Indonesia merupakan negara beriklim tropis dimana sangat memungkinkan kulit untuk terus terpapar sinar matahari. Radikal bebas berupa sinar ultraviolet dari matahari yang berlebih akan menyebabkan kerusakan pada kulit. Penggunaan lotion yang mengandung antioksidan dapat dilakukan untuk melindungi kulit dari paparan radikal bebas. Daun jambu air (Syzygium aqueum) merupakan salah satu tumbuhan yang memiliki aktivitas antioksidan. Senyawa myricetin dalam tanaman jambu air memiliki aktivitas sebagai UV protektor. Daun jambu air diekstraksi menggunakan pelarut etanol 96% dengan metode maserasi. Pengujian aktivitas antioksidan dilakukan menggunakan metode DPPH dengan vitamin C sebagai pembanding. Pengujian nilai SPF dilakukan menggunakan spektrofotometri UV-Vis yang didasarkan pada persamaan Mansur. Lotion Ekstrak etanol daun jambu air dilakukan pengujian aktivitas antioksidan, nilai SPF dan evaluasi organoleptik, homogenitas, pH, daya sebar dan daya lekat selama 4 minggu.  Hasil menunjukkan bahwa Ekstrak dan sediaan lotion ekstrak etanol daun jambu air (Syzygium aqueum) memiliki aktivitas antioksidan sangat kuat dan sedang, sedangkan nilai SPF-nya  termasuk kedalam kategori proteksi ultra dan maksimal.

Penelitian ini bertujuan untuk menguji aktivitas perlindungan tabir surya dari ekstrak etanol kulit buah, kulit biji dan biji pinang yaki secara in vitro. Tahap pendahuluan penelitian ini yaitu menguji nilai SPF (Sun Protection Factor) yang dilakukan secara invitro dengan menggunakan metode spektrofotometri UV-Vis. Serbuk kulit buah, kulit biji dan biji dimeserasi dengan pelarut etanol kemudian dipekatkan dengan rotary evaporator sehingga menghasilkan ekstrak pekat. Ekstrak etanol kulit buah, kulit biji dan biji pinang yaki memiliki nilai SPF yang berbeda yaitu 12,05 , 3,45 , dan 1,00. Dari nilai SPF ketiga sampel tersebut, kulit buah yang memiliki nilai SPF tertinggi dan termasuk dalam kategori Proteksi Maksimum sehingga kulit buah pinang yaki dapat dilakukan uji lanjut tentang aktivitas perlindungan tabir surya secara in vivo.The purpose of this study were to test the sunscreen protection activity of ethanol extract of the skin of Pinang Yaki fruit, shell skin and seed by using in vitro method. The preliminary stage of this research was to test the value of SPF (Sun Protection Factor) by invitro using UV-Vis spectrophotometry method. Skin of Pinang Yaki Fruit, shell skin and seed were maceration with ethanol then concentrated with a rotary evaporator to produce a concentrated extract. Skin of Pinang fruit, shell skin and seed have different SPF values of 12.05, 3.45, and 1.00. From the SPF values of the three samples, the skin of the fruit has the highest SPF value and is included in the Maximum Protection category so that the skin of Pinang Yaki fruit could be tested futher for  sunscreen protection activity by in vivo method.

One way that is done to reduce the negative impact of sunlight is by using sunscreen. Sunscreen can protect the skin by spreading sunlight or absorbing sunlight radiation energy that is about the skin. Phenolic compounds especially flavonoid groups have the potential as a sunscreen because of the chromophore group (single conjugated double bond) capable of absorbing UV light both UV A and UV B, thus reducing the intensity of the skin. Flavonoids have three properties of photoprotektor that is UV absorption, antioxidant properties, and modulate some DNA signaling pathways. The potential of sunscreen can be expressed with Sun Protection Factor (SPF). SPF is designated as UV protection B and is not specifically intended to resist UV A and UV C. The purpose of this research is to know the value of SPF (Sun Protection Factor) of ethyl acetate extract of mango gedong leaves using UV-Vis spectrophotometry. Simplicia gedong mango leaves were extracted using ethyl acetate solvent by reflux. Gedong mango leaf extract identified flavonoid compound using 10% NaOH and H2SO4 (concentrated). Determination of SPF (Sun Protection Factor) value of med gedong leaf extract using UV-Vis spectrophotometry method. The concentration of ethyl acetate extract of mango gedong leaves used was 120 ppm, 240 ppm and 360 ppm. The SPF (Sun Protection Factor) values were analyzed using Mansur method. The result of identification of flavonoid compound showed that the extract of ethyl acetate of mango gedong leaves positively contain flavonoids, while the result of SPF (Sun Protection Factor) extract of ethyl acetate of mango gedong leaves was 5,556; 16,675 and 22,243. The SPF (Sun Protection Factor) extract of 5,556 muddy ethyl acetate leaves including moderate protection type, 16,675 and 22,243 including ultra-protection type when tested using UV-Vis spectrophotometry by Mansur method

Objective: The aim of the present work is to investigate the presence of ultraviolet (UV) light absorption capacity of the selected plant extracts. Chemical-based sunscreens provide protection against the sun’s rays, in particular, UV radiation. Sometimes, exposure to these chemicals leads to allergies to the skin. The best way to protect skin from chemical and photoallergies is to use plant-based creams and lotions.Methods: Methanol and water extracts of Datura metel leaves and flowers; Loranthus leaves and flowers; and Eucalyptus leaves were prepared and checked their UV absorption ability from 200 nm to 450 nm. Different concentrations of the same extracts were tested for their sun protection factor (SPF) using Mansur formula from 290 to 320 nm. All the extracts showed absorption at UV range.Result: The calculated values of SPF were fallen in the range of 0.4–23.5. Among the three plants used in this study, methanol extract of Eucalyptus showed highest UV absorption than the other two plants. In vitro studies of a few phenolics from various plants have been found to be mutagenic. This might be the result of pro-oxidant than antioxidant action of these compounds. Keeping in view of human use as SPFs, it is indispensable to investigate the toxic effects of the extracts.Conclusion: The preliminary findings of this study reveal that the methanol extract of Eucalyptus has a high sun protection effect. This extract can be used as additives in other sunscreen formulations to enhance their SPF.
