Berry leaves are byproducts of berry cultivation; their traditional therapeutic use against several diseases, such as the common cold, inflammation, diabetes, and ocular dysfunction, has been almost forgotten nowadays. Nevertheless, the scientific interest regarding the leaf composition and beneficial properties grows, documenting that berry leaves may be considered an alternative source of bioactives. The main bioactive compounds in berry leaves are similar as in berry fruits, i. The leaves are one of the richest sources of chlorogenic acid.
Then About mg of each of the four known compounds will be added to the appropriate test tube, and mg of the unknown will be added to the test tube marked 3-unk. The test tube with unknown will receive 1.
Any insoluble material will be allowed to settle. Capillary tubes will be used to spot the samples of 1-asp, 2-ace, and 3-unk on the coated side of one plate.

The spots are to be evenly spaced, 0. The plate will be viewed under UV light to make sure that enough of each sample has been applied.
Capillary tubes will also be used to spot 3-unk, 4-caf, and 5-ibu on the other plate in the same manner. Again, UV light will be used to make sure enough of each sample has been applied. Then, each TLC plate will be placed spotted end down into a developing jar containing a pool of ethyl acetate that is about 0.
The jar will be capped and when the ethyl acetate rises within cm of the top of the TLC plate, the TLC plate will be removed from the jar and allowed to dry. Once dry, the TLC plate will be analyzed under the UV light and the appearance of the spots will be drawn in a laboratory notebook.
Data First, five clean test tubes were labeled 1-asp, 2-ace, 3-unk, 4-caf, and 5-ibu. A spatula was used to help mix any solids that were having trouble dissolving. Micro capillary tubes were used to spot 1-asp, 2-ace, and 3-unk on the coated side of one plate.
The spots were evenly spaced and about 1 cm from the bottom of the plate and 0. On the second plate, 3-unk, 4-caf, and 5-ibu were plated in the same manner.
The plates were then placed spotted side down in a developing jar that contained a 0. The lid of the jar was screwed on and the plates were allowed to sit in the jar until the ethyl acetate rose to about 2 cm from the top of the plate.
The plates were then removed from the jar and then analyzed under an ultraviolet light. The appearance and measurements of the spots were recorded in a lab notebook.Published: Mon, 5 Dec In this experiment I have investigated the research question – How does the process of recrystallisation improve the purity of Aspirin.
