The goal of present study was to investigate kinetics of supercritical carbon dioxide (SC CO2) extraction of essential oils from dried clove buds and oregano leaves. Total extract yields after exhaustion of plant material at 10 MPa and 40°C (after consumption of 94.3 kgCO2/kg plant material) were 18.2% and 1.0 %, respectively. Synergistic effect in the extraction process was also investigated u...
There are many reports on biological activities of pentacyclic triterpenoids, which could be relevant to the pharmacological effects including anti-inflammatory properties. Dandelion (Taraxacum officinale Wiggers et Weber, Asteraceae) is one of the best known European medicinal plants, rich in triterpenoids, which has been used for the treatment of various inflammatory diseases such as rheumato...
We designed and developed a system to efficiently extract dissolved inorganic carbon (DIC) from seawater and groundwater samples for radiocarbon dating. The Rapid Extraction of Dissolved Inorganic Carbon System (REDICS) utilizes a gas-permeable polymer membrane contactor to extract the DIC from an acidified water sample in the form of carbon dioxide (CO2), introduce it to a helium gas stream, c...
