Emeritus Professor
Takuo Okuda
Okayama University
Takuo OKUDA, Emeritus Professor of Okayama University. He graduated from Kyoto University in 1951 (B.Sc), and received PhD from Kyoto University in 1955. After he studied at Pennsylvania University as the Visiting Scholar until 1958, he was appointed as the Assistant Professor of Kyoto University in 1958, and then as the Associate Professor of Kyoto University in 1962. He moved to Okayama University as the Full Professor in 1970, and continued his work there until 1993. His works in natural product chemistry are in the wide range from terpenes such as coriamyrtin, sugars such as coriose, to tannins including dehydroellagitannins and oligomeric ellagitannins.


Emeritus Professor
Takashi Yoshida
Okayama University
Takashi YOSHIDA, Emeritus Professor of Okayama University. He received his BSc in Gifu Pharmaceutical University in 1962, MSc from Kyoto University in 1964, and PhD from Kyoto University in 1969. His research as a faculty staff started as Research Associate at Kyoto University in 1965. He moved to Okayama University as Associate Professor in 1970. He continued his study as Professor, Okayama University (1993-2005). Then, he worked at Matsuyama University as Professor until 2012. He received 6th Tannin Award in 2008. His research includes isolation and characterization of bioactive polyphenols, especially hydrolyzable tannins in medicinal plants, and he published 280 original papers and 45 review articles concerning his phytochemical and pharmaceutical research on tannins and related polyphenols.


Visiting Professor
Tadao Kondo
Nagoya University
Tadao KONDO, a visiting Professor of Nagoya University, received his B.Sc. (1965) from Gifu Pharmaceutical University, MS (1967) and then PhD (1973) from Nagoya University (under Prof. Toshio Goto). After a post-doc stay in University of Alberta (1973–1975) he became a Research Associate (1979) and an Associate Professor (1993) at the Chemical Instrument Center, then a Professor (2000) at the Graduate School of Bioagricultural Sciences, Nagoya University. Prof. Kondo is a leading authority of anthocyanin chemistry. He achieved a methodology of purification and structural determination of complex anthocyanins in blue flowers and reported many publications. For these works he received The Chemical Society of Japan Award for Creative Work (1998). He and his group has been presented papers at ICP from 1990 and still very active in research.

A unified strategy for the synthesis of highly oxygenated diaryl ethers featured in ellagitannins
Nat. Commun., 2014, 5:3478, doi: 10.1038/ncomms44781-10
Ellagitannins are a family of polyphenols containing more than 1,000 natural products. Nearly 40% of characterized ellagitannins contain a highly oxygenated diaryl ether that is one of the most critical elements to their structural diversity. We reported a unified strategy for the synthesis of highly oxygenated diaryl ethers. This strategy enabled the synthesis of different diaryl ethers. The first total synthesis of a natural ellagitannin bearing a diaryl ethers was also performed. This work potentially increases the number of synthetically available ellagitannins in an innovative manner.
