"Aktivitas antioksidan, antikanker, dan antiinflamasi adalah beberapa manfaat farmasi yang dimiliki oleh polifenol alami seperti α-mangostin dan asam ferulat. Namun, sifat hidrofobik senyawa ini membuatnya sulit larut dalam air, sehingga ekstraksinya harus dilakukan dengan pelarut khusus. Seringkali, pelarut organik tradisional menimbulkan masalah lingkungan dan risiko kesehatan. Hydrophobic Deep Eutectic Solvent (HDES), yang terdiri dari asam dekanoat dan asam dodekanoat, menawarkan alternatif yang ramah lingkungan dengan tekanan uap rendah dan efisiensi ekstraksi tinggi terhadap senyawa lipofilik. Metode ekstraksi ultrasound-assisted extraction (UAE) meningkatkan efisiensi dengan waktu optimal dua jam. DES stabi pada rasio molar 1:2, 1:3, dan 1:4. Kandungan airnya antara 0,81 dan 0,95%, dan viskositasnya antara 10,27 dan 12,31 cSt. Kandungan α-mangostin dan asam ferulat yaitu 7,99 mg/ml dan 0,04 mg/ml. Yield α-mangostin dan asam ferulat yaitu 239,68 mg/g dan 1,33 mg/g. Kandungan fenolik total ekstrak manggis adalah 19,6 mg GAE/g simplisia dan 2,57 mg GAE/g simplisia. Selama dua belas bulan, emulsi tetap stabil dengan ukuran droplet 0,319–0,42 μm dan zeta potensial negatif tinggi -49,5 dan -52,5 mV. uji disolusi pada medium SIF menghasilkan konsentrasi yang lebih rendah daripada di air. Formulasi obat lipid yang dihasilkan cukup baik dan berpotensi sebagai suplemen.
Antioxidant, anticancer, and anti-inflammatory activities are some of the pharmaceutical benefits possessed by natural polyphenols such as α-mangostin and ferulic acid. However, the hydrophobic nature of these compounds makes them poorly soluble in water, so their extraction must be done with specialized solvents. Often, traditional organic solvents pose environmental concerns and health risks. Hydrophobic Deep Eutectic Solvent (HDES), which consists of decanoic acid and dodecanoic acid, offers an environmentally friendly alternative with low vapor pressure and high extraction efficiency towards lipophilic compounds. The ultrasound-assisted extraction (UAE) method increases the efficiency with an optimal time of two hours. DES was stable at molar ratios of 1:2, 1:3, and 1:4. Its water content was between 0.81 and 0.95%, and its viscosity was between 10.27 and 12.31 cSt. The content of α-mangostin and ferulic acid were 7.99 mg/ml and 0.04 mg/ml. The yields of α-mangostin and ferulic acid were 239.68 mg/g and 1,33 mg/g. The total phenolic content of mangosteen extract was 19.6 mg GAE/g simplistic and 2.57 mg GAE/g simplistic. For twelve months, the emulsion remained stable with a droplet size of 0.319-0.42 μm and a high negative zeta potential of -49.5 and -52.5 mV. Dissolution tests on SIF medium resulted in lower concentrations than in water. The resulting lipid drug formulation is quite good and has potential as a supplement."
