How to extract Caffeine from Tea (Classic DCM Method)

In this method, caffeine is extracted from tea. The type of tea that is used isn't very important (as long as it is caffeinated). The amount of caffeine recovered is small, but this is for fun and not for large yields.

NileRed! You don’t know how much your tutorial videos have helped me and TONS of other ochem students to visualize the labs. We need more lab technique videos, they’re so fun and educational to watch ❤

I'm doing a similar experiment for my chem lab course. This was very helpful in getting a sense of how exactly the set up will actually look. Thanks for sharing the video!

[WickedNick]

Thank you for including an NMR! Nice to see more chem methods to prove a sample.

Hey man just came across your channel today and I freaking love it! Your experiments are so thorough, filmed very well and highly polished! Your channel makes me glad I chose to do chemistry at uni! Take care :D

no wonder chemists get the best coffee 

[ipoint]

Dude this channel is amazing i have been looking for a chemistry channel to follow for quite some time now and your much easier to understand (orally) than NurdRage

My OChem professor is awesome and assigned us this video to prepare for a similar lab, love your videos.

[JDeffenb]

Wow. You actually did a NMR analysis? that's pretty cool that someone like you was able to gain access to a NMR machine like that! Awesome video and keep up the good work!

Yeah, pure Caffeine instead of Coffee in the morning :-)

Neat, I will update my morning coffee routine

I would like to share the method which was done out of curiosity " how is caffeine in colour"I took 5 grams of tea sample and to it I added 500 ml water and kept for boiling.on boiling I added 10 grams of heavy Magnesium Oxide to it and kept for boiling again for 2 hours. Adding water in same not exceeding the 500 ml volume just for the purpose not let the conical dry.then cooled the whole solution and filtered through 201 filter paper.Filtrate was 500 ml.I then took 200 ml filtrate and added 20 ml Sulphuric acid (2 ml sulphuric acid : 18 ml water).Took the whole solution in separating funnel and extracted 6 times with chloroform.combined all these layers of chloroform and kept on water-bath till whole chloroform evaporates.And here I get white coloured caffeine in good amount.Thank you!!

Awesome iv been waiting for this one for a while !!! Always looking forward to more!!

Have you tried extracting caffeine from soda pop with the same method? Basically just do a liquid-liquid extraction with a high-caffeine drink like Mountain Dew.

I really like your videos. Keep up the good work.

[chakeson]

Nice work! You should do more caffeine related work!

[maximianocoelho]

Guess what am I extracting from tea today....Thanks man, it was a huge help.

[alessandrostagno]

Thanks for the video, i made it at school, but isn't so clean and pure.

[tommasopetrella]

I have done this experiment using Chloroform as it was easier for me to obtain.  It worked great and my final product was white and very pure.  I don't know which would remove more caffeine, Chloroform or Dichloromethane, but I am sure the difference is negligible.

So I followed your procedures to extract the caffeine from tea. I ran my caffeine through a 60MHz 1H NMR and I am seeing the normal caffeine peaks. However, I also see a peak around 1.75 ppm. Do you have any idea what this contamination may be?

Hypothetically this is exactly how you extract DMT * Joe Rogan wants to know your location*

Helio my friend, your videos are amazing. You are a very gifted chemist. I have a suggestion for a video for you and I don't know how to contact you so please excuse me here. There is a huge market for e-cigarette devices right now and regulations are now implemented in the US which classify all cigarette products is a tobacco product. my suggestion is that because e-cigarette juices and components will become very difficult to buy, maybe you could help with one of the biggest problems. The nicotine used in the E-Cigarette liquid is extracted from tobacco plants and comes in various strengths, the most popular being 100 milligrams per milliliter which is then further diluted with PG and vegetable glycerine. Would you be willing to do a video about how somebody could use tobacco leaves to extract the nicotine and have it dissolved in propylene glycol? Thanks again from a fellow Canadian.
