Abstract

The crude ethanol extracts of four Indonesian medicinal plants namely Curcuma xanthorrhiza Roxb.,Phyllanthus niruri Linn., Andrographis paniculata Ness., and Curcuma aeruginosa Roxb. wereexamined for their antioxidant (radical scavenging) activity using 2, 2-diphenyl-2-picrylhydrazyl(DPPH) free radical and cytotoxicity using brine shrimp lethality test (BSLT). The total phenoliccontent was used the Folin-Ciocalteu method. IC50 values for DPPH radical scavenging activityranged from 14.5 to 178.5 μg/ml, with P. niruri having the lowest value and therefore the mostpotent, and C. aeruginosa having the highest value. LC50 values for BSLT ranged from 210.3 to593.2 μg/ml, with C. xanthorrhiza and A. paniculata having the lowest and highest values,respectively. The total phenolic content of the Indonesian plants ranged from 133.0 ±3.7 to863.3±54.7 mg tannic acid equivalent per 1 g extract, with C. aeruginosa and P. niruri having thelowest and highest values, respectively. A positive correlation between free radical scavengingactivity and the content of phenolic compounds was found in the four of Indonesian medicinal plants.

Abstract

Glucose oxidase is used in various industries for the development of enzymatic fuel cell. Based on prior studies, this compound is sourced from the local isolates of Aspergillus niger IPBCC 08.610, although investigations on the encoding gene have not been conducted. The purpose of this research, therefore, is to identify and characterized the gene responsible for encoding glucose oxidase, in the aspect of sequence, length, and restriction patterns. This experiment involved the amplification of genomic DNA using specific primers for gene recognition, which was followed by the restriction technique with EcoRI and PstI endonucleases. Furthermore, the gene is inserted into vector pGEM®T-Easy and transformed into competent E. coli DH5α cells, in an attempt to perform sequencing. The glucose oxidase gene from A. niger IPBCC 08.610 was confirmed to possess a size of 1848 bp, and a GC content of 57.8%, with a possibility of restriction into two fragments of size 908 bp and 980 bp, using the EcoRI restriction.

Abstract

The species Graptophylum pictum (L.) Griff, also known as “daun ungu” in Indonesia, is a traditional herbaceous plant believed to have antidiabetic potential. The number of people in the world with diabetes has increased dramatically over the recent years. The treatment of type II diabetes is complicated by several factors inherent to the disease. Elevated postprandial hyperglycemia is one of the risk factors and the intestinal digestive enzyme α-glucosidase plays a vital role in carbohydrate metabolism. One of the antidiabetic therapeutic approaches which reduces the postprandial glucose level in blood is by the inhibition of α-glucosidase. In this study, phytochemical analysis, α- glucosidase inhibitory activity and enzyme kinetics of ethyl acetate- and hexane extracts of G. pictum were evaluated with the aim to analyze its antidiabetic potential. Phytochemical analysis revealed the presence of tannins, steroids, and alkaloids. Steroids were present in ethyl acetate extract but absent in hexane extract, while alkaloids were present in hexane extract but absent in ethyl acetate extract. The ethyl acetate and hexane extracts had 30.68 and 49.82 % inhibitory effect on α-glucosidase activity respectively. The kinetics of glucosidase enzyme of ethyl acetate and hexane extracts were determined by Lineweaver Burk plots. These exhibited uncompetitive and noncompetitive inhibition to alpha-glucosidase activity respectively. From the enzyme assay, we infer that ethyl acetate and hexane extracts of G. pictum contain potential α-glucosidase inhibitors that have the potential to be exploited for use in the treatment of diabetes

