Mangrove is the most productive ecosystem in marine environment, as it provides a unique habitat opportunity for many marine species and key goods and services for human beings. In Indonesia, mangroves are still considered as underexploited marine resources, and functional materials from Indonesian mangroves are not characterized yet. In this study, two mangroves Sonneratia alba and Rhizhophora mucronata from Kendari, were hydrolyzed using the subcritical water extraction (SCWE) system. Three different temperature conditions (150–230 °C with 40 °C increments) were applied to obtain the best functional materials. Mangroves hydrolysate was further analyzed for total sugar, protein, phenol content. The antioxidant capacity and functional material contents varied significantly based on the sample materials and extraction conditions, with R. mucronata hydrolyzed at temperature 230 °C showing the highest antioxidant activity. High-performance liquid chromatography (HPLC) analyses revealed high contain of phenolic acids in all mangroves hydrolisates especially R. mucronata fruit (RMF). Collectively, this study shows the potential of mangroves resources in Indonesia in Indonesia for different applications (food, cosmetics and pharmacy) using environmental friendly technology.
