Sintesis Nanoemulsi dari Ekstrak Kulit Manggis dengan Metode Energi Tinggi

Mangosteen (Garcinia mangostana L.) has become the main agricultural products contributing to largest annual foreign exchange from fruit category. rind contains xanthone compounds as a source of antioxidants, with α-mangostin and γ-mangostin, components which are used traditional modern ingredients treat various diseases. However, mangosteen extract low bioavailability thus resulting in effectiveness application. This study aimed find ideal formulation for producing nanoemulsion peel. The research carried out two stages: extraction peel production nanoemulsion. Ethanol 70% was best extraction, percentage yield 40.96±0.51%, antioxidant activity 5708.33±159.57 µg AEAC/mL sample, total xanthones 373.84±6.49 µg/mL sample. use Tween 20 at gave test results, particle size 10.58±1.25 nm, polydispersity index 0.27±0.03, zeta potential -2.34±0.46 mV, 35,28±0,04
