Hiperurisemia adalah keadaan dimana terjadi peningkatan kadar asam urat dalam darah diatas normal. Tanaman kenikir (Cosmos caudatus) merupakan tanaman yang banyak dijumpai di lingkungan sekitar, serta tanaman yang sudah tidak asing lagi dan telah banyak dikonsumsi sebagai sayuran. Salah satu kandungan dalam kenikir adalah senyawa golongan flavonoid. Pada penelitian ini mikroemulsi ekstrak kenikir digunakan untuk menurunkan kadar asam urat pada tikus yang diinduksi hati ayam. Mikroemulsi dibuat dengan menggunakan virgin coconut oil (VCO) sebagai fase minyak, Tween 80 dan Span 80 sebagai surfaktan dan gliserin sebagai kosurfaktan. Penelitian menggunakan 15 ekor tikus putih jantan galur wistar yang diinduksi jus hati ayam. Tikus dibagi menjadi 3 kelompok, yaitu kelompok kontrol negatif mikroemulsi placebo, kontrol positif mikroemulsi Allopurinol 3,6 mg/200 g BB tikus, serta kelompok perlakuan mikroemulsi daun kenikir  10 mg/200 g BB tikus yang diberikan secara peroral. Pengukuran kadar asam urat dilakukan pada hari ke-0 (kadar awal), hari ke-7 (kadar setelah induksi) dan hari ke-13(kadar setelah perlakuan). Persen penurunan kadar asam urat dalam darah dianalisis secara statistika dengan taraf kepercayaan 95%. Hasil uji statistika menyatakan ada perbedaan antara kelompok kontrol negatif dan positif dengan kelompok perlakuan mikroemulsi daun kenikir memiliki nilai signifikansi 0,000.

<p>Virgin coconut oil (VCO) is high quality coconut oil and categorized as the healthiest oil and functional foods. Based on these benefits, the development of a VCO in emulsion product might increase the human consumption of coconut oil because consumers dislike the only taste of pure VCO. The aim of this study was to develop the water compatible form of VCO through nano-emulsification. The effect of different types and amounts of surfactants (Tween 80 and Span 80) on the physio-chemical characteristic of emulsion containing VCO was investigated. VCO based emulsions were prepared with the aid of Ultra-Turrax homogenizer. Emulsions were developed by adding and mixing VCO with surfactants. The ratio of Tween 80 and Span 80 used were 0:10, 2.5:7.5, 5:5, 7.5:2.5, and 10:0. The droplet size of nanoemulsions consisting of Tween 80:Span 80 (0:10, 2.5:7.5, 5:5, 7.5:2.5, and 10:0) were 1.343, 0.606, 0.829, 1.439, and 2.506µm, respectively. Based on the TEM analysis and polydispersity index (PDI) &gt;0.5 showed the oil droplets are in not uniform shape, indicating a unstable emulsion. VCO emulsion with ratio Tween 80:Span 80 (0:10) obtained a homogeneous emulsion (stable) compare than that of others and w/o type emulsion. The stability of emulsion is evaluated by turbidity measurement using UV-VIS spectrophotometer with wavelength 502 nm. A combination of  treatments (ambient condition, thermal treatmeant (40°C)), and centrifuge) of VCO emulsion has resulted on thermal treat, the turbidity measured from the emulsion was higher than the other emulsion, reflecting the presence of the smaller droplets in this emulsion.</p>

