From the very beginning of cultivation Betel leaf is cultivated in Bangladesh. As a tradition of regular habit a large number of people chew betel leaf. As the daily life of people betel leaf and betel nut have possessed a special place in our literature, song, society and cult
Thin Layer Chromatography
Thin Layer Chromatography or TLC is a technique used as a separation and identification technique. There are many forms of chromatography, but one thing that remains constant throughout all of the types of chromatography is that there is a stationary phase an

How can you tell pigment separation by using Chromatography?
To prepare a chromatogram, separate pigments in a leaf and interpret the chromatogram.
If I am to put a chromatography paper into a solvent, then it would separate the pigments depending on their Rf va
Hypothesis: My hypothesis for this experiment, the study of the effects of different wavelengths on leaf pigments, if chlorophyll a absorbs blue-violet light, chlorophyll b absorbs blue light, carotene absorbs blue-green light, and xanthophyll absorbs blue light, then wavelengths o
Paper chromatography is a method using a chromatography paper to identify the many mixtures of one simple color. The word chromatography comes from the Greek words, "chroma," meaning color, and "grafein," meaning to write. The process of this experiment is to place a colored dot, such
Chromatographic Analysis of a Commercial Analgesic’s Active Component
This study on Chromatographic Analysis of a Commercial Analgesic’s Active Component seeks to separate, identify, quantify and analyze the active component found in Biogesic®, which may be useful for public awa
To use the process of chromatography to separate plant pigments.
To compare the plant pigments found in spinach and red leaf lettuce leaves.
I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a hig
In the present time, the rate of proliferation of diabetic people is continuously and rapidly increasing. Further studies show that the number of diabetes cases worldwide has doubled since 1980 and is now at startling 350 million diabetics. (Laino, 2011). Diabetes is a li

Problem: Why do leaves change color in the fall?
Background: Leaves contain many pigments such as chlorophyll b, xanthophyll, and beta carotene besides chlorophyll a. They are part of the photosystem in the thylakoids. Pigment molecules can be separated by a procedure called...
Separation and identification of components of a mixture was determined by using Chromatography. The components of a mixture have different affinities for a stationary phase as well as different affinities for a mobile phase.
An extremely common technique by using two chem
Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a sol
Basal Leaf Removal
By: Jonathan Klein
Wine grape vineyards are commonly using a process of basal leaf removal to improve fruit zone light microclimates. There has been also practice of pre-bloom removal; but as we all know, it really comes down to the cost and how much money you spe
