“…The root of E. grijisii (commercial Chinese name: Yuzhou Loulu) is listed in "Chinese Pharmacopeia" and is used to clear heat, expel miasma and stimulate milk secretion (National Pharmacopoeia Committee, 2005). Previous chemical investigations on the root of E. grijisii demonstrated the presence of essential oil (Guo et al, 1994) and thiophenes (Guo et al, 1992;Koike et al, 1999;Lin et al, 1999;Liu et al, 2002), which have been proven to possess several activities, like antitumour (Lambert et al 1991;Marles et al, 1992), insect (Nivsarkar et al, 1991;Sharma and Goel, 1994), antivirus (Hudson et al, 1993;Marles et al, 1992) and anti-infl ammatory (Lin et al, 1992).…”
