Physical properties and optimization of bio film prepared with corn starch and Justicia adhatoda leaf extract

The exogenous carbohydrate (CHO) oxidation of naturally enriched [13C]CHO sources with different solubilities was studied during cycling exercise (150 min, 60% maximum work output). Moreover, the effect of adding a 13C tracer with different physical properties than the tracee on exogenous CHO oxidation was investigated. Test solutions (28.5 ml/kg body wt) were water for control of 13C background, 15% soluble partially hydrolyzed corn starch (SOL), 15% insoluble corn starch (In-SOL), and 15% InSOL with [13C6]glucose as tracer. Both the mean and peak exogenous oxidation rates were significantly greater (P < 0.05) in the SOL trial than in the InSOL trial (mean oxidation rate, 0.84 +/- 0.21 and 0.50 +/- 0.15 g/min, respectively; peak oxidation rate, 1.10 +/- 0.18 and 0.81 +/- 0.25 g/min, respectively). The amount of the ingested CHO that was oxidized was significantly higher (P < 0.05) in the SOL trial (126 +/- 31 g) than in the InSOL trial (75 +/- 25 g). When we added an extrinsic tracer ([13C]glucose), the apparent mean and peak oxidation rates of the trial with InSOL and [13C6]glucose were significantly (P < 0.05) higher (0.91 +/- 0.30 and 1.23 +/- 0.41, respectively) than the InSOL values. These results 1) indicate that the addition of the soluble [13C]glucose tracer to an insoluble starch tracee leads to overestimation of the exogenous CHO oxidation rates and 2) suggest that soluble CHO is oxidized at a higher rate during exercise than isocaloric insoluble CHO.

Objective: The purpose of this research was to determine antioxidant activity of green tea leaf extract, the value of sun protection factor (SPF),physical properties, and stability of green tea cream.Methods: Green tea leaf extract was obtained by maceration using 96% ethanol. Cream was prepared in three formulas with various concentrationof the green tea leaves extract. The physical evaluations included organoleptic, pH, viscosity, adhesion, spreadability, and stability tests weredone. The determination of the SPF value is calculated using the Mansur equation. Extract of green tea leaf has strong antioxidant activity(IC50 2.19 μg/ml).Results: The green tea leaf extract showed high antioxidant activity (2.19 μg/m). All formulas are organoleptically creamy brownish-green to brown,with a distinctive green tea odor and homogeneous. All formulas met the requirements of physical properties of cream. The creams showed significantchange while they were stored at 4°C and at 40±2°C, but showed no difference when they were stored ad 26°C. SPF values of cream are 0.54; 2.03,and 2.41, respectively.Conclusions: It is clearly indicated that the sunscreen cream of green tea leaf extract is potential to be further developed as cosmetic preparations.

Tahongai leaves (Kleinhovia hospita L.) is a medicinal plant that has antioxidant activity which is almost equivalent to vitamin C. The development of the dosage form to improve the utilization of these plants. Therefore Tahongai leaves made in the form Orally Disintegrating Tablets (ODT), which has several advantages such as more practical use because it can be consumed without the use of water and can be used by people who are hard to swallow capsules or tablets as well as having good taste in the mouth. This study was carried out experimentally using four formulas with various concentrations Explotab® ie; formula 1 (2%); formula 2 (4%); Formula 3 (6%) and the formula 4 (8%). The evaluation of ODT are uniformity of weight, hardness, friability and disintegration time.The results showed that the concentration Explotab® influence on the physical properties of ODT ie hardness, friability and disintegration time. Explotab® concentration of 4% is the best concentration that meets the requirements of the physical properties ODT Tahongai leaf extract.
