ABSTRACT
Five sesquiterpenoids, 1α,8α-epidioxy-4α-hydroxy- 5αH-guai-7(11),9-dien- 12,8-olide. (1), 8,9-seco-4ß-hydroxy-1α,5ßH-7(11)-guaen-8,10-olide (2), 8α-hydroxy-1α, 4ß,7ßH-guai-10(15)-en- 5ß,8ß-endoxide(3), 7ß,8α-dihydroxy-1α,4αH-guai-10(15)-en-5ß,8ß-endoxide(4) and 7-hydroxy-5(10),6,8-cadinatriene-4-one(5), together with seven known analogs were isolated from the rhizomes of Curcuma wenyujin. Their structures and relative configurations were determined on the basis of spectroscopic methods including 2D NMR techniques, and the structures of 1 and 2 were confirmed by single-crystal X-ray diffraction experiment. Compounds 1-10 and 12 showed significant in vitro antiviral activity against the influenza virus A with IC50 values ranged from 6.80 to 39.97 µM, and SI values ranged from 6.35 to 37.25.
