Result of analysis in phenolic dan flavonoid total content indicate that dry sago baruk higher compared fresh sago flour of baruk wet while tannin condensed content do not show difference. Result of examination of antioxidant activity indicated that fresh sago baruk having higher DPPH free radical scavenging activity compared to dry sago baruk (the average values of 83,08% and 81,49%, respectively). In contrast, total antioxidant and reducing power of dry sago baruk presented higher antioxidant activity compared to fresh sago baruk with average value (the average values of 109,48 and 92,52 μmole/100 g, respectively). Futhermore, correlations analysis revealed that total phenolic, flavonoid, tannin content with DPPH and FRAP scavenging activities were well positively correlated with each other (R= 0.7526; 0,7467 and 0,8146, respectively). Result of this research concluded that dry and fresh sago baruk trunks pith having phenolic compound and antioxidant activitiesSagu baruk (Arenga microcarpha) merupakan salah satu jenis tanaman endemik Kepulauan Sangihe Talaud, Sulawesi Utara yang potensial sebagai sumber pangan alternatif. Tujuan penelitian ini adalah untuk menentukan komposisi senyawa fenolik dan aktivitas antioksidan dari sagu baruk segar dan kering yang diekstraksi secara sekuensial dengan akuades dan filtrat. Empelur batang sagu segar dan kering diekstraksi secara sekuensial dengan akuades dan filtrat. Ekstrak tepung sagu baruk dianalisis kandung total fenolik, flavonoid dan tannin terkondensasi dengan spektrofotometer. Aktivitas antioksidan dievaluasi dengan penangkalan radikal bebas difenil pikrilhidrazil (DPPH), total antioksidan dan kemampuan mereduksi. Hasil analisis terhadap kandungan total fenolik dan flavonoid menunjukkan bahwa sagu baruk kering lebih tinggi dibandingkan dengan tepung sagu baruk basah sedangkan kandungan tannin terkondensasi tidak menunjukkan perbedaan. Hasil pengujian aktivitas antioksidan menunjukkan bahwa sagu baruk segar memiliki aktivitas penangkal radikal bebas DPPH lebih tinggi dibandingkan dengan sagu baruk kering (dengan persentase rata-rata berturut-turut adalah 83,08 dan 81,49%). Sebaliknya, total antioksidan dan kemampuan mereduksi sagu baruk kering memberikan aktivitas antioksidan tertinggi dibandingkan dengan sagu baruk segar (dengan rata-rata 109,48 dan 92,52 μmol/100 g).

Abstract

The objectives of the present research were evaluated effect of solvent extraction on antiphotooxidative from cloveleave (Eugenia aromatic (L). A certain quantity of powdered sample was extracted with methanol 80%, ethanol 80%and aseton 80%. After evaporation the extracts were dissolved in methanol and assayed for phenolic, flavonoid andcondensed tannin content. Singlet oxygen quenching and free radical activity of each extracts of spices at 500 ppmlevel were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical. Anti-photooxidative activity test wasconducted using linoleic acid as substrates each containing 5 ppm erythrosine as a photosensitizer. The resultshowed that solvent was significantly having effect on total phenolic, flavonoid and condensed tannin content.Methanol extract possessed highest total flavonoid and condensed tannin content than aseton and etanol. Methanolextract of clove leave was found to have the highest anti-photooxidative effect, followed by aseton and ethanol. Inaddition, ekstrak methanol showed any difference in it free radical scavenger effect than that of ethanol and asetonextracts. This results show that clove methanol extract has the best activity on photooxidation of linoleic acid andscavenger of free radical DPPH. These results suggest that the methanolic extract of clove leave contains somecompounds having singlet oxygen quenching and free radical scavenging activities on linoleic acid and free radicalDPPH.Penelitian ini bertujuan untuk mempelajari pengaruh pelarut ekstraksi terhadap aktivitas antifotooksidan dankomposisi fenolik yang terdapat pada ekstrak daun cengkeh.

Tujuan penelitian adalah untuk menentukan aktivitas antioksidan dan fotoprotektif tepung komposit dari pisang goroho, jagung manado kuning dan sagu baruk menggunakan perbedaan pelarut. Tepung komposit diproduksi menggunakan campuran tepung pisang, jagung dan sagu pada perbandingan 60:30:10. Tepung komposit dievaluasi menggunakan kandungan total flavonoid (metode aluminium), aktivitas antioksidan (uji radikal 1,1-diphenyl-2-phycrylhidrazyl) dan aktivitas fotoprotektif (uji SPF menggunakan spektrofotometer). Hasil penelitian ini menunjukkan bahwa kandungan total flavonoid tertinggi ditemukan pada pelarut aseton dibandingkan dengan methanol, ethanol, petroleum eter dan TPTJ (kontrol) pada tepung komposit. Aktivitas penangkal radikal bebas ekstrak aseton tepung komposit menunjukkan aktivitas paling tinggi daripada ekstrak etanol, metanol, petroleum eter dan TPTJ (kontrol). Hasil penelitian ini juga menunjukkan bahwa ekstrak aseton mempunyai aktivitas fotoprotektif paling tinggi daripada ekstrak metanol, etanol, petroleum eter dan TPTJ (kontrol) pada nilai SPF (sun protection factor). Secara keseluruhan, penelitian ini menyarankan bahwa ekstrak aseton tepung komposit mengandung komponen yang memberikan aktivitas antioksidan dan fotoprotekstif serta berpotensi melindungi kulit dari efek radiasi UV-B. Kata kunci: tepung komposit, pelarut, antioksidan dan fotoprotektif ABSTRACT  Banana, corn and sago are source of macronutriens, vitamines, minerals, dietary fiber and phytochemicals. The objective of this study was to determine antioxidant and photoprotective activities of composite flour from goroho banana, yellow Manado corn and baruk sago using different solvent. Composite flour was produced using mixture of banana, corn and sago flour in the ratio of 60:30:10. The composite flour extracted with petroleum ether, acetone, ethanol, and methanol by using a maceration extraction for 24 hours. The composite flour was evaluated using total flavonoid content (aluminium ion method), and free radical scavenging activity (1.1-diphenyl-2-phycrylhidrazyl radical assay). The in vitro photoprotective activity was studied by UV spectrophotometric method in the range of 290-320 nm. This result showed that the highest total flavonoid content was found in acetone solvent compared that of methanol, ethanol, petroleum ether, and TPTJ (control) in composite flour. The radical scavenging activity of acetone extract of flour composite showed the highest activity than ethanol, methanol, petroleum ether, and TPTJ (control). The results also showed that the acetone extract has highest photoprotective activity than methanol, ethanol and petroleum ether in sun protection factor (SPF) value. In overall, the present study suggests that acetone extract of composite flour contains components that give antioxidant and photoprotective activities and potency to protect skin of UV-B radiation effects. Keyword: composite flour, solvents, antioxidant, photoprotective
