Abstract

ABSTRACT   Effervescent  drink from pomelo fruit contains flavonoid compound namely naringin that has been reported has an antidiabetic activity. This research was conducted to determine the effect of treatment with pomelo fruit effervescent which made from pomelo juice powder and extract of pomelo peel powder in reducing blood glucose levels of streptozotocin induced mice. This research was consisted of three steps i.e: making of effervescent powder, preparation of experimental animals, and in vivo test in experimental mice.  In in vivo test, each group consisted of six mices that were given 6 treatments i.e: normal mice with aquadest (negative control), DM mice with aquadest (positive control), DM mice treated with pomelo effervescent dose of 13 mg/20 g bw mice, 26 mg/20 g bw mice, 39 mg/20 g bw mice, and DM mice treated with glibenclamid dose of  0,65 mg/kg bw mice for 14 days. Parameters which were used in this study including mice body weight and mice glucose blood  level. The result showed that DM mice group that treated with pomelo effervescent dose 26 mg/20 g bw mice showed the most excellent treatment in reducing blood glucose level and maintaining body weight within 14 days treatment although its ability is still below the diabetic mice group that treated with glibenclamid dose of  0,65 mg/kg bw mice. Keywords: Diabetes, Effervescent, Hyperglycemia, Naringin, and Pomelo ABSTRAK   Minuman effervescent jeruk bali diketahui mengandung senyawa biokimia flavonoid naringin yang dikenal memiliki aktivitas antidiabetes. Penelitian ini dilakukan untuk mengetahui pengaruh pemberian effervescent jeruk bali yang dibuat dari serbuk sari jeruk bali dan serbuk ekstrak kulit jeruk bali terhadap penurunan kadar glukosa darah mencit yang diinduksi streptozotosin. Penelitian ini terdiri dari tiga tahap yaitu pembuatan minuman effervescent, persiapan hewan percobaan, dan pengujian in vivo pada mencit percobaan. Dalam uji in vivo, kelompok mencit masing-masing terdiri dari 6 ekor dan diberikan 6 perlakuan yaitu mencit normal dengan pemberian akuades (kontrol negatif), mencit DM dengan pemberian akuades (kontrol positif), pemberian minuman effervescent jeruk bali dengan dosis 13 mg/20 g bb mencit, 26 mg/20 g bb mencit, 39 mg/20 g bb mencit, pemberian sediaan pembanding (glibenklamid) dosis 0,65 mg/kg bb mencit selama 14 hari. Parameter yang digunakan dalam penelitian ini adalah perubahan berat badan dan kadar glukosa darah puasa mencit. Hasil penelitian menunjukkan bahwa kelompok mencit dengan perlakuan pemberian effervescent jeruk bali dosis 26 mg/20 g bb mencit memiliki kemampuan paling baik dalam mempertahankan berat badan dan menurunkan kadar glukosa darah mencit selama 14 hari pemberian perlakuan walaupun masih dibawah kelompok mencit DM dengan pemberian sedian pembanding (glibenklamid) 0,65 mg/kg bb mencit.   Kata kunci: Diabetes, Effervescent, Hiperglikemik, Jeruk bali, dan Naringin

Abstract

ABSTRACT   Functional drinks of boiled leaf water by adding cinnamon extract that has been reported has activity to reduce cholesterol levels. This research was conducted to determine the effect of the addition of cinnamon extracts in functional drinks decoction of bay leaf on the quality and consumer acceptance and also in  decreasing of blood cholesterol levels of rats. This research was consisted of 2 (two) steps i.e: making functional drinks of boiled leaf water by adding cinnamon extract and testing the effect of hypocholesterol with boiled bay leaf stew containing cinnamon extract in-vivo in experimental rats. The group of mice were given 5 treatments, namely the administration of aquadest, the provision of bay leaf decoction drink with the addition of cinnamon extract of 100, 200, and 300 mg, and the provision of a comparative preparation of gemfibrozil dose of 21.6 mg/200 g b/day. The result showed that rat group that treated with cinnamon extracts dose 300 mg showed the most excellent treatment in decreasing of total cholesterol and LDL cholesterol in blood rats and being able to increase HDL cholesterol in rat blood within 14 days treatment although its ability is still below the rat group that treated with gemfibrozil dose of  21,6 mg/kg bw rat.

ABSTRAK   Minuman rebusan daun salam yang mengandung ekstrak kayu manis diketahui mengandung senyawa biokimia flavonoid dan asam sinamat yang dikenal memiliki aktivitas menurunkan kadar kolesterol. Penelitian ini dilakukan untuk mengetahui pengaruh penambahan ekstrak kayu pada minuman fungsional rebusan daun salam terhadap penurunan kadar kolesterol darah tikus. Penelitian ini terdiri dari 2 (dua) tahap yaitu pembuatan minuman fungsional air rebusan daun salam dengan penambahan ekstrak kayu manis dan pengujian efek hipokolesterol dengan minuman rebusan daun salam yang mengandung ekstrak kayu manis secara in-vivo pada tikus percobaan.  Kelompok tikus diberikan 5 perlakuan yaitu pemberian akuades, pemberian minuman rebusan daun salam dengan penambahan ekstrak kayu manis 100, 200, 300 mg, dan pemberian sediaan pembanding gemfibrozil dosis 21,6 mg/200 g bb/hari. Hasil penelitian menunjukkan bahwa kelompok tikus dengan pemberian dosis 300 mg ekstrak kayu manis memiliki kemampuan paling baik dalam menurunkan kadar kolesterol total dan kolesterol LDL darah tikus dan mampu meningkatkan kadar kolesterol HDL darah tikus selama 7 hari walaupun masih di bawah kelompok tikus  dengan pemberian gemfibrozil 21,6 mg/ 200 g bb tikus.   Kata kunci: Hiperkolesterolemia, Kayu Manis, Asam Sinamat, Flavonoid, Rebusan Daun Salam.