Abstract

Ethanol is considered as the most promising alternative fuel, since it can be produced from a variety of agriculturally-based renewable materials, such as sugarcane bagasse. Lignocellulose as a major component of sugarcane bagasse is considered as an attractive renewable resource for ethanol production due to its great availability and relatively low cost. The major problem of lignocellulose is caused by its need for treatment to be hydrolyzed to simple sugar before being used for bioethanol production. However, pretreatment using acid as hydrolyzing agent creates some inhibitor compounds that reduce ethanol production because these compounds are potential fermentation inhibitors and affect the growth rate of the yeast. Reduction of these by-products requires a conditioning (detoxification and culture starter adaptation). Thus, the aim of this study was to evaluate bioethanol production by fermentation with and without detoxified sugarcane bagasse acid hydrolysate using adapted and non-adapted culture of C. tropicalis. According to this study, the highest ethanol amount was obtained about 0.43 % (v/v) with an ethanol yield of 2.51 % and theoretical yield of 4.92 % by fermentation of sugarcane bagasse hydrolysate with detoxification using the adapted strain of C. tropicalis at 72 hours fermentation time. Furthermore, the addition of 3 % glucose as co-substrate on detoxified-hydrolysate media only achieved the highest ethanol concentration 0.21 % after 24 hours fermentation with the ethanol yield 0.69 % and theoretical ethanol yield 1.35 %, thus it can be concluded that the addition of glucose could not increase the ethanol production.

Abstract

Temulawak or Curcuma xanthorrhiza Roxb, is usually used as traditional medicine (herbal medicine) that has antioxidant, anticancer, antihyperglycemic, anti-inflammatory, hepatoprotective and gastroprotective properties. The main components contained in temulawak responsible for its efficacy as a medicine are xantorhizol and curcuminoid. Curcuminoid has drawbacks, which are difficult to absorb and very quickly metabolized by the body, so that limit its bioavailability. The use of solid lipid nanoparticle carrier system (SLN) in form of palmitic acid, is known to improve the bioavailability of curcuminoid. This study aims to find the effective dose of nanocurcuminoid coated with palmitic acid that can be used as an anti-inflammatory agent. The methods used in this study, include the production of nanocurcuminoid with homogenization and ultrasonication methods, determination of particle size, polydispersity index, entrapment efficiency and anti-inflammatory activity test through rat feet edema. Nanocurcuminoid obtained in this study was 561.53 nm in size, with polydispersity index 0.309 and concentrations of curcuminoid absorbed and entrapment efficiency were 0.61±0.031 mg/mL, 58.93±3.021%, respectively. Anti-inflammatory activity of nanocurcuminoid through treated Sprague Dawley rats, showed that there were no significant difference compared with the positive control, curcuminoid extracts and empty nanoparticle. These results indicate that nanocurcuminoid with 175, 200 and 250 mg/kg.bw in doses, has greater anti-inflammatory activity (31.70%) compared to the other treatments.

Abstract

Wungu leaf (Graptophyllum pictum (L.) Griff) is a plant thought to have potential use in alleviating symptoms of diabetes mellitus. The purpose of the present study was to evaluate the activity of wungu leaf extracts in decreasing blood glucose level of alloxan (200 mg/kg BW)-induced hyperglycemic mice. Extracts of wungu leaf were obtained by macerating with ethanol and then partitioning the extract with diethyl ether, ethyl acetate, and butanol. Each extract obtained was used to treat hyperglycemic mice for 28 days. The results showed that wungu leaf extracts have the ability to decrease the blood glucose level of hyperglycemic mice (dose 50 mg/kg BW). The ethyl acetate extract showed the highest activity, bringing about a decrease of blood glucose of 37.6 %. The wungu leaf extract has the potential to be developed as a source of anti-diabetic agents.

Abstract

Diabetes mellitus is a chronic disorder that affects the metabolism of blood glucose inside the body. One of the alternative treatments is by using traditional medicinal plants, which have hypoglycemia effects. A mahogany seed is one of the traditional medicinal plants that has been proven to treat diabetes and has been used for generations. In the aqueous extract, ethanol 96 %, ethyl acetate, and hexane from mahogany seeds (Swietenia macrophylla King.) the inhibition of α-glucosidase activity are checked by measuring p-nitrophenol from p-nitrophenyl-α-D-glucopyranose (pNPG) on 400 nm. The percentage value of the inhibition for α-glucosidase ranged from 6,36-56,77 %, with 96 % ethanol extract that has the highest value and the hexane extract with the lowest value. Phytochemical screening revealed the presence of alkaloids, flavonoids, saponins, and triterpenoids, which could be responsible for the bioactivities shown by the 96 % ethanol extract and aqueous extract of S. macrophylla. Keywords : α-glucosidase activity, diabetes mellitus, mahogany seeds (Swietenia macrophylla King.), phytochemical screening.
