The cortex of jackfruit (Artocarpus heterophyllus) contains some flavonoids which have activity as tyrosinase inhibitors. This compound can inhibit the oxidation of l-tyrosine and levodopa in the mechanism of melanogenesis. The extract of jackfruit cortex formulated into creams differentiated by the extract concentration of 1,5% and 2,0%. Physical stability test was conducted with storing the creams at three different temperatures, 7 ± 2°, 27 ± 2°, and 40±2°C respectively. Centrifugal tests and cycling test was also performed on both cream. Tyrosinase inhibitory activity measurement was done by in vitro studies with measuring dopachrome. The result showed that both of formulations which stored at 40±2°C and centrifugated at 3800 rpm for 5 hours were not stable. The result of tyrosinase inhibiton activity measurement of creams containing extract of 1,5% and 2,0 % were 10,64% and 11,34%, respectively. Tyrosinase inhibition activity of creams decreased after two month stored. Tyrosinase inhibition activity of cream containing 1,5%extract decreased into 6,93%, and cream containing 2,0%extract decreased into 7,74%. The decreasing of tyrosinase inhibition activity is caused by the small amount of antioxidant is not enough to prevent oxidation of active ingredient.

Anticellulite topical gel preparation with caffeine as active ingredient needs a penetration enhancer to reach subcutaneous layer. Sodium hyaluronate (NaHA), the sodium salt of hyaluronic acid, is a hydrophilic polysaccharide derivative polymer. It has ability to enhance percutaneous penetration by loosening the dense of the compact substance stratum corneum. The aim of this research was to observe the effects of NaHA on caffeine penetration as anticellulite active agent in three types of gel preparation: hydrogel, hydroalcoholic gel, and gel emulsion. Each gel type contained caffeine 1,5% and was varied into three formulas. Formula 1 contained HPMC 2% as gel basis; formula 2 contained HPMC 2% and NaHA 0,5%; formula 3 contained NaHA 2% as gel basis. Caffeine penetration properties were analyzed by Franz diffusion cell in vitro test using rat skin as membrane. Percent caffeine penetration of hydrogel formula 1, 2, 3 were 9,41 ± 0,01%; 11,74 ± 0,13%; 16,32 ± 0,03%, respectively. Percent caffeine penetration of hydroalcoholic gel formula 1, 2, 3 were 19,54 ± 0,02%; 22,99 ± 0,23%; 7,42 ± 0,08%, respectively. Percent caffeine penetration of gel emulsion formula 1, 2, 3 were 10,47 ± 0,19%; 13,41 ± 0,12%; 18,42 ± 0,06%, respectively. The result showed that NaHA enhanced the caffeine percutaneous penetration properties in various gel preparations, except hidroalkoholic gel formula 3.

The Development of a Computer Simulation Software as a Tool in Pharmacokinetics Analisys. This research uses mammilary model (one compartment and two compartments) as compartment model in which a single drug administration is given via oral and intravenous. Mathematical modeling in differential equations can be derived from a pharmacokinetics model. The solutions are pharmacokinetics variables and parameters that can be solved using some mathematical and numerical methods such as Laplace transformation, residual method, superposition principle, trapezoidal rule and some solving methods in differential equations.To overcome manual calculation and to visualize a drug’s dynamics in the graph form, a computer simulation software based on Visual Basic has been built. The simulation results show that any particular sample data plasma can be checked whether it is given orally or injection and has a tendency to be compatible with an assumption of one compartment or two compartments. For urin data, the software capability is still limited only for one compartment. However, it can checked if the corresponding data is given via oral or injection. So the simulations show that pharmacokinetics variables and parameters will have individual effects

Rosella, also known as Hibiscus sabdariffa L., is a plant that contains anthocyanin compounds in its calyx, which are known for their antioxidant properties. These compounds give the plant a captivating red color and can be used as natural dyes. This study aimed to exploit anthocyanins in rosella calyx as natural dyes and antioxidants in lip cream product. The formulations employed extracts from rosella calyx, a viscous extract from maceration in 96% ethanol (F1) and a commercially available powdered rosella extract (F2). Evaluation on the formulations demonstrated that both F1 and F2 effectively maintained the color integrity of the lip cream. Moreover, an irritation test among 10 respondents showed no adverse reactions. Additionally, a hedonic test of 30 respondents revealed uniformity in homogeneity, odor, and spreadability on both formulations. However, a noticeable contrast emerged in color intensity, with F2 exhibiting greater intensity and preference over F1. The rosella calyx extract also demonstrated its antioxidant potential with an IC50 value of 130.11 ± 2.08 µg/ml. The study highlights the utility of rosella calyx extracts as a dual-functioning component in lip cosmetics. The findings indicate the variations in formulation efficacy and color intensity, emphasizing the potential of rosella-derived extracts in developing cosmetics with enhanced aesthetic appeal and functional antioxidant attributes.

Saponin is a group of compounds contained in natural materials that have amphiphilic properties and can reduce surface tension. The reduction of surface tension caused by a soap compound (Latin = sapo) that can disrupt hydrogen bonds in water. Red frangipani plant (Plumeria rubra) is known to have saponin content. The research objectives were to identify the saponin content of red frangipani plant extract (Plumeria rubra) which could reduce the surface tension. Part of red frangipani plant (flowers, leaves and stems) was extracted using five kinds of solvents. Each of the extracts obtained was then tested for saponin content qualitatively. Extract from each part of the plant (flower, leaf, and stem) which has the highest foam was selected then tested surface tension using surface tensionmat equipment. The result of qualitative saponin test showed that flower, stem and flower extract of red frangipani with aqua demineralisata solvent had the highest saponin content compared to extract with other solvent. The content of saponins in plumeria rubra extract either from the leaves, stems or flowers could decrease the surface tension with the best results obtained from the flower extract with 8,61% of Critical Micelle Concentration (CMC).
