Abstract

Plants have been the chief source of compounds of medicine for thousand of years. Plants are also the source of many medicines for the majority of the worldÂ’s population. The role of biotechnology is very important for multiplying, conserving the spesies, and enhancing the production of secondary metabolites. Endophytes are microbes that inhabit plants are currently considered to be a wellspring of novel secondary metabolites offering the potensial for medical and industrial exploitation. Natural products from various endophytic microbes have been investigated. Some examples of natural products observed from endophytic microbes are antibiotics, antiviral compounds, anticancers, antimalarial compounds, antioxidants, antidiabetics, and immunosuppressive compounds.

Abstract

Antioxidant activity and identification of antioxidative compounds of Callyspongia sponge from Seribu Island (Kepulauan Seribu) were investigated. The sponge was extracted with acetone and the extract was concentrated using rotary vacuum evaporator. DPPH and tiocyanate methods were used to examine the antioxidant activity of the extract. The extract exhibited strong antioxidant activity in DPPH method with IC50 of 41.21 µg/ml. Chemical analysis indicated that the antioxidative compound in the sponge was alkaloid group.

Abstract

Chitosan is a polycatonic biopolymer that can form gel in acidic environment so that can be used as a hydrophilic matrix in controlled release drug delivery system. In this research, propranolol hydrochloride controlled release granule was made in chitosan matrix. Granules were made by wet granulation method with variety of matrices, i.e. chitosan, hydroxypropyl methylcellulose (HPMC) and ethyl cellulose (EC). HPMC and EC were used as a comparing matrix. The release rates of propranolol HCl from matrix were determined by using dissolution apparatus type I with 50 rpm stirring rotation in acidic media of pH 1,2 and base media of pH 7,5 for 8 hours. Sample was taken at certain time and the samples were analyzed by spectrophotometer. The result showed that the release of propranolol hydrochloride from chitosan matrix was the slowest compared to the other matrices.

Abstract

A method by high performance liquid chromatography for the analysis of acrylamide in potato chips, is reported. The retention time for the elution of acrylamide from the C18RP column ranged from 3 to 3,2 minutes, and the eluate was analyzed by UV-VIS detector. A linear response was found for the acrylamide standard tested within the concentration range of 0,8 – 10µg/ml and the corelation coefficient (r) greater than 0,999, with detection limit 0,06 ppm and quantitative limit 0,19 ppm. Sample preparation was performed by means of solvent extraction using dichlormethane and subsequent re-extraction of the organic solvent with water. This aqueous sample solution was found to be free of any interferences and gave acrylamide and recorveries higher than 90%.
