설명

일반 설명

Chlorophyll a belongs to the class of porphyrins conjugated with magnesium. It is one of the major forms of oxygenic photosynthetic pigment, chlorophyll, that converts light energy in the blue and red parts of the visible region to chemical energy.

애플리케이션

A procedure has been described for harvesting native light-harvesting complex IIb (LHCIIb).

This analytical standard can also be used as follows:

• Fourier transform infrared (FTIR) spectroscopy-based quantification of chlorophylls (a & b) and pheophytins (a & b) from five brands of green tea samples
• Development of a high-performance liquid chromatography-diode array detection-mass spectrometric (HPLC-DAD-MS) method for the separation and determination of chlorophylls along with their derivatives in Taraxacum formosanum samples
• Analysis of 14 dietary supplement samples for the quantification of chlorophylls, its degradation products, carotenoids, and pheophytins by a UV-vis spectrophotometric method following their separation by high-performance thin-layer chromatography (HPTLC)
• Evaluation of the effect of pressure, temperature, CO2 flow rate, and a polar co-solvent on the supercritical fluid extraction (SFE) of carotenoids and chlorophylls from microalgae Scenedesmus obliquus for use in food processing
• Simultaneous measurement of chlorophylls (a & b) and carotenoids (β-carotene and lycopene) in fruit samples of strawberry, apricot, and raspberry by two UV-vis spectrophotometric methods
