Sterculia populifolia is commonly used as the ingredient of traditional herb in Timor Island, East Nusa Tenggara, Indonesia. It contains flavonoid which roles as antioxidant. This flavonoid can be sunblock due to the existence of chromophore which commonly gives color to plants. This study aimed to determine the activity of antioxidants and sunblock through the value of Sun Protection Factor (SPF) from Sterculia populifolia extract-based cream and cream preparation extract. This cream was formulated into four formulas; extract concentrate 0% (F0), 1% (F1), 3% (F2) and 5% (F3). The result showed that the whole formula of cream preparation filled the physical stability parameter. F3 cream had IC50 79.179 ppm value while SPF had 5.6 value higher than F1 and F2. The smaller the IC50 value, the bigger antioxidant activity and SPF increased.

Moringa leaves are one part of the plant which has many health properties one of which is an antioxidant. One of the content of Moringa leaves which contains antioxidant activity is quercetin. Quercetin Is polar and insoluble in air. An experimental research method with a descriptive analysis design, starting with making Moringa leaf maserat, screening, and testing the SPF value, using a UV-Vis spectrophotometer. The purpose of this research was to find out the type of solvent against the SPF value of Moringa leaf maserat. Based on the experiments that have been carried out the methanol (6.75) solvent elds a higher SPF value compared to ethanol (5.32).   Keyword: Moringa Leaf, Solvent, SPF. ABSTRAK   Daun kelor merupakan salah satu bagian tanaman yang memiki banyak khasiat untuk kesehatan salah satunya ialah sebagai antioksidan.

Endophytic fungus RS3 isolated from coastal plant sarang semut (Hydnophytum formicarum) produced extracellular black pigment. The aims of this research were to obtain the pigment, to characterize and to determine the photoprotector activity. This research was conducted into several steps, that were determination of the best precipitating agent, characterization using instrument and solubility analysis, and analysis of Sun Protection Factor (SPF). Results showed the pigment was precipitated using acid solvent with pH ≤ 2.5. Functional groups of pigment were hydroxyl, aromatic ring, phenol and amine. According to its characteristics, black pigment produced by RS3 isolate was proposed as melanin. The photoprotector analysis showed the SPF value was 11.33.

Background: Schinus molle L. is a medicinal and aromatic plant widely used in folk medicine commonly found in Algeria and Mediterranean region. In the present work, we investigated the in vitro antioxidant, anti-cholinesterase, αglucosidase inhibitory and photoprotective potentials of the Schinus molle L. plant’s extract/fractions. The metabolite profile of Schinus molle L. was analyzed using RP-HPLC and GC-MS. Methods: Antioxidant activity was assessed using different tests. Anticholinesterase activity was investigated by quantifying the acetylcholinesterase and butyrylcholinesterase inhibitory activities. Antidiabetic activity was investigated by αglucosidase inhibition test, whereas photoprotective activity was evaluated by sun protection factor (SPF) using spectrophotometry UV-Vis. The extracts were then submitted to RP-HPLC–PDA and GC–MS analysis. Results: Ethyl acetate and buthanol fractions with high contents of total phenolics and flavonoids exhibited the strongest antioxidant activity. Ethyl acetate extract exhibited considerable enzyme inhibition potential on acetylcholinesterase, butyrylcholinesterase and α-glucosidase with percentages of inhibition of 99.08 ± 0.79 %, 100 % and 98.80 ± 0.18 % respectively. Furthermore, the ethyl acetate fraction showed high photoprotective activity with the sun protection factor (SPF) value = 38,26 ± 0.73. Three phenolic acids (gallic, tannic and vanillic acids) and five flavonoids (myricetin, apigenin, naringenin, rutin and quercetin) were identified with RP-HPLC–PDA. Conclusion: These findings suggest that Schinus molle L. may be useful in the development of an alternative agent for oxidative stress, Alzheimer’s disease, diabetes and could be used as a natural sunscreen in pharmaceutics or cosmetic formulations.

Purpose: To evaluate the correlation between sun protection factor (SPF) and the content of phenol and flavonoid and antioxidant activity. Methods: Different parts of 9 medicinal plants were extracted with methanol using three extraction methods (percolation, Soxhlet and ultrasonically assisted extraction) to obtain 42 crude extracts. Their phenol and flavonoid contents, and antioxidant activities were determined using Folin-Ciocalteu reagent, aluminum chloride method and DPPH radical-scavenging activity, respectively. The SPF values were determined and correlated with the phenol and flavonoid contents as well as antioxidant activities. Results: The phenol and flavonoid contents, and antioxidant activities ranged from 54.16-688.97mg GAE/g, 13.38-146.60 mg QE/g and 9.5-1472.4 µg/mL, respectively while the SPFs were between 0.067 and 0.841. The highest SPF was related to Cucumis melo L. ultrasonically assisted leaf extract (0.841) and Artemisia absinthium L., aerial parts extracted with percolation method (0.717). A significant correlation was found between SPF and phenolic (p= 0.003) and flavonoid contents (p= 0.023). Conclusion: This study showed a correlation between SPF and phenolic and flavonoid contents. Ultrasonically assisted extract of C. melo leaf has suitable SPF and can be used in sun screen formulations.
