The structure of inflexin isolated from Rabdosia inflexa(THUNB.)HARA was re-examined by means of 1H two-dimensional correlated spectroscopy(1H-COSY)and nuclear Overhauser effect (NOE)experiments,and was revised to 1 from the previously reported structure,2.The structures of the chemically correlated diterpenoids,inflexinol and inflexanin B were also revised to 3 and 4, respectively.
