Amphetamine and methamphetamine are central nervous system stimulants used to treat a variety of conditions. When used recreationally, they are colloquially known as "speed" or sometimes "crank".[1] Amphetamine was first synthesized in 1887 in Germany by Romanian chemist Lazăr Edeleanu, who named it phenylisopropylamine.[2][3][4] Around the same time, Japanese organic chemist Nagai Nagayoshi isolated ephedrine from the Chinese ephedra plant and later developed a method for ephedrine synthesis.[note 1][6] Methamphetamine was synthesized from ephedrine in 1893 by Nagayoshi.[7] Neither drug had a pharmacological use until 1934, when Smith, Kline & French began selling amphetamine as an inhaler under the trade name Benzedrine for congestion.[8]

An improved analytical depolymerization method for characterizing condensed tannins was developed with menthofuran (3,6-dimethyl-4,5,6,7-tetrahydro-1-benzofuran) as the nucleophilic trapping reagent. Herein, menthofuran was compared with routinely used nucleophiles, phloroglucinol and 2-mercaptoethanol. At 30 °C and in the presence of 0.1 M HCl, menthofuran displayed the outstanding ability to enable the fast and full depolymerization of procyanidin B2 using only a 1:1 molar ratio of both reactants. Under the same conditions, phloroglucinol and 2-mercaptoethanol led to a reaction equilibrium with significantly lower conversion yields. Application to commercial tannin extracts showed that a menthofuran-to-extract weight ratio of 1 gave the same yields of procyanidin constitutive units as 10-fold higher molecular equivalent phloroglucinol and 100-fold 2-mercaptoethanol. Finally, guidelines for implementing the menthofuran depolymerization method are proposed to assess the tannin content and composition of extracts as well as of plant materials without prior extraction.
