Abstract

It has been proven that gotu kola (Centella asiatica (L.) Urban) have an antioxidant activity that make it possible to use in preventing degenerative illness. The aims of this study are to find the effect of n-hexane purification before maceration on asiaticoside content, free radical scavenging activity and total phenolic content of gotu kola ethanolic extract. The gotu kola extract was made by maceration process using the mix of ethanol and aquadest as solvents in different proportion, which are 100%:0% (E100), 75%:25% (E75), 50%:50% (E50), 25%:75% (E25), and 0%:100% (E0). The determination of asiaticoside content in gotu kola ethanolic extract was measured using Thin Layer Chromatography (TLC) Densitometry method, free radical scavenging activity was measured using diphenylpicryl hydrazyl (DPPH) and defined by parameter of IC , and total phenolic content was defined by equivalency of galic acid using Folin-Ciocalteau. The results show that the hexane purification would increasing total phenolic content significantly in ethanolic extract which extracted with solvents in proportion of ethanol:aquades 75%:25% (E75), 50%:50% (E50), and 25%:75% (E25), but not significant in decreasing of IC . Statistically, n-hexane purification was also not significant to increasing asiaticoside content in gotu kola ethanolic extract.

Abstract

It has been proven that Centella asiatica (L.) Urb. herbs have an antioxidant activity that make it possible to used in preventing degenerative illness. Centella asiatica (L.) extract has been formulated to fast disintegrating tablet (FDT) dosage form. The aims of this study are to find the optimum formula of FDT of Centella asiatica (L.) Urb. The simplex lattice design method with 3 factors (which are mannitol as diluents, crospovidone as superdisintegrant and povidone as binder) and 2 levels of each was used. Centella asiatica (L.) Urb. extract was produce from maceration process using ethanol-water in ratio 75%:25% as a solvent. Direct compress method was used to produce the FDT. The results show that the optimum composition between excipients FDT formula could be reached, which fullfiled the physical properties parameter which are the hardness, friability and disintegration time of FDT.
