Abstract

ABSTRAK Penelitian ini bertujuan untuk mempelajari aktivitas antioksidan fraksi pelarut Sagu baruk. Penelitian dimulai dengan mengekstraksi serbuk Sagu baruk menggunakan cara maserasi selama 4 hari dengan pelarut etanol 80%. Ekstrak kemudian dipartisi berturut-turut menggunakan pelarut n-heksan, etil asetat, butanol, dan aquades. Kemudian ditentukan kandungan total fenolik, total aktivitas. Hasilnya menunjukkan bahwa fraksi etil asetat memiliki kandungan total fenolik tertinggi diikuti fraksi butanol, n-heksan dan aquades. Kandungan total fenolik berturut-turut adalah 81,22; 41,43; 20,20; dan 14,39 mg/kg. Fraksi etil asetat juga memiliki total aktivitas antioksidan tertinggi dibandingkan dengan fraksi lain. Berdasarkan penelitian ini, dapat disimpulkan bahwa fraksi etil asetat adalah fraksi terbaik yang dapat berperan sebagai antioksidan.ABSTRACT To evaluate the antioxidant from the solvent fraction of Sago Baruk (Arenga microcarpha) was the purpose of this study. These study initiated by extracting the powder of Sago Banrk by way of maceration for 4 days using 80% ethanol. Extract then partitioned using a series of solvent such as n-hexane ethyl acetate, buthanol, and distilled water, respectively. Then continued to determined the total phenolic content, total antioxidant. The results showed that the ethyl acetate fraction had the highest content of total phenolic followed by the fraction of buthanol, n-hexane and distilled water, with the value of total phenolic content as follow 81.22 (ethyl acetate);41.43 (buthanol);20.20 (n-hexane); and 14.39 mg I kg (aquades). Ethyl acetate fraction also have the highest total antioxidant activity compared to the other fractions. Based on this study, the ethyl acetate fraction was the best fraction with the ability of antioxidant.

Abstract

This research aims to study the anti UV-B activity from solvent fractions of corncobs. The study initiating by extracting the powder corn cobs using way reflux for two hours with 80% ethanol. Extract then partitioned using a series of solvent; n-hexane, ethyl acetate, butanol and distilled water. Then was determined the effect of fractions against lipid oxidation induced by UV-B light. The results showed that the ethyl acetate fraction showed the lowest content of conjugated diene followed fraction of butanol, n-hexane and distilled water. The content of conjugated diene was 21.89; 25.11; 42.94; and 46.08 mmol/kg, respectively. Based on this study, the fraction of ethyl acetate fraction could act as an antioxidant and anti UV-B better than the other fractionsPenelitian ini bertujuan untuk mempelajari aktivitas anti UV-B dari fraksi pelarut tongkol jagung. Penelitian dimulai dengan mengekstraksi serbuk tongkol jagung menggunakan cara refluks selama dua jam dengan pelarut etanol 80%. Ekstrak kemudian dipartisi berturut-turut menggunakan pelarut n-heksan, etil asetat, butanol, dan aquades. Kemudian ditentukan pengaruh fraksi terhadap oksidasi lipid yang diinduksi dengan cahaya UV-B. Hasilnya menunjukkan bahwa fraksi etil asetat memiliki kandungan diena terkonjugasi terendahdiikuti fraksi butanol, n-heksan dan aquades. Kandungan diena terkonjugasi berturut-turut adalah 21,89; 25,11; 42,94; dan 46,08 mmol/kg. Berdasarkan penelitian ini, dapat disimpulkan bahwa fraksi etil asetat dapat berperan sebagai antioksidan dan anti UV-B lebih baik dibandingkan dengan fraksi lainnya.

Abstract

This study was intended to determine the sunscreen activity from the phenolic fraction of betel fruits. Betel fruits powder extracted with maseration method with ethanol 80%. Furthermore betel fruits extract liquid successively fractioned using petroleum eter, etyl acetate, butanol, ethanol and aquades. The phytochemical analysis of faction determined using total phenolic, flavonoid and condensed tannin content. The sunscreens activity was evaluated in sun protection factor (SPF) of fraction with spectrophotometry UV-vis.The best fractions were characterized functional group using infra red spectrophometer. The result showed that the butanol fraction have the highest total phenolic and condensed tannin content and petroleum eter fraction possessed highest total flavonoid content. Butanol fraction has the highest antioxidant activity than the other fraction. Aquades fraction (16.14) showed highest sun protection factor (SPF) value followed by petroleum eter, ethyl acetate, butanol and ethanol. SPF velue were 8.07; 6.93; 6.70; 5.38 dan 5.29.Penelitian ini bertujuan untuk menentukan aktivitas antioksidan dan potensi tabir surya dari fraksi buah sirih hutan. Serbuk buah sirih hutan diekstraksi dengan metode maserasi menggunakan pelarut etanol 80%. Ekstrak buah sirih hutan difraksinasi berturut turut dengan petroleum eter, etil asetat, butanol, etanol dan akuades. Analisis kandungan fitokimia fraksi-fraksi ditentukan berdasarkan total fenolik, flavonoid dan tannin terkondensasi. Aktivitas tabir surya pada fraksi-fraksi dievaluasi dengan analisis sun protection factor (SPF) menggunakan spektrofotometer UV-vis. Fraksi terbaik dikarakterisasi gugus fungsinya menggunakan spektrofotometer infra merah (FTIR). Hasil penelitian menunjukkan bahwa fraksi butanol memiliki kandungan total fenolik dan tanin terkondensasi tertinggi sedangkan kandungan flavonoid tertinggi terdapat pada fraksi butanol, petroleum eter dan etil asetat. Fraksi akuades memiliki aktivitas tabir surya tertinggi dibandingkan dengan fraksin diikuti fraksi petroleum eter, etil asetat, butanol dan etanol. Nilai SPF berturut-turut adalah 8,07; 6,93; 6,70; 5,38 dan 5,29.
