Potensi Antioksidan dan Tabir Surya Ekstrak dan Sediaan Krim Rambut Jagung (Zea mays L.)

Sunlight emits electromagnetic radiation consisting of infrared, visible light, and UV radiation. High sun exposure can have an impact on skin damage. Corn silk is a waste from the cultivation of corn crops whose utilization is still very limited. Corn silk extract contains phenolic, flavonoids, and carotenoids that are efficacious as antioxidants and sunscreens. This study aims to find out the potential of antioxidants and sunscreens in corn silk extract and cream. This study by reviewing 5 articles consisting of 1 international article and 4 accredited National articles that discuss the activity of antioxidants and sunscreens both extracts and corn silk cream (Zea mays L.) published in 2011-2021. The results of the study of the five articles show that the compounds contained in corn hair extract that have antioxidant activity and sunscreen are phenolic, flavonoid, and carotenoids. Corn hair extract (Zea mays L.) has a very strong antioxidant activity category and has activity as an ultra protection category sunscreen. Corn silk cream have a very weak antioxidant activity and have maximum protection sunscreen activity. Both of corn silk extract and cream have antioxidant and sunscreen activity in the presence of secondary metabolite compounds phenolic, flavonoid, and carotene. ABSTRAK Sinar matahari memancarkan radiasi elektromagnetik yang terdiri dari inframerah, cahaya tampak, dan radiasi sinar UV. Paparan sinar matahari yang tinggi dapat berdampak pada kerusakan kulit. Rambut jagung merupakan limbah hasil budidaya tanaman jagung yang pemanfaatannya masih sangat terbatas. Rambut jagung mengandung fenolik, flavonoid, dan karotenoid yang berkhasiat sebagai antioksidan dan tabir surya. Penelitian ini dilakukan untuk mengetahui potensi antioksidan dan tabir surya pada ekstrak dan krim rambut jagung. Penelitian ini dilakukan dengan mengkaji sebanyak 5 artikel yang terdiri dari 1 artikel Internasional dan 4 artikel Nasional terakreditasi yang membahas aktivitas antioksidan dan tabir surya baik ekstrak maupun dalam bentuk sediaan krim rambut jagung (Zea mays L.) yang dipublikasikan tahun 2011-2021. Hasil studi dari kelima artikel menunjukkan bahwa senyawa yang terkandung dalam ekstrak rambut jagung yang memiliki aktivitas antioksidan dan tabir surya adalah fenolik, flavonoid, dan karotenoid. Ekstrak rambut jagung (Zea mays L.) memiliki aktivitas antioksidan kategori sangat kuat dan memiliki aktivitas sebagai tabir surya kategori proteksi ultra. Sediaan krim rambut jagung memiliki aktivitas antioksidan kategori sangat lemah dan memiliki aktivitas tabir surya kategori proteksi maksimal. Ekstrak maupun sediaan krim rambut jagung memiliki aktivitas baik antioksidan maupun tabir surya dengan adanya kandungan senyawa metabolit sekunder fenolik, flavonoid, dan karoten.

Formulation of Gel from Corn Silk Extract (Stigma maydis) and Burns Healing Activity

Corn silk (Stigma maydis) contains compounds that play a role in wound healing, such as flavonoids, saponins, tannins. This study aims to formulate a gel from corn hair extract and see its activity in healing burns. The test group was divided into four groups: group I (hot metal induction), group II (without extract ), group III (corn hair extract concentration 5%), and group IV (comparison B®), which metal induction. The parameters observed were % wound healing, epithelialization time, and histopathology. The results of the study on the average% of burns healing rate 7, 14 and 21 days, namely group I (27,92%; 62,42%; 100%), group II (35,39%; 60,16%; 100%), group III (44,05%; 63,69%; 100%) and group IV (32,81%; 66,48%; 100%). The mean time of tissue peeling epithelialization groups I, II, and III was on day 16, and group IV was on day 17. For the histopathological results, the mean score of collagen fibers, fibroblast cells, and epithelialization was respectively group I (2,2; 2,7; 2), group II (2,8; 2,9; 2), group III (3,3; 2,9; 2,7), and Group IV (3,9; 3; 3). The results of the two-way ANOVA statistical test on % burn healing (p> 0.05) and one-way ANOVA at the time of epithelialization (p> 0.05) and the histopathological score (p <0.05) showed that group III (the corn hair extract 5 %) could influence the process of healing burns. Keywords: Burns, Corn Silk Extract (Stigma maydis), % Burn Healing, Epithelialization Time, Histopathology

TOPICAL APPLICATION OF Capsicum frutescens LEAF EXTRACT AS HAIR TONIC IN MICE (Mus musculus)

The research aims to determine the effect of giving cayenne leaf extract in increasing the length and amount of hair on mice. This research belongs to the type of quantitative research. This research used a Completely Randomized Design (CRD) in consisting of 5 treatment and 4 repetitions. The treatments consisted of NC (negative control, not treated), PC (positive control, given a commercial hair extract), P1 (cayenne leaf extract 10%), P2 (cayenne leaf extract 20%), and P3 (cayenne leaf extract 30%). Research parameters included the increase of the hair length and amount of hairs growing in mice. The result showed that giving extract of cayenne leaf significantly influences the length and amount of hairs in mice, with 10% concentration (P2) was the optimum concentration of the extract that can trigger the hair growth. It can be concluded that given extract of cayenne leaf can increase the hairs growth in mice and has potential as hair tonic.

Pengaruh Waktu Ekstraksi dan Konsentrasi Ekstrak Rambut Jagung (Corn Silk) Terhadap pH, Total Fenol Dan Aktivitas Antibakteri

<p>The growth of microorganisms in foodstuffs can lead to profitable changes such as nutritional improvements in food, digestibility or storage. In addition, the growth of microorganisms in food can also lead to undesirable physical and chemical changes, so the food is not worth consuming. Staphylococcus aureus and Escherichia coli are the bacteria that often cause infection in humans. To prevent this it is necessary to have bioactive components that can inhibit the growth of microorganisms. Active compounds such as saponins, triterpenoids, phenols, tannins, flavonoids and alkaloids are known to have antibacterial activity. Several studies have reported the chemical content found in corn hair. Corn hair is part of a corn plant that has not been used effectively because it is considered as waste. Based on research, corn hair contains proteins, vitamins, carbohydrates, calcium salts, potassium, magnesium, and sodium, essential oils, steroids such as sitosterol and stigmasterol, alkaloids, saponins, tannins, and flavonoids. So presumably corn hair extract has antibacterial activity.</p><p>This study aims to determine the effect of extraction time and concentration of corn hair extract on pH, total phenol and antibacterial activity.</p><p>The experimental design used in this study was Randomized Block Design (RBD) with 3 replications. The treatments used were Extraction Time A1 = 30 minutes, A2 = 40 minutes, A3 = 50 minutes and Concentration Extract (material: solvent) K1 = 75% (w / v), K2 = 50% (w / v), K3 = 25% (w / v). Furthermore, the data obtained were analyzed variant and if there was any difference between treatments followed by Duncan Multiple Range Test (DMRT) test at 5% level. The results showed that all treatments produced bioactive compounds and formed inhibit zone of each test bacteria. The best time to obtain an antibacterial antibacterial extract on corn hair is 50 minutes. This was supported by the lowest pH average of 5.1 and the highest mean total phenol obtained from treatment A3 (50 minutes) was 7288,64 μgGAE / g and at 75% concentration formed the largest bacterial inhibition zone in each test bacteria.</p>
