Response to Wiart, C. Lee et al., Inhibitory effect and mechanism of antiproliferation of isoatriplicolide tiglate (PCAC) from Paulownia coreana. Molecules 2012, 17, 5945-5951: a note regarding Paulownia coreana. Molecules 2013, 18, 2587-2588.

In a Comment recently published in Molecules [1], Prof. C. Wiart took issue with our identification of the plant species used in our work as Paulownia coreana. Although this name was assigned by H. Uyeki in 1925 [2], appears as such in handbooks of Korean flora [3], and examples of its use can be found in the recent literature [4–9], after reviewing the arguments and references presented in [1], we now recognize that this is no longer considered an accepted species name, and therefore we wish to revise our assignment to Pauwlonia tormentosa (Thunb.) Steud. We thank Prof. Wiart for bringing this fact to our attention and apologize to the readership of Molecules for any confusion caused by our previous classification of the species.
