Abstract

Tanin secara umum digunakan sebagai astringent saluran pencernaan, antiseptic lemah (pada luka bakar), keracunan alkaloid, antivirus, antioksidan, dan menghambat pertumbuhan tumor. Beberapa tanaman yang mengandung tanin tersebut, diantaranya adalah tanaman kelapa (Cocos nucifera L.). dalam penelitian ini dilakukan analisis kualitatif dan kuantitatif pada serabut kelapa. Dari hasil kualitatifnya, serabut kelapa tua dan serabut kelapa muda termasuk jenis tanin terkondensasi. Sedangkan dari hasil penetapan kadar tanin total secara permanganometri menunjukkan kadar tanin pada serabut kelapa tua sebesar 4,28 % dan kadar tanin pada serabut kelapa muda sebesar 5,62 %.

Abstract

Telah dilakukan penelitian mengenai penentuan kadar tanin kulit buah pisang masak (Musa paradisiaca L.) varietas kepok secara spektrofotometri dan permanganometri. Serbuk kulit buah pisang diekstraksi dengan cara maserasi kinetik menggunakan pelarut etanol 70%. Ekstrak yang didapat diuji kualitatif maupun kuantitatif. Hasil uji kualitatif menunjukkan adanya tanin dan jenis taninnya adalah tanin terkondensasi. Uji kuantitatif secara spektrofotometer didapatkan panjang gelombang maksimum asam galat adalah 765,50, dan waktu yang diperlukan untuk mencapai serapan konstan adalah 90 menit. Kurva baku asam galat adalah : y = 0,0601 + 0,0887x, nilai r hitung = 0,999. Rata-rata kadar tanin yang didapat secara spektrofotometri adalah 2,45%. Dengan menggunakan permanganometri, didapatkan normalitas asam oksalat 0,11N dan normalitas KMnO4 0,1097N. Rata-rata kadar yang didapat dengan permanganometri 0,8%.

Abstract

Santalum album L (Cendana ) is a plant has many benefits that grow a lot in Indonesia. Already done research on the roots and stems of the cendana plant, but not research on the leaf. In this reseacrh, the volatile component from of the leaf of this plant was analyzed in qualitative and quantitative. For qualitative analysis are organoleptic observations, the determination of the refractive index, spesific gravity, profile Thin Layer Chromatography (TLC), profile gas chromatography and mass spectra (GC-MS). Quantitative analysis performed assay of essential oil with stahl distillation method. Santalum album’s essential oil has a clear liquid, the color is brown, has a very fragrant aroma and taste is a little bit bitter. The spesific gravity of the essential oil is 1,28±0,021, the refractive index is 1,46±0,01 and the total content is 0,6±5,03ൈ10-5(v/w). profileTLC revealed that there are 4 spot. The result GC-MS showed there were 6 components, and the highest component is Pyrrolidine 1-(ethyl-1-cyclohexen-1-yl).

Abstract

Abstract - This study aims to analyze qualitatively and quantitatively essential oils on green betel leaf (Piper betle L.) and red betel leaf (Piper crocatum Ruiz & Pav.) Taken from Kupang City, NTT. Qualitative test results of volatile oil of green betel leaf include liquid form, aromatic odor, brownish yellow color, bitter spicy taste, weight of type 0,7455 ± 0,013, and refractive index 1,46595 ± 0,019. Essential oils of red betel leaf include liquid form, aromatic odor, yellow color, bitter spicy taste, weight of type 0,7724 ± 0,001, and refractive index 1,46789 ± 0,009. Thin Layer Chromatography (TLC) stains on the volatile oil of green betel leaf showed 8 stains and the red betel leaves showed 9 stains. Analysis of Gas Chromatography-Mass Spectrometry (GC-MS) showed that on the volatile oil of green betel leaves there were 35 compounds with % quality> 90%, and dominated by 5 components of compounds with the largest area of Sabinene (6.72%), α -Copaene (6.23%), L-Calamenene (1.60%), trans-Caryophyllene (0.77%) and Cavicol (0.65%). Essential oil of red betel leaf 35 compound with% quality> 90%, and dominated by 5 component of compound with the largest area of β-Myrcene(13,80%), Linalool L (3,29%), α-Thujene (1 , 52%),γ- Terpinene (1.36%), cis-β-Terpineol (1.15%).
