Seven new sesquiterpenoid glycosides, consisting of one thapsan-type (1), two capnellane-type (2 and 3), four floridanolide sesquiterpene glycosides (4-7), and one new azulene-type sesquiterpene (8), along with six known sesquiterpenes (9-14) were isolated from the roots of Illicium henryi. The structures of 1-8 were elucidated by extensive spectroscopic analyses and chemical methods. The absolute configurations of 1, 2, and 8 were determined based on Rh-2(OCOCF3)(4)-induced CD, Mo-2(OAc)(4)-induced CD data, and calculated electronic circular dichroism (ECD), respectively. Compound 1 was found to exhibit weak neurotoxicant activity.
