General description
Chlorophyll b belongs to the class of porphyrins conjugated with magnesium. It absorbs light energy mostly in the blue region and along with chlorophyll a, it is responsible for the green color of plants and green algae.
Application
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

The genuine carotenoid pattern of pineapple infructescence was assessed by HPLC-DAD-APCI-MSn analysis. Prevailing pigments in the shell of 'MD2' (syn. "Extra Sweet") fruit were (all-E)-lutein and (all-E)-β-carotene, in addition to chlorophylls a and b. The edible flesh contained (all-E)-violaxanthin, (all-E)-β-carotene

Chlorophyllase catalyzes the hydrolysis of chlorophyll and produces chlorophyllide and phytol. Cyanobacterial chlorophyllases are likely to be more highly heterologously expressed than plant chlorophyllases. A novel recombinant chlorophyllase from the cyanobacterium Oscillatoria acuminata PCC 6304 was successfully expressed in Escherichia
