“…I. obliquus is traditionally taken mainly in the form of a hot water extract; however, some significant differences can exist between the chemical compositions of hot water and ethanol extracts (Hu et al, 2009). In recent years, more than 20 different kinds of bioactive components have been found in I. obliquus, including triterpenoids, polyphenols, steroids, b-glucan, peptides, and polysaccharides, suggesting a high medicinal value and good prospects for market development (Hu et al, 2009;Song et al, 2013). Triterpenoids such as inotodiol, lanosterol, and trametenolic acid are considered the main antitumor ingredients being able to induce growth inhibition, cell cycle arrest, and apoptosis in different cancer cells; however, the exact molecular mechanisms by which these effects occur are still not well understood (Chung et al, 2010;Du et al, 2011;Nomura et al, 2008;Youn et al, 2009;Zhong et al, 2011).…”
