Abstract

Inflammation is a natural respon for tissue damage. To reduce inflammation, people used a NSAID (Non Steroid Antiinflammatory Drugs). This agent caused many side effects. One of medicinal plant empirically used for traditional medicine is Piper Crocatum Ruiz & Pav. This plant is potential to be developed as medicine for anti-inflammatory because its contains flavonoid, saponin, tannin, and alkaloid. The aim of this study was to investigate the anti-inflammatory effect of the P.Crocatum extract  using carrageenan-induced rat oedema test. For the anti-inflammatory activity measurement, five different groups were established and piper extract was administered  in three different doses : 25, 50 and 100 mg/kgBW. Acetosal was used as a reference agent. It was found that reduction in the flammation was 77.58% for acetosal,  72.37% for 25 mg/kg extract, 85.60% for 50mg/kg, and 81.02% mg/kg for 100mg/kg extract. Extract of P. Crocatum at 50 mg/kg showed the strongest anti-inflammatory activity among the doses used. The results showed that P. Crocatum extract posseses promising anti-inflammatory effect.

Abstract

The use of cassava starch for excipient in the manufacturing of the tablet has some problems, especially on physical-mechanical properties. The purpose of this study was to determine the effect of the differentness of temperature and pH in the process of modification on the physical-mechanical properties of modified cassava starch. Modifications were performed by suspending cassava starch into a solution of 3 % (w/v) PVP K30. The effect of the difference of temperature was observed at temperatures of 25; 45 and 65 0C, while the effect of the difference of pH was observed at pH of 4.0; 7.0 and 12.0. The results showed that the temperature and pH did not affect the physical-mechanical properties of the modified cassava starch. Modification of cassava starch at pH and temperature of 7.0 and 45 0C was produced modified cassava starch with the most excellent solubility, while the best swelling power were formed by the modification process at pH and temperature of 7.0 and 25 0C. Overall, the most excellent compression properties of modified cassava starch resulted from the modification process at pH 12.
