Abstract

Tanaman Jati (Tectona grandis linn. F) umumnya hanya dimanfaatkan bagian kayunya untuk industri meubel, namun bagian lain seperti daun kurang dimanfaatkan. Daun jati terutama bagian pucuk daun muda dapat menghasilkan pigmen. Produksi serbuk nano pigmen dari daun jati dan karakterisasi serbuk nano pigmen tersebut belum dilakukan. Tujuan penelitian ini adalah menghasilkan nano pigmen dari pucuk daun jati muda dalam bentuk serbuk dengan menggunakan persentase filler yang berbeda dan melakukan karakterisasi serbuk nano pigmen jati tersebut. Pucuk daun jati muda diberi perlakuan mekanik dengan penggerusan kemudian disaring, larutan yang diperoleh diukur partikelnya dengan Particle Size Analyzer (PSA), dan dikeringkan dengan penambahan filler maltodekstrin 5% dan 10%. Serbuk yang diperoleh dihitung rendemen, ukuran partikel, dan kelarutan dalam air. Warna merah yang dihasilkan dari filtrat pucuk daun jati muda berasal dari zat warna antosianin yang terkandung dalam daun jati muda. Ekstrak dari pucuk daun jati muda memiliki ukuran dengan kisaran 87,8- 318,1 nm dengan ukuran rata-rata 109,2 nm. Hal ini menunjukkan bahwa ekstrak tersebut merupakan produk nano di alam. Penambahan filler dengan konsentrasi berbeda berpengaruh terhadap warna, rendemen, ukuran partikel serbuk, dan kelarutan pigmen serbuk dalam air.

Abstract

Uncaria gambir Roxb. is an industrial crop commodity that has a high economic value and good prospect for farmers and exporter. Gambier of traditional processed products (raw gambier) generally have various catechin content, so it is required further handling to increase the purity of catechins from raw gambier. The research was aimed to get a process technology on the making of pure gambier and standardized catechins. Sources of raw materials was obtained from extraction process through steaming leaves and twigs of gambier (KA) using equipment from aluminum (RA) and from iron (RF). Purification of raw gambier through repeated extraction with water could decrease tannin content from 24% to 2.4% and increase catechin levels between 40% to 74%. Gambier with a low tannin content (catechin KA) through re-extraction using water had the highest increase of catechin content with a color of yellowish white product. The iron-containing equipment affected the color of the pure gambier produced, which was reddish-brown. The effect of solvent on further extraction using ethyl acetate solvent resulted in higher catechin content (up to 99%) compare to ethanol (95%). The catechin purity of KA samples was tested by looking at its stability at varying levels of acidity, showing catechins of gambier was stabile at pH 6.ABSTRAK Uncaria gambir Roxb. merupakan komoditas tanaman industri yang memiliki nilai ekonomi tinggi serta mempunyai prospek cukup baik bagi petani dan pemasok negara-negara asing. Gambir hasil olahan tradisional (gambir asalan), umumnya memiliki kandungan katekin yang beragam, sehingga diperlukan penanganan lebih lanjut untuk meningkatkan kemurnian katekin dari gambir asalan. Tujuan penelitian adalah untuk mendapatkan teknologi proses pembuatan gambir murni dan katekin terstandar. Sumber bahan baku diperoleh dari proses ekstraksi melalui pengukusan daun dan ranting tanaman gambir (KA) menggunakan peralatan dari aluminium (RA) dan dari besi (RF). Pemurnian gambir asalan melalui ekstraksi berulang dengan air dapat menurunkan kadar tanin, yaitu dari 24% sampai 2,4% dan meningkatkan kadar katekin, yaitu antara 40% sampai 74%. Gambir dengan kandungan tanin rendah (katekin KA) melalui ekstraksi ulang menggunakan air memiliki peningkatan kadar katekin tertinggi dengan warna produk putih kekuningan. Peralatan mengandung besi berpengaruh terhadap warna dari gambir murni yang dihasilkan, yaitu berwarna coklat kemerahan. Pengaruh pelarut terhadap ekstraksi lanjut menggunakan pelarut etil asetat menghasilkan kadar katekin lebih tinggi (sampai 98%) dibandingkan etanol (95%). Kemurnian katekin sampel KA diuji dengan melihat stabilitasnya pada berbagai tingkat keasaman, menunjukkan katekin dari gambir stabil pada pH 6.

Abstract

The aim of this study is to convert Nigella sativa black seed extract from liquid phase into solid phase by microencapsulation using spray drying method. The benefits hoped from this research are obtaining the dry extract to be formulated into pharmaceutical variable dosage forms in order to increase the usefulness and variability products of Nigella sativa black seed extract. The spray drying method was done by adding Nigella sativa black extract into the gum arabic and maltodextrin solution. The evaluation of microencapsulated extract is including drug content, encapsulation efficiency, flow properties, compressibility, angle of repose, moisture content, particel size distribu-tion and microstructure of microcapsules. The result showed that microencapsula-tion of Nigella sativa black seed extract can be produced by spray drying method. The highest microencapsulation efficiency is at the coating solution concentration of 20% (gum arabic : maltodextrin = 50 : 50) and Nigella sativa black extract percentage of 30%.

Abstract

This study aimed to identify the effect of mechanical milling on the total phenolic content and antioxidant activity of mangosteen pericarp. Mangosteen pericarp was milled under different milling times (30, 90, 150, and 210 min). The particle morphology before and after milling was observed by scanning electron microscopy (SEM), and the average particle size was obtained from SEM images and analyzed statistically. The antioxidant activity was measured through the 2,2-diphenyl-1-picrylhydrazyl method. The total phenolic content for the non-milling sample was 14.52 × 104 µg GAE/g sample, and the highest total phenol content was 17.44 × 104 µg GAE/g sample for the sample milled for 210 min. The IC50 value decreased for samples with milling 150 and 210 min, which showed strong antioxidant activity, whereas the value of gallic acid equivalent increased. SEM observations showed the presence of agglomeration in the morphology of mangosteen pericarp samples. The average particle size of the mangosteen pericarp decreased as the milling time increased (up to 4499 nm for samples milled for 210 min). Therefore, mechanical milling had a significant effect on the phenolic content and antioxidant activity, which indicated an increase in the bioavailability of mangosteen pericarp.
