Abstract

Alstonia scholaris L. contains several compounds, which has been proven to be potential as skin protection by formulating in gel preparation. The aims of this study was to obtained the concentration of carbopol 940 and glycerol to produce an optimal gel preparation of Alstonia scholaris L. leaf extract. Simplex lattice design was used as optimization method with two independent variable, carbopol 940 (0.5%-2.5%) as gelling agent and glycerol (14%-16%) as humectant. There were 5 formulas carried out to physical properties evaluation: organoleptic, homogeneity, spreadability, pH, adhesion time and viscosity. The result showed that the prediction of optimal formula from SLD method with 1.67% carbopol 940 and 14.83% of glycerol. The physical properties of optimal formula was 5.206±0,125 of pH value; 28,768.24±4,608.11 cP of the viscosity value; 5.96±0,087 cm of spreadability value; and 55.146±1.174 seconds of adhesion. There was no significant difference of SLD prediction responses with observation respons.

Abstract

Tenggulun (Protium javanicum Burm.fil) has been traditionally used to treat various ailments such as cough, stomachache, diarrhea, inflammation and headache. The leaves have therapeutic roles in the treatment and prevention of illnesses acting as antibacterial, antidiabetic and antiinflammation agents. It is also reported that tenggulun leaves can be used for insecticides, cosmetics and food additives. This research aimed to determine antioxidant activity by reducing FRAP of the tenggulun leaves methanol extract using Trolox as the standard solution. The result showed that the tenggulun leaves extract contained secondary metabolites of flavonoid and polyphenolic. The extract showed the FRAP reducing activity at 0,008634±0.00043 μmol TE/g DW. These results indicated the ability of tenggulun methanolic extract to reduce Fe (III) into Fe (II) equivalent to Trolox by the presence of secondary metabolites confirmed.
