AbstractThe main purpose of this study was to determine the chemical composition of monofloral bee-collected pollen from the coffee (Coffea robusta) plant and its pellet morphology. According to the results coffee bee pollen (CBP) has a high nutritional value. It contains a large percentage of protein, reducing sugar, and lipid. Also, vitamins (B2 and E) and minerals (K, Ca, and P) were found in CBP. In addition, the results revealed that the total polyphenols content (TPC) was 10.62 mg GAE/g dry weight (DW) and antioxidant activity (AA) of CBP was 5.52 μmol TE/g DW. Some physical properties of CBP pellet were recorded such as moisture, relative diameter, sphericity, bulk density, and colour parameters. The pollen pellet exhibits shapes of colour from light to dark yellow. These results pointed out that CBP can be used as a remarkable source of compounds with antioxidant activity and health-protective capacity for humans.

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.

Damaged skin due to free radicals from ultraviolet radiation can be prevented using antioxidants. Red dragon fruit (Hylocereus polyrhizus) containing antioxidants can be made into a peel off gel face mask using gelatin as a gelling agent to be applied easily to the skin. The purpose of this study is to determine the effect of various gelatin concentrations on the physical properties and antioxidant activity of peel off gels containing red dragon fruit juice. The peel off gels face mask were made using various gelatin concentration i.e 7.5% w/w (F1); 10% w/w (F2); and 12.5% w/w and containing 10% w/w red dragon fruit. The peel off gels then evaluated for physical properties and antioxidant activity using DPPH. The result showed that the increasing of the gelatin concentration would increase the drying time and adhesive ability of the peel off gels. The escalation of gelatin concentration from 7.5% w/w (F1) to 10% w/w (F2) did not affect the spreading ability of the peel off gel. However, the spreading ability of the peel off gel decreased with the increasing concentration of gelatin from 10% w/w (F2) to 12.5% w/w (F3). The antioxidant test of peel off gel had an average percentage of inhibition of 9.101% (F1); 12.469% (F2); and 15.109% (F3). Based on the results of physical properties and antioxidant activity showed that formula 2 was recomended.

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.
