Introduction: Some plants that have good efficacy for treatment is green tea, red ginger and centella. Stimulantia effectiveness the combination of extract was test with natatory exhaustion and continued by the formulation in lozenges. Methods: Have done stimulatia effectiveness test a lozenges containing the active ingridient of green tea, red ginger and centella use a mice with natatory exhaustion method. Results: The lozenges has a good effectiveness of increasing the stamina with the average result of the test 17 minutes 1 second. Conclusion: Based on the activity assay, the use of lozenges that shows result equivalent to the positive control (caffein) is use 3 times a day.

Objective: Test the antioxidant activity of banana peel extract, watermelon rind extract, and combinations, also in lotion dosage form. Methods:The antioxidant activity of each extract and their combinations were tested with 2,2-diphenyl-1-picrylhydrazil method and formulated into a lotion dosage forms. Evaluation of the lotion dosage forms, including organoleptic, homogeneity, pH, viscosity and rheology, microbiology, acute dermal irritation test, as well as the antioxidant activity test.Results: Antioxidant activity test on the extract showed inhibitory concentration 50% (IC 50 Conclusion:Lotion dosage form formula that meets the requirements of quality, efficacy, and safety with the best antioxidant activity is lotion dosage form combination of banana peel and watermelon rind extract formula (IC 75 :IC 25 ).

“…This procedure was firstly presented by Bratchell (1989) and latter demonstrated by Ellekjaer et al (1996) and Ribeiro et al (2010). Although several statistical experimental design investigations involving natural antioxidants for the shelf life extension of vegetable oils can be found in literature (Kochhar and Rossell 1990;Jaswir and Man 1999;Hras et al 2000;Jaswir et al 2000), examples of optimization where simultaneous PCA and RSM approach to develop a synergistic blend of SAG and AP have not been undertaken. Through this work, we have attempted to evaluate the methodology by combining the PCA-RSM using central composite rotatable design (CCRD) to minimize the complexity analysis of several dependent variables.…”

“…SAG is good source of primary antioxidants, which mainly possess radical scavenging and reducing capacity, whereas citric acid (CA) and ascorbyl palmitate (AP) are secondary antioxidants, which primarily act as chelating agent and oxygen scavengers, respectively (Kochhar and Rossell 1990). The synergistic effects of natural antioxidants in enhancing the oxidative stability of sunflower oil (SO) have been previously…”

The simultaneous optimization of a synergistic blend of oleoresin sage (SAG) and ascorbyl palmitate (AP) in sunflower oil (SO) was performed using central composite and rotatable design coupled with principal component analysis (PCA) and response surface methodology (RSM). The physicochemical parameters viz., peroxide value, anisidine value, free fatty acids, induction period, total polar matter, antioxidant capacity and conjugated diene value were considered as response variables. PCA reduced the original set of correlated responses to few uncorrelated principal components (PC). The PC1 (eigen value, 5.78; data variance explained, 82.53 %) was selected for optimization using RSM. The quadratic model adequately described the data (R 2 = 0. 91, p < 0.05) and lack of fit was insignificant (p > 0.05). The contour plot of PC 1 score indicated the optimal synergistic combination of 1289.19 and 218.06 ppm for SAG and AP, respectively. This combination of SAG and AP resulted in shelf life of 320 days at 25°C estimated using linear shelf life prediction model. In conclusion, the versatility of PCA-RSM approach has resulted in an easy interpretation in multiple response optimizations. This approach can be considered as a useful guide to develop new oil blends stabilized with food additives from natural sources.
