This study aims to determine the effect of processing methods on antioxidant activity and characteristics of African leaf herbal tea and find out the right processing method to get the highest antioxidant activity and the best characteristics. The Completely Randomized Design was used in this study with treatment methods which consisted of 4 levels, namely Method A (steam blanching and drying), Method B (withering and pan firing) Method C (withering and Drying) and Method D (steam blanching and pan firing). This study was repeated 4 times to obtain 16 experimental units. The data obtained were analyzed by analysis of variance and if the treatment had a significant effect it was followed by Duncan’s Multiple Range Test (DMRT). The parameters tested in this study include water content, ash content, total phenols, total flavonoids, color, antioxidant activity and sensory characteristics. The results showed that the methods of processing herbal tea powder of African leaves has a highly significant effect on water content, total phenol, total flavonoids, antioxidant activity, color, and sensory tests of color, taste, flavor and have a significant effect on overall reception and have no significant effect on ash content. Herbal tea powder of African leaves processed by method steaming and drying was the best treatment with a moisture content of 6.41%, ash content of 5.27%, total phenol of 2.4169 mgGAE/g, total flavonoids 2, 6563 mgQE/g, antioxidant activity 67.28%, color (L, a, b = 4.86; -49.07; 34.71), light green color, very distinctive aroma of African tea leaves, very bitter taste, and overall reception likes.

Kenikir is a plant easily found in Indonesia. Kenikir leaves contain high levels of antioxidants, phenols, flavonoids, and vitamin C that kenikir leaves can be used as tea. This study aims to determine the effect of drying temperature and particle size on the content of bioactive compound in kenikir herbal tea and to determine the right drying temperature and particle size in order to produce the best characteristics of kenikir herbal tea. This experiment used a group factorial randomized design with two factors. The first factor was drying temperature which consisted of 50 ± 2 °C, 60 ± 2 °C, and 70 ± 2 °C. The second factor was the particle size consisted of 40, 60, and 80 mesh. The variables observed in this study were total phenols, total flavonoids, vitamin C and antioxidants. The data obtained were analyzed by analysis of variation (ANOVA) and analysis with real difference test (tukey) using Minitab 16 software. The results showed that the interaction between drying temperature and particle size had a very significant effect on total phenolics, total flavonoids, total vitamin C and antioxidant activity of kenikir herbal tea. The best treatment to produce kenikir leaf herbal tea was at a drying temperature of 70 ° C and a particle size of 80 mesh, with characteristics total phenol of 83.85 ± 0.12 mg GAE / g, total flavonoids of 7.25 ± 0.12 mg QAE / g, vitamin C 2.05 ± 027 mg / g and antioxidant activity (IC50) of 157.87 ± 0.08 ppm.

This research was to determine the effect of type of solvent and the ratio of material to the solvent with ultrasonication on antioxidant activity of beluntas leaf extract (Pluchea indica Less) and also determine the right type of solvent and the ratio of material to the solvent to extract beluntas leaves with the highest antioxidant activity. The complately Randomized Design (CRD) with 2 factors was used in this study. First factor is the types of solvents with 4 level (aquades, methanol 90%, ethanol 90%, acetone 90%) and second factor is the ratio of materials to solvent with 3 level (1:10, 1:15, 1:20). The treatment were repeated twice for obtain 24 experimental units. Variables observed were yield, total flavonoids, total tannin, antioxidant activity and IC50. The data were analyzed using variance and if the treatment had a significant effect, on was followed by the Duncan Multiple Range Test. The results showed that the interaction between the types of solvents and the ratio of material to the solvent had a very significant effect (P <0.01) on yield, total flavonoids, antioxidant activity, IC50, but the interaction have no real effect on the total tannin only show the very significant effect against solvent type and ratio on total tannin. The results showed that ethanol 90% with a ratio of 1:20 was the best treatment that produced antioxidant activity of 67.03 %, IC50 of 74.37 ppm, total flavonoid of 11.08 mg QE/g, total tannin of 7.78 mg TAE/g and  yield of  4.16%.
