Friedlieb Ferdinand Runge - The first scientist in the world to successfully break down caffeine
The world knows Friedlieb Ferdinand Runge thanks to the successful separation of the world's first caffeine in 1819.
On October 3, 1981, Friedlieb Ferdinand Runge's close friend Johann Wolfgang von Goethe (1749-1832), a famous German poet who was dubbed the "great man of world literature" , gave Give scientists a packet of coffee beans. At that time, this was an extremely valuable item.
Following Von Goethe's wishes after seeing his friend Friedlieb Ferdinand Runge successfully extract "poison" to dilate pupils from Atropa belladonna, the German scientist continues to research the composition. chemistry of coffee beans.
A few months later, Friedlieb Ferdinand Runge fully determined the composition of the beans, thus successfully separating the caffeine ingredient for the first time in 1819.
The scholar had the last days of his life
Portrait of German scientist Friedlieb Ferdinand Runge (February 8, 1794 - March 25, 1867).
German analytical chemist Friedlieb Ferdinand Runge was born on February 8, 1794 in Hamburg, Germany.
After taking his doctorate and acting as a professor at Breslau University in 1831, Runge continued to experiment - then wrote two books in which he described the use of techniques to separate chemical components.
After leaving the university, Runge moved to work at a chemical factory in Oranienburg. Here he studied synthetic dyes.
In addition to becoming a pioneer in how to dye new clothes, Runge also identifies and names the ingredients of dyes, including carbolic acid, now known as phenols; and discovered how to extract sugar from sugar beet juice.
After years of hard work, he was suddenly fired by his manager while angry. This greatly influenced the life of the multi-talented scientist later. After 15 years of living in poverty, Friedlieb Ferdinand Runge died at the age of 73.
On March 25, 1867, the world lost a scientist who successfully extracted the first caffeine, made the first coal tar, chromatography (one of the analytical techniques commonly used in laboratories. of analytical chemistry used to separate substances in a mixture .
So far, after more than 200 years, Google has designed images to commemorate and honor the great merit of the German scientist thanks to his contributions in the field of chemistry.
Something about caffeine
Caffeine has the chemical formula C8H10N4O2. This is a substance found in coffee beans, later found in tea, kola nuts, guarana and cocoa beans.

According to the scientists' analysis, caffeine affects the human body in many different ways.
First, with a sufficient amount of caffeine, it stimulates the central nervous system; create excitement, reduce sleepiness; works to relieve pain, reduce fatigue during physical training .
Secondly, when using caffeine continuously, it will turn into inhibitory stage, causing heart palpitations; stimulating the respiratory center to cause bronchiectasis; affect bone and joint health; affect the stomach; and increase blood sugar .
