Abstract

Angkak dan bekatul merupakan pangan fungsional yang berpotensi sebagai agen terapi untuk mengendalikan gula darah, dikarenakan kandungan antioksidan alaminya. Tujuan penelitian adalah untuk mengevaluasi pengaruh campuran ekstrak angkak dan bekatul dalam menghambat peroksidasi lipid serta efeknya terhadap organ pankreas, hati dan ginjal tikus hiperglikemik secara histopatologi. Tikus dibagi ke dalam 7 kelompok yaitu kelompok kontrol normal, kontrol negatif, kontrol positif, formulasi ekstrak angkak bekatul kelompok I, II, III dan IV (20:1400, 40:700, 30:1050, dan 60:2100 mg/kg BB). Parameter pengujian yang dilakukan adalah konsentrasi malondialdehid (MDA) dan aktivitas enzim aminotransferase (ALT/AST) serum darah tikus dan histopatologi organ pankreas, hati dan ginjal. Campuran terbaik dalam menghambat pembentukan MDA dan peningkatan enzim ALT/AST adalah kelompok III dengan konsentrasi MDA (3,.31±0,.53 nmol/ml) dan aktivitas enzim ALT (35,.80±5,.63 U/l) tidak berbeda nyata dengan kontrol normal (4,.85±2,.32 nmol/ml) dan (27,.85±8,.13), sementara aktivitas enzim AST (67,.221±16,.05) mengalami penurunan namun berbeda nyata dengan kontrol normal (4,.365±0,.00). Kondisi histopatologi organ pankreas, hati, dan ginjal tikus semua kelompok perlakuan menunjukkan kemampuan dalam memperbaiki kerusakan organ. Kesimpulannya, campuran angkak dan bekatul 30:1050 mg/kg BB memiliki kemampuan terbaik dalam meghambat peroksidan lipid.Angkak and Rice Bran Extract to Prevent Lipid Peroxidation in Spague-Dawley Rats HyperglycemicAbstractAngkak and rice bran is a functional food that has potential as a therapeutic agent to control blood sugar. This potential is due to the content of natural antioxidants in red yeast rice and rice bran. The objective of this research was to evaluate the effect of angkak and rice bran extract as lipid peroxidation inhibition. The effect on the pancreatic, liver and kidney organs in hyperglycemic rats by histopatological study was also analyzed. Rats were divided into 7 groups namely normal control group, negative control, positive control, rice bran extract formulation on gorup I, II, III, IV (20: 1400, 40: 700, 30: 1050, and 60: 2100 mg/kg BW). The analysis parameters carried out were the concentration of malondialdehyde (MDA), the activity of the serum alanine/aspartat aminotransferase (ALT/AST) enzymes and rat histopathology of pancreatic, liver and kidney organs. The best mixture of angkak and rice bran to inhibit the formation of MDA and increase the ALT/AST enzyme was group III with MDA concentration (3,.31±0.,53 nmol/ml) and ALT enzyme activity (35.,80±5,.63 U/l) was not significantly different from normal control (4,.85±2,.32 nmol/ml) and (27.,85±8,.13), while the enzyme activity of AST (67,221±16,.05) decreased but was significantly different from normal controls (4,365±0,.00). Histopathological conditions of pancreatic, liver, and kidney organs of rats in all treatment groups showed the ability to repair damaged organs. In conclusion, the mixture of red yeast rice and rice bran 30:1050 mg/kg BW had the best ability to inhibit lipid antioxidants.

Abstract

Belimbing wuluh merupakan tanaman jenis buah dan obat tradisional. Tanaman belimbing wuluh sudah sering dimanfaatkan masyarakat salah satunya untuk mengobati penyakit seperti batuk dan radang rektum. Tujuan penelitian ini adalah menguji senyawa fitokimia, menganalisis kandungan total fenolik dan flavonoid, serta aktivitas antioksidan dan antiinflamasi secara in vitro pada ekstrak etanol daun belimbing wuluh. Metode yang dilakukan pada penelitian ini adalah ekstraksi daun belimbing wuluh, skrining fitokimia, perhitungan total fenol dan flavonoid, uji aktivitas antioksidan, dan uji aktivitas antiinflamasi. Senyawa fitokimia yang terkandung pada ekstrak etanol daun belimbing wuluh adalah saponin, tanin, steroid, flavonoid, dan alkaloid. Kandungan total fenolik dan flavonoid ekstrak etanol daun belimbing wuluh secara berturut-turut sebesar 39,03 dan 97,28 µg QE/mg. Ekstrak etanol daun belimbing wuluh memiliki aktivitas antioksidan yang tergolong sangat kuat, sementara aktivitas antiinflamasinya terutama ditunjukkan pada konsentrasi ekstrak 200 µg/ ml, memiliki nilai persen inhibisi hemolisis yang paling tinggi. Kesimpulannya, ekstrak etanol daun belimbing wuluh dapat menjadi salah satu sumber antioksidan dan antiinflamasi alami.Ethanol Extracts of Averrhoa Bilimbi Leaf Demonstrated Antioxidative and Anti-inflammatory ActivityAbstractAverrhoa bilimbi, a fruit-bearing plant, has been traditionally used for medicinal purposes such as treatment of cough and rectal inflammation. In this current work, ethanol extract of Averrhoa bilimbi leaf was analyzed, with regard to phytochemical composition, i.e. total phenolic, and flavonoid, antioxidant activity, and in vitro antiinflammation activity. Extraction of carambola leaves, phytochemical screening, total phenolic and flavonoid contens, assay of antioxidant activity, and assay of anti-inflammatory activity were done in this research. As a result, the leaf extract positively contained some phytochemical compounds, i.e. saponin, tannin, steroid, flavonoid, and alkaloid. Furthermore, total phenolic and flavonoid of the leaf extract was found at 39.03 and 97.28 µg QE/mg extract, respectively. Additionally, antioxidant activity of the leaf extract was classified as very strong, while its anti-inflammatory feature at extract concentration of 200 µg/ml exhibited the highest inhibition of hemolysis. In summary, the ability of Averrhoa bilimbi leaf ethanol extracts to act as antioxidative and anti-inflammatory agents was determined and this may open the use for natural antioxidant and anti-inflammatory agents.
