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

Melastoma affine plant has effect on health such as curing wound and toothache, also as an antimalarial drug. The fruit of this plant is purple and probably contain secondary metabolite compounds such as phenols and flavonoids. The total amount of both compounds may be different in unripe and ripe fruit. The aims of this research were to analyze secondary metabolite compounds and determine total phenol and total flavonoid of Melastoma affine fruit extract. The samples used in this study were unripe and ripe Melastoma affine fruits. Both of samples were extracted by three different solvents (water, 70% ethanol, and 96% ethanol) and obtained 6 extracts. Based on phytochemical test, each extract from unripe and ripe Melastoma affine fruit contained alkaloid, triterpenoid, flavonoid, phenol, and tanin. The extract with highest total phenols was 70% ethanolic extract from unripe fruit (189.56 mg/g GAE), while the extract with highest total flavonoids was 96% ethanolic extract from unripe fruit (225.50 mg/g CE). Based on this result, we conclude that unripe fruit of Melastoma affine has more total phenols and total flavonoids than ripe fruit.

Abstract

Rice husks contains 33.71% w/w lignocelluloses, the most abundantly available raw material on the earth for the production of biofuels and other valuable products. It is comprised of the carbohydrate polymers, cellulose, hemicellulose, and an aromatic polymer, lignin. One of the methods for removing the lignin component of rice husks is by delignification using white-rot-fungi. The aim of the study was to carry out delignification of rice husks using white-rot-fungi. The white-rot-fungi used here were Trametes versicolor and Phanerochaete chrysosporium. The study consisted of a biomass and microbial preparation, chemical assay of the rice husk, ligninase enzyme tests, and delignification of rice husks. Results showed that T. versicolor and P. chrysosporium have ligninase enzyme. The precentage of lignin from the total biomass rice husks was 23.61% w/w, and following the delignification process by T. versicolor for 20 days, the remaining lignin was 16.20% w/w, making the percentage of rice husks lignin degraded as 7.41% w/w. The biodelignification process also decreased the percentage of holocellullose, cellulose, and other extracted substances, and accordingly this increased the percentage of hemicellulose. Based on the ability of T. versicolor to degrade lignin of the rice husk at room temperature (28 ºC) as mentioned above, it can be concluded that T. versicolor has potential to be used for delignification process.

Abstract

Delignification is a lignin degradation, a preliminary process in industries that used cellulose containing substrates. Sengon logs are often used for the material in pulp industry because it has high levels of cellulose and low level of lignin. The aim of this study was delignification of sengon logs by using T.versicolor. The methods used include observation growth of T.versicolor compared with Phanerochaete chrysosporium, the rate of of lignin degradation (black liquor), delignification of sengon logs using T.versicolor and the chemical assay of sengon logs before and after delignification. The results of this study showed that delignification by T.versicolor was faster compared to P.chrysosporium based on the rate of lignin degradation (black liquor). The result showed that delignification by T.versicolor at room temperature reduced lignin of sengon logs by 37.31% within 20 days. Chemical assay performed on delignified sengon wood showed decreased level of ethanol benzene, soluble extractive substances, holocellulose, and cellulose and an increase of hemicellulose level.

Abstract

DNA barcoding has become a useful tool for identifying and confirming of species within a known taxonomic framework. A large-scale effort is underway to barcode all amphibian species using the universally sequenced DNA region, a partial fragment of mitochondrial cytochrome oxidase subunit I (COI). This study was aimed to use DNA barcoding technique to identify and confirm species of Polypedates leucomystax and to analyze their phylogenetic relationship. Samples of Polypedates leucomystax were collected from Campus Area of Bogor Agricultural University. The cytochrome oxidase I gene of 600-700 nucleotides were amplified and observed in agarose gel electrophoresis. Forward sequence (604 base pairs) of COI gene was used for phylogenetic analyses. BLAST analysis against BOLD System database showed 95.75% identity with sequences of Polypedates leucomystax. The pairwise genetic distances of Polypedates leucomystax with Rhacophorus schlegelii, Limnonectes fujianensis, Fejervarya cancrivora, and Bufo melanostictus were 0.274, 0.352, 0.339, 0.339, 0.393, respectively. These results illustrated that the genetic identification is congruence with the morphological identification. Phylogenetic tree analysis showed that the samples were in one clade with other tree frogs. The DNA barcoding technique based on the sequence of COI gene can therefore be used to identify and confirm species of Polypedates leucomystax.
