“…Evidence suggests that the accumulation of flavonoids depends on light quality and quantity, which can be a decisive factor for future applications, for example, in medicinal plants to achieve high levels of therapeutic metabolites or in commercial cultivars for improving their nutritional values (Idris et al 2018; Sethi et al 2018). Moreover, flavonoid biosynthesis is also induced by high photosynthetically active radiation (PAR) irradiance to cope with this stressful environmental condition by acting as ROS scavengers in photoprotection (Agati et al 2009, 2011; Kolb et al 2001).…”

Flavonoids are plant specialized metabolites that consist of one oxygenated and two aromatic rings. Different flavonoids are grouped according to the oxidation degree of the carbon rings; they can later be modified by glycosylations, hydroxylations, acylations, methylations, or prenylations. These modifications generate a wide collection of different molecules which have various functions in plants. All flavonoids absorb in the UV wavelengths, they mostly accumulate in the epidermis of plant cells and their biosynthesis is generally activated after UV exposure. Therefore, they have been assumed to protect plants against exposure to radiation in this range. Some flavonoids also absorb in other wavelengths, for example anthocyanins, which absorb light in the visible part of the solar spectrum. Besides, some flavonoids show antioxidant properties, that is, they act as scavengers of reactive oxygen species that could be produced after high fluence UV exposure. However, to date most reports were based on in vitro studies, and there is very little in vivo evidence of how their roles are carried out. In this review we first summarize the biosynthetic pathway of flavonoids and their characteristics, and we describe recent advances on the investigation of the role of three of the most abundant flavonoids: flavonols, flavones, and anthocyanins, protecting plants against UV exposure and high light exposure. We also present examples of how using UV-B supplementation to increase flavonoid content, is possible to improve plant nutritional and pharmaceutical values.

“…53 Similarly, an increase in light intensity resulted in the increase of flavonoids in plants. 54 Whereas we did not measure UV radiation in this study, we expect it to be higher on the green roof due to reflectance from the building. So, we expect UV radiation to play a role, but soil type and other environmental factors such as temperature, water, and soil fertility may also influence secondary metabolites in plants.…”

The phytochemical composition in the leaves of seven accessions of Hibiscus sabdariffa L. grown under field, green roof, and high tunnel conditions was investigated in the present study. Principle component analysis of freeze-dried leaves using near-infrared (NIR) spectral fingerprinting revealed differences between accessions and the three growing conditions. Under all conditions, NIR fingerprint data of accession PI 286316 showed variation from the other six accessions (PI 256041, PI 267778, PI 273388, PI 275414, Thai red, and UDC green). A detailed investigation of the phytochemical composition of the accessions by high-performance liquid chromatography coupled with diode array and high-resolution mass spectrometry showed the presence of 16 bioactive phenolics. In six accessions, ten phenolics were identified as compared to eight phenolics in accession 286316, six of which from the latter were unique and not previously reported in H. sabdariffa leaves. Only two phenolics, namely neochlorogenic acid and chlorogenic acid, were common in all seven accessions. Total phenolics in samples from the green roof were 12% and 16% higher than those from the field and high tunnel, respectively. Ten free soluble amino acids and three soluble sugars were identified in all accessions. However, total amino acids and sugars in leaves from the field were between 24 and 42% higher than leaves from the green roof and high tunnel. This study shows that H. sabdariffa leaves provide a good source for bioactive phenolics, free amino acids, and sugars, hence, it can be a nutritious addition to meals.

Cadmium nanoparticles (NPs) used in semiconducting devices are photosensitive and optically active. The objective of this study was to investigate the interactive effect of different spectral lights and CdO NPs on morphological, antioxidant, and phytochemical characteristics of Dodonaea viscosa . The plants were grown on media in the presence of green and chemically synthesized CdO NPs and under red, yellow, green, blue, and white light intensities. Results illustrated that plant morphological parameters changed in the presence of different spectral lights and NPs behaved differentially under different spectral lights. Fresh and dry weights of plants decreased in the presence of NPs in the media; however, the concentration and route of synthesis of NPs have a significant effect on these parameters. The same was observed in the case of shoot and root lengths; however, green synthesized NPs were found to be less toxic under different spectral lights. The total antixodant response increased under yellow, blue, and white lights, while the total reducing potential of plant extracts significantly varied depending upon the NP concentration and light spectrum. Different spectral lights significantly influenced the syntheses of phenolics and flavonoids under CdO NP stress and light regimes. It is concluded that toxicity of NPs also depends upon the wavelength of striking light that varies the morphological, biochemical, and antioxidative response of the plants. Furthermore, the white light might have synergistic effects of different wavelengths.
