Abstract

Background: Premature aging is a serious problem, especially for women. Skin aging is mainly caused by solar radiation. Ultraviolet (UV) A and B rays from sunlight induce the formation of reactive oxygen species in the skin and cause oxidation. Antioxidants are compounds that can neutralize free radicals by slowing down oxidation reactions. Maggots are widely consumed by the public and used as topical medicines because they have high levels of lauric acid, which acts as an anti-inflammatory, antibacterial, and antiprotozoal. Purpose: to analyze the formulation of nanocream preparations, antioxidant activity and evaluate the physical stability of maggot extract nanocream. Research method: The method used was the maceration method with n-hexane, antioxidant testing using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method, and testing the physical stability of the preparation. The results of the antioxidant activity test showed an IC50 value of maggot extract of 40.36 ± 1.21 µg / mL. Results: It shows that the sample has very strong antioxidant activity. Based on the organoleptic test, the nanoceram preparation in Formula 1, 2, 3 and 4 has a milky white color which is influenced by the difference in the amount of extract, a distinctive aroma and semi-solid consistency. The pH examination of nanocream preparation must be adjusted to the skin pH, which is 5-7. The results of the viscosity test on the maggot extract have met the requirements, which are 2,000-5,000 cps. Conclusion: formulation and evaluation of the nanocream extract meet the requirements as a good nanocream and have the ability as an anti-aging.

Abstract

Asam Urat merupakan penyakit yang paling banyak dialami oleh masyarakat Indonesia. Allopurinol sebagai inhibitor spesifik dari enzim canthin oksidasi (XO) terbukti efektif dalam menurunkan kadar asam urat, tetapi efek sampingnya dapat menyebabkan gagal hati, hepatitis, hiperbilirubinemi, diare serta mual muntah. Penelitian ini bertujuan untuk mengetahui potensi pemberian Ekstrak Etanol Biji Mahoni (EEBM) (Swientenia macrophylla) terhadap penururnan kadar asam urat pada tikus. Metode penelitian secara in vivo dengan penginduksi potassium oxonate dan jus hati ayam pada tikus. Sebanyak 5 kelompok tikus (Na-CMC 0,5%, tablet Allopurinol 3,6 mg/kgBB, EEBM (125, 250,375 mg/kgBB)) dilakukan selama 14 hari. Hasil uji ANOVA (p<0,05) menunjukkan adanya perbedaan rerata yang bermakna antara pretes 9,980 mg/dL dan postes  6,612 mg/dL sehingga EEBM berpotensi terhadapat penurunan kadar asam urat dalam darah tikus dengan jumlah rata-rata penurunan 3,392 mg/dL. Penurunan kadar asam urat tersebut diduga karena adanya kandungan senyawa flavonoid. Senyawa tersebut merupakan inhibitor xantin oksidase terkuat karena disebabkan oleh adanya gugus hidroksil C5 dan C7 selain itu, disebabkan juga oleh adanya C2 dan C3 sehingga lebih memudahkan interaksi dengan xantin oksidase. Mekanisme utama dari flavonoid berupa aktifitas inhibitor enzim dan antioksidan untuk radikal bebas.
