Abstract

Dried yogurt is one of yogurt product development innovations. Beside increases the shelf life, dried yogurt is also ore practical because it reduces the volume to the easier distribution process. Dried yogurt enriched by Difructose Anhydride III as functional food in increasing calcium absorption is useful as osteoporosis prevention. The purpose of this study was to analyze the characteristics of dried yogurt enriched by DFA III from dahlia and chicory tubers as functional drink on physicochemical, microbiology, and organoleptic properties. The research stages include: (1) The production of dried yogurt without enrichment (Y), with DFA III enrichment from dahlia tubers (YD), and with DFA III commercial enrichment from chicory tubers (YC), (2) The test for physicochemical, microbiology, and organoleptic properties.The results showed that the purity level of DFA III from dahlia tubers was 96.0% and commercial DFA III from chicory tubers was 99.9%. The best results were obtained from the dried yogurt enriched by DFA III from dahlia which produced yield of 14.90±1.27%  and dried yogurt enriched by DFA III from chicory tubers (YC) which produced yield of 14.71±1.69% (p<0.05). YD product had  moisture content of 7.89±0.01%; ash content of 3.43±0.06%; protein content of 12.43±0.13%; fat content of 1.22±0.07%; carbohydrate content of 75.02±0.10%; pH/acidity of 3.9±0.00; acidity as lactic acid of 0.49±0.02%; whiteness degree of 89.29±0.08%; and lactic acid bacteria viability of 1.20x10 levels got like preference, while for  texture and taste level got  medium-like preference. Dried yogurt enriched by DFA III from dahlia tubers could improve the viability of lactic acid bacteria as probiotic. It means that the dried yogurt prevention.ABSTRAKYoghurt keringmerupakan salah satu inovasi pengembangan produk yoghurt. Yoghurt kering dapat meningkatkan daya simpan yoghurt serta lebih praktis karena mengurangi volume sehingga lebih memudahkan dalam proses distribusi. Pengayaan yoghurt kering dengan III sebagai pangan fungsional yang berperan dalam meningkatkan penyerapan kalsium bermanfaat sebagai pencegahan terhadap osteoporosis. Tujuan dari penelitian ini adalah untuk menganalisis karakteristik yoghurt kering yang diperkaya dengan DFA III dari umbi dahlia dan umbi meliputi: (1) proses pembuatan yoghurt kering tanpa pengayaan (Y), diperkaya dengan DFA III dari umbi dahlia (YD), dan diperkaya dengan DFA III komersial dari umbi organoleptik. Hasil penelitian menunjukkan bahwa tingkat kemurnian DFA III dari umbi dahlia 96,0% dan DFA III komersial dari umbi 99,9%. Hasil terbaik diperoleh dari yoghurt kering yang diperkaya dengan DFA III dari umbi dahlia (YD) menghasilkan rendemen 17,83±0,36% lebih tinggi secara nyata dibandingkan dengan tanpa pengayaan (Y) 14,90±1,27% dan pengayaan dengan DFA III dari umbi  (YC) 14,71±1,69% (p<0,05). Produk YD mengandung kadar air 7,89±0,01%; kadar abu 3,43±0,06%; kadar protein 12,43±0,13%; kadar lemak 1,22±0,07%; kadar karbohidrat 75,02±0,10%; pH/derajat keasaman 3,9±0,00; keasaman sebagai asam laktat 0,49±0,02%; derajat putih 89,29±0,08%; dan viabilitas bakteri asam laktat 1,20x107cfu.g-1. Pengujian organoleptik menggunakan 40 panelis semi terlatih, dengan hasil penilaian untuk aroma dan warna menunjukkan kriteria suka, untuk tekstur dan rasa menunjukkan kriteria agak suka. Yoghurt kering yang diperkaya dengan DFA III dari umbi dahlia yang bersifat prebiotik dapat meningkatkan viabilitas bakteri asam laktat sebagai probiotik yang menunjukkan bahwa produk tersebut dapat digolongkan sebagai produk sinbiotik dan dapat digunakan sebagai minuman fungsional untuk meningkatkan penyerapan kalsium sebagai pencegahan terhadap osteoporosis.

Abstract

Hedyotis corymbosa, with local name rumput mutiara, is an anti-inflammatory, anti-cancer and hepatoprotective traditional medicine.  The ethanol extract of H. corymbosa L. shows inhibitory activity to human YMB-1 breast cancer cell line with an IC50 of 6.51 mg/ml.  The methylene chloride fraction shows a potential cytotoxic activity with an IC50 of 2.75 mg/ml.  To obtain a lead compound, the extract was further purified by column chromatography. A pure compound is obtained which shows inhibitory activities against YMB-1, HL60 and KB human cell lines with IC50 values of 0.7; 11.0 and 104.2 mg/ml, respectively.  Based on the 1D and 2D FT-NMR data, the isolated compound is an asperuloside.

Abstract

P-glycoprotein (P-gp) resistance in cancer cells decreases intracellular accumulation of various anticancer drugs. This multidrug resistance (MDR) protein can be modulated by a number of non-cytotoxic drugs. We have screened 30 chincona alkaloids derivatives as a potent P-gp inhibitor agent in silico. Hereby, we report the highest potential inhibitions of P-gp is Cinchonidine isobutanoate through molecular docking approach. with affinity energy -8.6 kcal/mol and inhibition constant, Ki is 4.89 x 10-7 M. Cinchonidine isobutanoate is also known has molecular weight below 500, Log P value 3.5, which is indicated violation free of Lipinski`s rule of five. Thus, Cinchonidine isobutanoate is the most potent compound as anticancer compare to other Cinchona alkaloids. Ultimately, we design Cinchonidine isobutanoate for further lead synthesis by using DBSA, act as a combined Brønsted acid-surfactant-catalyst (BASC) to obtain high concentration of organic product by forming micellar aggregates which is very powerful catalytic application in water environment.

Abstract

Ethanol extract of Syzygium cumini (jamblang) leaves reveal its significant α-glucosidase inhibitory activity which perform the potential activity of this plant extract as antidiabetic agent. However, other bioactivities of this plant extract have been reported. The aim of current study was to evaluate the comparison of in vitro antidiabetic, antioxidant and cytotoxic activity of S. cumini fractions. The S. cumini leaves ethanol extract was fractionated by using column chromatography with n-hexane, ethyl acetate and methanol as eluents. Seven fractions were obtained from column chromatography (F1-7). The results showed that the best antidiabetic activity was found in F5 (93% α-glucosidase inhibitory activity), the best antioxidant activity was found in F4 (83% inhibition of DPPH free radical) and the best cytotoxic activity was found in F2 (69% growth inhibition of T47D breast cancer cell line). Therefore besides in vitro antidiabetic activity, fractions of S. cumini leaves ethanol extract also showed antioxidant and cytotoxic activities. Since the results showed that the most active fractions for antidiabetic, antioxidant and cytotoxicity were differed, it could be possible to isolate the different potential active compounds for each activity.Keywords : Syzygium cumini, α-glucosidase inhibitor, DPPH, cytotoxicity
