~Motive~ We listened to our seniors’ study “Making chemical-free fertilizer with plant components” and we will extract component from plants to find good applications for our life.
~Research Material~ Cinnamon Cork Tree Bracket fungus Chaga Rooibos
Cinnamon Cork tree ・Spice ・We say it has hyperthermicaction. ・Rutaceae Rooibos ・we say it is a medicine of perpetual youth and long life ・It has antioxidant action
Chaga Bracket fugus ・Shelf-type mushrooms ・It is born in the stem of natural trees, fallen trees, and dead trees ・Cold-resistant mushroom ・It is born in cold areas
Bracket fugus and Chaga are relatives. But both of them are different in trees. Do they have different components!?
~First Experiment ~ Crushmaterial with ethanol using a machine. Leave it forthree weeks. Concentrate it. Add water to it, to get n-Hexane Extracts.
~Thin Layer Chromatography(TLC)~ ~Method~ ①Make 10ml of solution which is 90% Chloroform and 10% Methanol (we will just call it “the solution” after this), and make a sample with the solution. Vacuum Filtration Concentration
②Spotthebottom of the TLC plate with the concentrate from step ①. Then, we put 5ml of the solution into a glass case and we put the TLC into the case.
③After the solution rises enough, check if you can see component spots withUVlight.
~Results of Experiment~ The line of rising solution Ⅲ Bracket fugus ⅠCinnamon Ⅱ Rooibos ⅣCork tree, Chaga …The first spot …Spots of components (A thicker mark means the component is more concentrated.)
~Column Chromatography~ ~Method~ ① Make 200ml of the solution ② Put Silica gel and the solution into an Erlenmeyer flask and mix them. Chloroform Methanol Silicagel
③ Put ② into a column and pour in a little solution. • After that we put 5ml of the solution mixed with a sample into the Column .
④ Put a little Silica gel on ③and pour little by little another 200ml of the solution. Mixed Silica gel and 5ml solution → Expand → Silica gel →Sample →Solution
⑤ Divide the liquid into 2 equal parts, put in a Flask and concentrate them.
Result of Experiment • Ⅰ:Cinnamon
Ⅱ:Rooibos R-0 R-1 R-2
Ⅲ:Bracket fungus S-1 S-2 S-3 S-4 S-5 ※There is not S-0 picture.
C-1 C-2 C-3 R-1 R-2 S-1 S-0, 2~5 R-0 C-0 Ⅰ Ⅱ Ⅲ • ……The first spot • …Spot of components (a thicker mark means the spot is more concentrated)
~Consideration~ Cinnamon ・C-2 has a strong C-0 smell ⇒We think C-2 has fragrance components. ・C-3 has C-0 color ⇒We think C-3 has color components. • Rooibos ・R-2 is like C-0 color ⇒We think R-2 has color components. • Bracket fugus • ・S-2 is like S-0 smell • ⇒We think S-2 has fragrance components.
~Future Activities~ ・Try to do other experiments . ・Try to extract component of other plants. ・Conduct experiments to test the effects of components. We will examine whether Rooibos have inhibits UV light and so on.
