“…Chen et al (2007) [ 31 ] found that, in comparison with shaking extraction, supercritical fluid carbon dioxide extraction, heat reflux extraction, and ultrasound-assisted extraction, microwave-assisted extraction had the highest efficiency in extracting total triterpenoid triterpenoids from Ganoderma atrum [ 30 ]. However, a previous study suggests that cucurbitane-type triterpenoids, such as 3β,7β,25-trihydroxycucurbita-5,23 (E)-dien-19-al and momordicine I, were extremely sensitive at 100 °C [ 22 ]; hence, temperatures below 100 °C are recommended for such compounds through the microwave-assisted extraction technique.…”
