For decades, the Martian regolith has stymied robotic mission efforts to catalog the organic molecules present. Perchlorate salts, found widely throughout Mars, are the main culprit as they breakdown and react with organics liberated from the regolith during pyrolysis, the primary extraction technique attempted to date on Mars. This work further develops subcritical water extraction (SCWE) as a...

Subcritical water extraction of horse chestnut (Aesculus hippocastanum) parts, such as seeds, seed shell, bark and leaves has been performed in a batch reactor at temperatures 150, 200 250?C times 5, 15 30 min. The obtained extracts were analyzed by spectrophotometric methods to determine the total phenols, carbohydrates antioxidant activity. Furthermore, compounds detected extracts, triterpene...

The dumping of waste banana peels from local chip manufacturing has encouraged sustainable food trends to valorize these as pectin sources. In this study, soluble was extracted using a continuous subcritical water extraction system (SWE). This method promising fast process with solvent that environmentally friendly. Temperature (100 160 °C) and time (5 50 minutes) were manipulated, fixed pressu...

Subcritical water extraction (SWE) is an alternative technique that implement water as a solvent. The objective of this work was to compare the efficiency of SWE in temperature range from 100ºC to 180ºC at extraction times ranging from 5 to 25 minutes with an ethanolic soxhlet extraction in terms of total phenolic content (TPC), total flavonoid content (TFC) and radical scavenging activity (RSA...
