Paper chromatography is a technique that involves placing a small dot or line of sample solution onto a strip of chromatography paper. The paper is placed in a container with a shallow layer of solvent and sealed. As the solvent rises through the paper, it meets the sample mixture, which starts to travel up the paper with the solvent.

Its leaves are a common edible vegetable consumed either fresh, or after storage using preservation techniques by canning, freezing, or dehydration.
Paper chromatography of some spinach leaf extract shows the various pigments present in their chloroplasts: yellowish xanthophylls, greenish chlorophylls a and b. Plants and various other groups of photosynthetic eukaryotes collectively known as "algae" have unique organelles known as chloroplasts.
The young shoots and leaves of Chenopodium giganteum can be eaten cooked like spinach, another member of the Amaranthaceae. Most of the oxalic acid and saponins are removed during the cooking process, especially if boiled for 2 minutes at 100 °C (212 °F). [11] [12] However, the leaves are also edible raw in lower quantities, for example as a ...
The alternate leaves consist of a petiole and a simple blade. The basal leaves are often forming a rosette. The leaf blade is triangular-hastate to ovate, sometimes with elongated lobes, with entire or dentate margins and an acute apex. [1] [2] The plants are usually dioecious, (rarely monoecious). The male flowers are in glomerules forming ...
