, respectively. n-hexane fraction have the best inhibitory activity seen from the IC50 value, which is 12.69 mg/L. The kinetics of inhibition of 70% ethanol extract of date palm seeds are mixed inhibition. Keywords: α-glucosidase, date seeds, flavonoids, kinetic inhibition, phenolics

Abstract

The formation of prostaglandins and free radicals in the body occurs in response to inflammation. The use of non-steroidal synthetic drugs to overcome the effects of free radicals often causes harmful side effects to the body. Natural ingredients that have high antioxidant potential, such as curcumin, ginger are expected to overcome this problem. This study aims to measure the antioxidant potential of ginger nanocurcuminoid preparations coated with palmitic acid, by observing the lipid peroxide profile in the liver of inflammatory Spague-Dawley rats. SpagueDawley mice were induced with 1% carrageenan to trigger inflammation, then the lipid peroxide levels were measured after 24 hours. Measurement of lipid peroxide levels was carried out using a spectrophotometer with a wavelength of 532 nm. The size of the nanocurcuminoid preparation coated with palmitic acid was 561.53 nm with an IP value of 0.309. Lipid peroxide levels in the curcuminoid extract group at a dose of 100 mg / kg BW and the nanocurcuminoid group at a dose of 250 mg / kg BW were 0.27x10-4 nmol / g and 1.22 x10-4 nmol / g respectively. These showed that the antioxidant potential of temulawak nanocurcuminoids at a dose of 250 mg / kg BW was 114 times higher than that of curcuminoid extract at a dose of 100 mg / kg BW.

Abstract

According to reports, mango peel contains bioactive compounds—especially phenolic—threefold higher than the flesh. This issue underlies the research that aims to identify bioactive compounds from Indramayu mango peel which have the potential as ACE2 inhibitors. The study was initiated by extracting mango peel simplicia using aquadest, then carried out with phytochemical screening, and identification of compound content by LC-MS. The extraction obtained 21.3% of yield. The results of phytochemical screening showed that secondary metabolites in the form of alkaloids, flavonoids, saponins, and tannins were identified in the mango peel. At the same time, the LC-MS fragmentation results obtained 40 compounds based on the largest sample area. The result from fragmentation were tested for Lipinski bioavailability prediction and ADMET test and obtained 10 potential compounds. Molecular docking was performed on the ACE2 receptor with 10 sample ligands and 1 comparison ligand using YASARA Structure. All of the sample ligands (from Lipinski and ADMET test) showed higher free energies than comparison ligand, chloroquine. Mangiferin is a typical mango compound identified in LC-MS, had inhibitor activity against ACE2. Two-dimensional visualization using Discovery Studio showed mangiferin interaction with the receptor via hydrogen bond, hydrogen carbon bond and phi-anion interactions at three amino acid residues (Thr371, Glu375, Glu402) on the active site of ACE2.

Abstract

Glucose oxidase (GOX) is naturally produced by fungi Aspergillus niger. The GOX enzyme catalyzes the oxidation reaction of β-D-glucose to produce δ-gluconolactone and hydrogen peroxide a (H2O2). Hydrolysis of δ-gluconolactone will produce gluconic acid. Gluconic acid and its derivatives have benefits in the pharmaceutical field as a drug for mineral deficiencies. A. niger IPBCC 08.610 is a local isolate that produce intracellular GOX with higher yield than extracellularly. GOX can be expressed extracellularly by cloning into the expression vector pPICZαB which has the signal peptide α-mating factor (α-MF). GOX gene construction needs to be done by adding some features such as XhoI restriction sites at the 5' and 3' ends, XbaI restriction site at 3’ side, and spacer peptide glu-ala-glu-ala at 5’ side. This research aims to optimize Polymerase Chain Reaction (PCR) conditions in two stages of amplification, stage I to copy the GOX gene and stage II to add those features so it is hoped that recombinant GOX can increase gluconic acid production. The results of primer concentration optimization showed that primers with a concentration of 10 µM produced clearer PCR amplicons than those with a concentration of 20 µM. The optimal temperature for amplification stage I is 58°C. The amplification stage II annealing temperature was modified with the first ten cycles based on the lowest Tm of primer value, 52°C, and the subsequent 25 cycles based on the highest Tm of primer value, 61°C.
