Abstract

Celery is an Indonesian herb being used as vegetable and medicinal purposes especially in hypotensive remedy. In order to produce a good quality of celery herb extract granules, a study on the influence of spray rate, level of lactose and Aerosil in fluidized bed granulator (FBG) toward homogeneity, flow rate and water content of granules was done.In the optimization process was programmed by factorial design, the maximum spray rate was 4 L/hours and the minimum was 2 L/hours, the maximum amount lactose was 100% and the minimum was 80% of extract weight, and Aerosil content maximal 20% and minimal 0% of extract weight. The optimum area of optimization result was found from superimposed contour plot granule parameters including homogeneity of apiin content, flow rate and moisture content of granules.The result showed that the Aerosil was proven to be disadvantageous in FBG process. The optimum area of optimization to obtain good granules was achieved by 2.75 L/hour to 2.00 1/hour of spray rate with the amount of lactose at 93.5% to 100% of extract weight with viscosity at 2.8 cP and density at 1.07 g/mL and without Aerosil. The granules possesed homogeneity of apiin with CV 3-5%, 0.85-1.00% of water content and 12.0-13.0 g/sec of flow rate.Key words: Celery (Apium graveolens L.), apiin, factorial design, extract, granules.

Abstract

Inflammation is the response of living tissues caused by injury. It involves a complex battery of enzyme activation, mediator release, extravasation of fluid, cell migration, tissue breakdown and repair. Inflammation mediator is synthesized in the body by several steps and catalyzed by several enzymes, such as cyclooxygenase and class- glutathione S-transferases (GSTs) in the cyclooxygenase arachidonic acid cascade. Aspirin, which has been reported as an inhibitor to inflammation mediator synthesis in the cyclooxygenase arachidonic acid cascade, is a non-steroid anti-inflammatory agent. The aim of this research is to study the effect of aspirin on rat liver class- GST activity in vitro. GSTs were isolated from the rat liver cytosolic fraction by centrifugation according to Lundgren. Protein concentration in the cytosol was determined spectrophotometrically using bovine serum albumin as a standard. The GST activity was determined using conjugation reaction rate between glutathione (GSH) and 1,2-dichloro-4-nitrobenzene (DCNB), followed by determining IC50 of aspirin. Then, a study was done to determine the ability of aspirin in inhibition of the rat liver class- GST activity in vitro. It can be concluded that aspirin has no inhibitory effect on rat liver class- GST activity.Key word: Aspirin, anti-inflammatory, glutathione S-transferase.
