This is an experiment to separate the various pigments found in green plants, using a popular and simple technique called Paper Chromatography.
Dear viewer/subscriber, if my videos helped you a lot (maybe you aced your exams as a student, or you won the admiration and full attention of your students as a teacher, or you got your techniques right as a hobbyist), then its my humble request if you could take a moment to consider supporting me on anyone of the following platforms:

Thank you for this video! Is very helpfull! I have two questions, what plant did you use? I'm reading an article where the xanthophyll has a Rf of 0.16 (it seemed very polar to me) is it possible that the differences between your experiment and the experiment from the article (they used spinach) in the xantophyll are because there are many types of xanthophylls (like lutein and violaxanthin) in different plants? Or why did the xanthophyll in the spinach stood behind chlorophyll b and yours didn't?

Hi, you can try leaves of different colours and shades. I've also seen some videos where they separate the pigments contained in ink. You can also separate amino acid components in a protein rich food source. Although they will need a visualizing agent to be sprayed on to them and then slightly heated to be able to see the amino acid spots on the paper. But for this u will need Ninhydrin (a potent carcinogen) so i highly doubt if thats the right thing for a sc fair projct. So u can work on Leaves and inks. Good luck 👍 i'm here if u need help.

At 5:54 I just had a question Can I say that the first pigment spot which has been mentioned as chlorophyll b does it contain only the pigment chlorophyll b or it is a mixture of all the other pigments as well and gradually only carotene is left
@TheSingtangpaScienceGuy
@TheSingtangpaScienceGuy 3 года назад
Each spot is a single phytopigment. From the first spot (chl b) the remaining pigments except chl b will migrate to the second spot (chl a spot). From second spot, all other pigments except chl a will migrate further up to the third spot and so on. This groups migration and the leaving behind of one pigment type at each "stop/station" will continue until all the pigments have been resolved into different spots on the paper.

@TheSingtangpaScienceGuy
@TheSingtangpaScienceGuy 4 года назад
You can perhaps use a mix of leaves of different colors; green, red, yellow, orange...... Or you can use a mix of different coloured inks. Never actually tried these "fun" experiments before though. Good luck 🙂 do lemme know the results. 👍🏾

@TheSingtangpaScienceGuy
@TheSingtangpaScienceGuy 3 года назад
@@vishesharrvansashitharan3593 its probably because the leaves from which you prepared the extract, are still young, green and actively photosynthesizing. Pheophytin, as you might have already known, is one of the breakdown intermediate products of chlorophyll, and this breakdown into pheophytin, takes place usually during leaf senescence. So, even if the fresh green leaf might contain a little bit of pheophytin, the quantity is not so much as to to be seen on a chromatogram. Ofcourse, if you do a spectrophotometric analysis , you will detect some amount. But If, for any reason, you still want to see pheophytin on the paper, you can acidify the leaf extract prior to loading on the paper, in that way the chlorophylls lose their Magnesium and become pheophytin. Or you can make a leaf extract from old, senescing leaves that have yellowed. You are sure to find a nice pheophytin band/spot from old leaves. This is all i know from my textbook knowledge. Correct me if i'm wrong. Goodluck.
