Muurolane sesquiterpenes from illicium tsangii
A dichloromethane extract of Illicium tsangii has yielded five novel muurolane sesquiterpenes (1, 2, 6, 7, 9) and three new menthane monoterpenes (10-12) in addition to several known compounds. Biogenetic relationships among the sesquiterpenes are discussed.
