Abstract

Studied the characteristics of natural zeolite catalysts activated and modifications and catalytic activity in the isomerization of glucose. Natural zeolite was activated by NH4NO3 2 M obtained catalyst HZA. While modification using 0,24 M Sn metal impregnated on HZA obtained catalyst Sn-HZA. At this stage, hydrothermal process carried out at temperature of 90 °C for 12 hours followed by calcination at temperature of 500 °C for 4 hours. The characterization includes the XRD analysis, SEM-EDAX analysis, acidity by ammonia method, and surface area by adsorption of methylene blue method. Glucose conversion was obtained through analysis of polarimeter at hour-0, 1, 2, 3, and 4 with temperature variation of 110, 120, and 130 °C. Solution which had the highest conversion resulted by polarimeter was analyzed by HPLC. XRD analysis showed that there were no changes in the structure of zeolite after activation and modification process. SEM-EDAX analysis showed that morphology of the zeolite surface is not damaged and Sn metal was successfully impregnated 6,94 %. The activity of HZA and Sn-HZA was 1,4850 mmol/g and 2,3145 mmol/g. while the surface area of HZA and Sn-HZA was 11,4077 m2/g and 11,4738 m2/g. Using the Sn-HZA catalyst with the reaction temperature of 120 °C provides the highest conversion of glucose and fructose selectivity. It were 14,0733 % w/v and 0,646 % w/v.   Keywords: Catalyst, glucose, isomerization, natural zeolite, Sn metal.

Abstract

Bamboo grass (Lophatherum gracile B.) is one of weed plants which frequently used as a medicine because it provides active compounds, for instance steroids and tannins. This research was conducted to determine the anticancer activity of extracts and fractions of leaves bamboo grass in inhibiting the growth of breast cancer cells T47D, and to determine the class of the active compounds contained in extracts and fractions which have the lowest IC50 value from phytochemical test and identification with UV-Vis instruments and FTIR. The extraction of active compound leaves of bamboo grass is done by maceration method using ethanol 80%, hydrolysis and partition with n-hexane and chloroform. Four of the extracts is phytochemical tested and anticancer activity tested towards breast cancer cells T47D with MTT method. The best results of the test activities are performed by the separation of classes of active compounds KLTP and are identified using UV-Vis spectrophotometer and FTIR. The value of IC50 from 80% ethanol extraction is 321,389, from hydrolysis extraction is 481.984, from the fraction of chloroform is 177.852, and from n-hexane fraction is 300.681 µg / mL. The lowest IC50 which have the best cytotoxic is the fraction of chloroform and n-hexane. The results of phytochemical test fractions of chloroform and n-hexane fraction indicates the tannin and steroids. The identification result by using UV-Vis and FTIR shows that the fraction of chloroform and n-hexane fraction is containing tannin, which isproven by maximum wavelength at 331.6 nm and 331.6 nm allegations of -OH, CH, C=C. Moreover, the existence of steroid compounds in fraction chloroform and n-hexane is shown by the absorption at 279.1 nm and 278.0 nm of wavelength with allegations of -OH, CH, C=C, C-O.

Abstract

The  aims  of  this  research was to identify the flavonoid content in binahong tuber and determine the effect of 70 % ethanol extract of binahong tuber on blood glucose level and SOD activity in rats (Rattus norvegicus) induced alloxan. The extract was maceration and then used to test the classes of its compound content using phytochemical test, the flavonoid compound contained in the extract was separated by analytic thin layer chromatography (TLC) and antidiabetic effect against rats induced alloxan with dose of alloxan was 32 mg / 200 g BW. The results showed that the 70 % ethanol extract of binahong tuber contains flavonoids, alkaloids, tannins, saponins and terpenoids. Butanol: acetic acid: water (4: 1: 5) was the best eluent for separation of flavonoid compound in extract and binahong tuber extracts treatment with variation of extract dose, 25, 60 and 75 mg/kg BW, reduced the blood glucose levels and increased the SOD (Superoxide dismutase) activity of rat, that are 5,511 ; 5,217 and 4,942 u/mL respectively. Keywords: alloxan, antidiabetic, flavonoids, binahong tubers, SOD

Abstract

The high protein content in rice bran potential to be developed into food. The purpose of this study was to isolate the protein in rice bran using NaOH solution with various concentration of 0.05; 0.1; 0.15; 0.2 M and characterization of functional properties. The results showed the concentration of 0.2 M NaOH produced the best results. The protein content obtained was 82%, stability of  emulsion of 42% and 47% stabilty of foam. Keywords: NaOH, protein, rice bran
