Samuelsson´s research activities have comprised two very different areas: isolation of mistletoe thionins and determination of their amino acid sequences and inventory of medicinal plants used in traditional African medicine and  identification of pharmacologically active compounds in these. The  results have been reported in  94 scientific publications.Samuelsson worked as assistant general secretary at the IUPAC 4th International Symposium on the Chemistry of Natural Products in Stockholm 1966 and in the same position at the 9th International Congress of Biochemistry, 1973, where he also acted as treasurer.

Samuelsson published the first two editions of this book in Swedish in 1980 and  1982. The third edition was translated into English in 1992 when it recieved its present name::Drugs of Natural Origin. Publication of the following editions have all been performed during Samuelsson´s time as Professor Emeritus. All the time the ambition was to keep the book as up to date  as possible which is reflected in the number of pages of the different editions. The third edition comprised 320 pages and the 7th 807. Lars Bohlin started his work as a co-author with the 6th edition.. His contribution is very much appreciated.
