Abstract

Biosciences and biotechnology have become the interesting topics since long to be investigated in order to understand science and technology, develop many tools and instrumentation, discovery of new drugs including natural base drugs and biopharmaceutical, contribute in energy sources, interact with the environment as well as to improve the quality of human being. The researches of the field have dramatically contributed for many other field and for better life. Uncounted numbers publications in these field will be continuously rising. To contribute in dissemination of research output which have been done by researcher around the world, the Current Research on Biosciences and Biotechnology so called CRBB is published in this year. In the beginning this journal will publish 2 issue in the year and will be increased in the future. All researchers in the field of bioscience and biotechnology are invited to submit the manuscripts to CRBB. The manuscript will be peer reviewed prior to publish.

Abstract

A flavonoid, luteolin, was isolated from the leaves of Syzygium myrtifolium . The compound was purified using vacuum liquid chromatography with the help of a specific guidance for the flavonoid isolation. The chemical structure of this compound was determined based on measurements of UV, IR and NMR spectroscopic data. The occurrence of luteolin in S. myrtifolium is firstly reported from this study.

Abstract

Ursodeoxycholic acid (UDCA), a secondary bile acid (BA), is an acidic steroid synthesized from cholesterol in hepatocytes. UDCA is widely used for the treatment of various diseases related to liver injury. The use of UDCA to treat non-liver diseases has also been developed recently, such as neurodegenerative diseases, cancer, and obesity. Due to the important role of UDCA on human health, numerous studies in understanding its chemical and pharmacological properties have been published. Literature sources were obtained from online databases such as Science Direct, Google Scholar, Scopus and PubMed using keywords relating to the purpose of study. Critical analysis and review were performed for all literature. UDCA is a steroid compound with pharmacological properties. Seventeen enzymes are involved in its biosynthesis, which has been proposed in four pathways: classic, alternative, the Yamazaki, and 25-hydroxylation pathways. UDCA can be isolated from bovine bile, bear bile or all Ursidae, human, rabbit, cow, rat, hamster, sheep, pig, and plant. UDCA has been used in the treatment of several diseases such as primary biliary cirrhosis, intrahepatic cholestasis of pregnancy, hepatolithiasis associated with Caroli syndrome gallstones, cystic fibrosis, hepatitis C virus, chronic heart failure, neurodegenerative diseases, and obesity, as well as in the prevention of cancer. UDCA has a wide range of pharmacological properties. Further investigations on its efficacy and safety on humans are required before it could be used for several indications. All genes which are responsible in UDCA biosynthesis have been elucidated. That said, further genetic engineering studies in order to find other prospective sources of UDCA could be a challenge for the future research.

Abstract

Meniran (Phyllanthus niruri L.) is a wild plant in the Euphorbiaceae family which grows in tropical climates. The plant is known to possess antioxidant activity and is rich in phenolic compounds. Since plants with high phenolic content and high antioxidant activity are known to exhibit high tyrosinase inhibitory activity, the purpose of this study is to determine the inhibitory activity of the tyrosinase enzyme by the methanol extract of meniran (P. niruri L.) and to isolate secondary metabolites from the extract and fractions which exhibit inhibitory activity against tyrosinase. The in vitro tyrosinase inhibitory activity assay was conducted using the 96-well microplate method with kojic acid as the positive control, while the separation and purification of compounds were carried out using chromatography techniques. The methanol extract and n-hexane fraction showed tyrosinase inhibitory activity with IC50 of 11.05±0.16 and 2.57±0.08 mg/ml, respectively. Three bioactive compounds were succesfully isolated from the n-hexane fraction. Based on the UV and NMR spectra, compounds 1, 2, and 3 were identified as phyllanthin, phyltetralin, and hypophyllanthin, respectively. Furthermore, phyllanthin (1) was shown to demonstrate inhibitory activity against tyrosinase with IC50 of 0.6322 mM. In conclusion, both meniran extract and phyllanthin (1) were found to exhibit inhibitory acitivity against the tyrosinase enzyme. In the future they can be candidates for the treatment against hyperpigmentation and also as an active ingredient in skincare formulations.
