Lycopene is the natural coloring compound of the carotenoids that occur in plants and it is significant plant pigment not only due to its color but also it is well known for its health benefits. Many researchers confirmed by in vitro, in vivo, and ex vivo studies that lycopene-enriched ...
Though it has green foliage, it changes to a beautiful shade of red if you’re going to keep it in a small pot and provide full sun. It produces red pigment on the foliage to protect from sunburn. Readers must note that pencil cactus sap istoxic! Growing Tips: Keep the plant on a ...
The major red pigment was identified as gomphrenin I. Its quantity increased with the increase of fruit maturity. The gomphrenin I extract yield from ripe fruits was 36.1 mg/100 g of fresh weight. In addition to gomphrenin I, betanidin-dihexose and isobetanidin-dihexose were also detected...

Spectral reflectance indices and pigment functions during leaf ontogenesis in six subtropical landscape plants Pigment combinations are regulated during leaf ontogenesis. To better understand pigment function, alterations in chlorophyll, carotenoid and anthocyanin c... N Liu - 《Plant Growth Regulation》 被...
The structures reveal several unidentified and incomplete proteins and their roles in the assembly of the megacomplex, as well as a huge and sophisticated pigment network. This work provides a solid structural basis for unravelling the mechanisms of PBS–PSII–PSI–LHC megacomplex assembly, efficient...
The extraction of date-red pigment and its stability were studied. The results showed that the pigment was water soluble, and it was stabal to heat and light. It was also stabal in solutions of hydrochloric acid, sodium hydroxide, metal ions, oxidizers and sucrose, etc; However, it was ...
Relationships between leaf pigment content and spectral reflectance across a wide range of species, leaf structures and developmental stages We also found that an index based on the first derivative of reflectance in the red edge region was insensitive to leaf structural variation. The ... DA Sims...