β-Carotene exhibits a wide range of health benefits, but its application in food formulation is very limited because of its instability and susceptibility to degradation. The stability of β-carotene can be improved by incorporation into an oil-in-water (o/w) emulsions. The objective of this research was to characterize β-carotene loaded nanoemulsions prepared with spontaneous emulsification method using ternary food-grade surfactants (Tween 80, Span 40, Span 80) and palm oil or VCO (virgin coconut oil) as oil phase with the surfactant-oil ratio of 4. The physicochemical stability of β-carotene loaded nanoemulsions during simulated digestions, which consist of the mouth, stomach, and intestine phases, was also evaluated using in-vitro digestion model. The results showed that β-carotene loaded nanoemulsions, prepared either using VCO or palm oil as the oil phase, had neutral pH (6.8±0.1), mean particle diameter of 129 -159 nm, showed monomodal particle size distribution with low polydispersity index (PdI) values  (0.214 - 0.266), and were not significantly different in zeta potential values ([-6,59]–[-8,9]). The β-carotene loaded nanoemulsions with VCO as the oil phase had a smaller mean particle diameter than that of palm oil. The physical stability of the β-carotene loaded nanoemulsions against digestive simulation in the mouth, stomach or intestine phases was not influenced by the oil phase type.  Both nanoemulsions were stable against simulated digestion in the mouth and stomach phases. After passing through the intestinal phase, the mean particle diameter increased and the particle size distribution changed from monomodal to bimodal. The β-carotene retention after passing through the mouth, stomach and intestinal phases of the β-carotene loaded nanoemulsion prepared using VCO were not significantly different from the palm oil. ABSTRAKβ-Karoten mempunyai berbagai manfaat kesehatan, namun aplikasinya dalam formulasi pangan sangat terbatas karena tidak stabil dan mudah mengalami degradasi. Stabilitas β-karoten dapat ditingkatkan dengan menggabungkannya dalam sistem penghantaran berbasis emulsi minyak dalam air (o/w). Penelitian ini bertujuan untuk melakukan karakterisasi nanoemulsi β-karoten yang dibuat dengan metode emulsifikasi spontan menggunakan kombinasi tiga surfaktan food grade (Tween 80, Span 40, Span 80), minyak sawit maupun VCO (virgin coconut oil) sebagai fase minyak dengan rasio surfaktan-fase minyak 4.. Penelitian ini juga mengkaji stabilitas fisikokimiawi nanoemulsi β-karoten selama pencernaan di mulut, lambung dan usus dengan menggunakan model digesti in vitro. Hasil penelitian memperlihatkan bahwa nanoemulsi β-karoten yang dibuat dengan fase minyak VCO maupun minyak sawit memiliki pH netral (6,8±0,1), rerata diameter partikel 129–159 nm, distribusi ukuran partikel monomodal dengan nilai indeks polidispersitas (polydispersity index, PdI) rendah (0,214–0,266) dan zeta potensial yang tidak berbeda nyata ([-6,59]–[-8,9]). Nanoemulsi β-karoten dengan fase minyak VCO memiliki rerata diameter partikel yang lebih kecil dibanding minyak sawit sebagai fase minyak. Jenis fase minyak tidak berpengaruh terhadap stabilitas fisik nanoemulsi β-karoten selama simulasi pencernaan di mulut, lambung maupun usus. Nanoemulsi β-karoten dengan fase minyak VCO maupun minyak sawit stabil terhadap pencernaan di mulut maupun lambung. Setelah melewati fase usus, terjadi peningkatan diameter partikel rerata dan perubahan distribusi ukuran partikel dari monomodal menjadi bimodal. Retensi β-karoten dalam nanoemulsi VCO setelah melewati simulasi pencernaan mulut, lambung dilanjutkan fase usus tidak berbeda nyata dengan retensi β-karoten dalam nanoemulsi minyak sawit.

A hydrogel of nanoemulsion system containing mangosteen extract of mangosteen rind was developed and characterized for the purpose of topical formulation. Mangostins, the bioactive in the extract, has been known to have biological activities such as antifungal, antibacterial, antioxidant, antiviral and antitumoral. Due to the hydrophobic nature of mangostins, they can not to be directly formulated into a gel. Oil-in-water nanoemulsions were formulated of virgin coconut oil (VCO) as the oil phase and mixed surfactant consisting of Tween 80 and Span 80, using the high-speed homogenization method. Nanoemulgel formed by mixing the nanoemulsion with aqueous solution of xanthan gum, and added phenoxyethanol as a preservative, was a homogeneous milky white gel. The stability test through accelerated centrifugation and freeze-thaw cycle showed that the nanoemulgel would be stable for at least one year. The nanoemulgel penetrated the skin layer up to 12 μg/cm2 or more than 95% of its total mangostin content, better than the skin penetration result of the nanoemulsion formulation. The present study revealed that VCO-mangostins nanoemulgel formulation is a prospective topical formulation.
