Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires only small quantities of material. Separations in paper chromatography involve the principle of partition.
Paper chromatography of some spinach leaf extract shows the various pigments present in their chloroplasts: yellowish xanthophylls, greenish chlorophylls a and b. (from Botany ) Image 34 The lycopod Isoetes bears microphylls (leaves with a single vascular trace).
40% of the leaf mass typical for the variety reached 45: 50% of the leaf mass typical for the variety reached 46: 60% of the leaf mass typical for the variety reached 47: 70% of the leaf mass typical for the variety reached 48: 80% of the leaf mass typical for the variety reached 49: Typical leaf mass reached 5: Inflorescence emergence 51
Planar chromatography is a separation technique in which the stationary phase is present as or on a plane. The plane can be a paper, serving as such or impregnated by a substance as the stationary bed (paper chromatography) or a layer of solid particles spread on a support such as a glass plate (thin-layer chromatography).
It grows as a trailing undershrub with thick, pale, furry stems, and thick, oval, saddle-shaped leaves 10-60 millimetres long and 5-30 millimetres wide. Flowers occur in clusters of three to five, and comprise four light yellow perianth segments surrounding a centre of many stamens. [ 2 ]
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.
P.S. The only argument I want to leave here, is that when an extraction of a spinach leaf is made on chromatography paper, the green colored part contains chlorophyll. If the chlorophyll would transmit green light would we say that it is the white paper that reflects the green light transmitted by chlorophyll?
Spinach (Spinacia oleracea) is a leafy green flowering plant native to central and Western Asia. It is of the order Caryophyllales, family Amaranthaceae, subfamily Chenopodioideae. Its leaves are a common edible vegetable consumed either fresh, or after storage using preservation techniques by canning, freezing, or dehydration.
