Abstract

Research on physical interaction of chitosan-alginate entrapping extract of papaya leaf (Carica papaya L) into submicron particles formation has been performed. Preparation of papaya leaf extract into submicron particle dosage form of chitosan and sodium alginate polymer using ionic gelation method aimed to increase the solubility of extract. Submicron particles consisting of papaya leaf extract, chitosan, sodium alginate and CaCl2 were combined using variation of stirrer speed of 500, 750, and 1000 RPM. The optimum formula obtained has a speed of 1000 RPM with the percent EE value of 71.90%. The results of submicron particles characterization such as diameter and particle size distribution (PDI) using particle size analyzer (PSA) tools were 189.2 nm and 0.330. The results of XRD revealed the changes of type of crystalinity form to amorphous on submicron particles. The results of FTIR revealed the physical interaction without shifting of wave number of carbonyl, amine, and hydroxyl group which indicated that there were no chemical interactions occurred. These data indicated that papaya extract can be formulated into submicron particles of chitosan-alginate polymer.

Abstract

A study regarding ionic-gelation submicron particle of papaya leaves (Carica papaya L.) extract with lactic acid of weeds potentially for antidiarrhea has been conducted. Preparation of papaya leaves ethanolic extract and lactic acid isolate into particles was done by ionic gelation method. This study aimed to determine: the major compound of extract, the total quercertine of extract, the percent value of encapsulation efficiency of the optimum formula which was varied by (CaOH)2 of the three formulas, and physical properties of particles. Formula 1 was using (CaOH)2 of 12.5 gram; formula 2 (CaOH)2 of 17,5 gram; formula 3 (CaOH)2 of 22.5 gram. The results showed formula 1 as the optimum formula that has the highest %EE. The average %EE values ??of F1; F2; F3 respectively were 80,82%; 80,41%; 80,31%. The results of particle characterization using the PSA in the optimum formula produced particle size values ??with an average of 253.6 nm, PDI of 0.218, and zeta potential +8 mV respectively.

Abstract

Bractea merupakan daun pelindung pada bunga, bractea bunga rambusa berwarna hijau, berbulu halus dan memiliki aroma khas. Bractea bunga rambusa memiliki kandungan metabolit sekunder yaitu alkaloid, fenolik dan flavonoid. Tujuan penelitian ini untuk mengetahui aktivitas antioksidan dan kandungan total flavonoid ekstrak dan fraksi bractea bunga rambusa. Ekstrak etanol bractea bunga rambusa diperoleh dengan metode maserasi, dilanjutkan dengan fraksinasi menggunakan pelarut n-heksan, etilasetat dan air. Penentuan aktivitas antioksidan dengan DPPH dan kandungan total flavonoid menggunakan spektrofotometri UV-Vis dengan pembanding asam galat dan kuersetin. Hasil penelitian memperlihatkan, aktivitas antioksidan ekstrak etanol IC50 71,22 μg/mL, fraksi n-heksan IC50 72,31 μg/mL, fraksi etil asetat IC50 77,31 μg/mL, dan fraksi air IC50 884,94 μg/mL.  Kandungan total flavonoid ekstrak etanol 32,264 mg QE/g, fraksi n-heksan 22,07 mg QE/g, fraksi etil asetat 46,87 mg QE/g dan fraksi air 44,32 mg QE/g. Aktivitas antioksidan yang dimiliki oleh ekstrak etanol, fraksi n-heksan, fraksi etil asetat dalam kategori kuat, dan fraksi air kategori lemah. Kandungan total flavonoid paling tinggi berturut-turut terdapat pada fraksi etil asetat, fraksi air, ekstrak etanol dan fraksi n-heksan.
