Abstract
Could natural plant pigment (chlorophyll) derivatives (chlorophyllins) improve the
safety of the antiviral Molnupiravir, used to treat COVID-19 disease?
Molnupiravir, a specific SARS-CoV-2 antiviral, may cause adverse genetic changes and
thereby create potential host cell damage (through genotoxicity and DNA stressors). In our
opinion, this side effect of treatment could be reduced if the antiviral was taken as a
combined therapy with chlorophyllins. Specifically, we hypothesise that chlorophyllins
might improve the overall effectiveness of molnupiravir, typically used to treat patients
suffering from COVID-19. Chlorophyllins, antioxidants derived from natural plant
chlorophyll, are safe, effective and non-toxic antioxidants that could combat possible
genotoxic flow-on effects of molnupiravir. In addition, as they possess antiviral
properties, treatment with chlorophyllins may enhance the overall antiviral effect via a
mechanism different to molnupiravir.

Abstract
The current increased industrial food production has led to a significant rise in the amount of food waste generated. These food wastes, especially fruit and vegetable byproducts, are good sources of natural pigments, such as anthocyanins, betalains, carotenoids, and chlorophylls, with both coloring and health-related properties. Therefore, recovery of natural pigments from food wastes is important for both economic and environmental reasons. Conventional methods that are used to extract natural pigments from food wastes are time-consuming, expensive, and unsustainable. In addition, natural pigments are sensitive to high temperatures and prolonged processing times that are applied during conventional treatments. In this sense, the present review provides an elucidation of the latest research on the extraction of pigments from the agri-food industry and how their consumption may improve human health.

Shengxuening Extracted from Silkworm Excrement Mitigates Myelosuppression via SCF-Mediated JAK2/STAT3 Signaling. Chem Biodivers 2021; 18:e2100139.

Abstract
Shengxuening (SXN) is a Chinese patent medicine with main ingredients (including chlorophyll derivatives and sodium iron chlorophyllin) extracted from silkworm excrement. SXN exhibited efficacy in clinical trials of renal anemia and iron deficiency anemia; however, the specific mechanisms remain unclear. This study found that SXN increased the number of peripheral blood cells and improved the bone marrow morphology in myelosuppressed mouse model, reversed the reduction in body weight and spleen indices, and increased the serum levels of erythropoietin and granulocyte-macrophage colony-stimulating factor. Quantitative real-time PCR array and Western blot analysis showed the enhanced expression of stem cell factor (SCF), JAK2, and STAT3 in the liver. These results suggested that SXN promoted the recovery of hemopoietic function in myelosuppressed models by increasing the secretion of hematopoietic factors and activating the JAK2/STAT3 pathway. Therefore, this medicine may be applied as therapeutic pharmaceutical drug to mitigate myelosuppression.

Abstract
Precisely tuning the emission wavelength of dual ligands co-functionalized gold nanoclusters (AuNCs) presents a bright prospect for highly selective drug detection. In this study, gold nanoclusters (AuNCs) with strong red fluorescence at 633 nm were synthesized using bovine serum albumin (BSA) and bromelain (Bro) as dual ligands for highly selective detection of sodium copper chlorophyllin (SCC). Interestingly, the auto-fluorescence interference of the dual ligands was effectively avoided due to the fluorescence emission red-shifts of the prepared BSA/Bro@AuNCs; this may be mainly due to the rigid structure of the proteins. The fluorescence of BSA/Bro@AuNCs was quenched after addition of SCC, which performed well and provided a good linear calibration curve in the 5.0-25.0 μM range (R2 = 0.999), and a detection limit as low as 0.5 μM. The proposed assay was further applied to the measurement of SCC in rat serums after an intravenous injection. The dual protein ligand-capped AuNCs showed great potential for drug analysis in actual biological samples.

Abstract
In this study, potential protection of chlorophyll a from illumination and oxidation-induced decomposition has been examined using C-phycocyanin (C-PC) aqueous medium. Photo-oxidation resistance of chlorophyll a was monitored in various aqueous media using ultraviolet-visible spectroscopy and direct-infusion atmospheric pressure chemical ionization mass spectrometry analysis. The spectroscopy results showed that chlorophyll a in C-PC medium experienced the lowest rate of conversion to its derivatives; thus, it was demonstrated that chlorophyll a was mostly intact in the C-PC medium. Furthermore, the C-PC treated with chlorophyll a showed the lowest concentrations of malondialdehyde, and chlorophyll a in C-PC medium did not cause serious damage to human liver cells in vitro after intensive illumination. Therefore, we propose a new method of protecting chlorophyll a from photodegradation and oxidation using C-PC aqueous medium.

Abstract
Chlorophylls and carotenoids are natural pigments that are present in our daily diet, especially with the increasing tendency towards more natural and healthy behaviors among consumers. As disturbed antioxidant homeostasis capacities seem to be implicated in the progress of different pathologies, the antioxidant properties of both groups of lipophilic compounds have been studied. The objective of this review was to analyze the state-of-the-art advances in this field. We conducted a systematic bibliographic search (Web of Science™ and Scopus®), followed by a comprehensive and critical description of the results, with special emphasis on highly cited and more recently published research. In addition to an evaluative description of the methodologies, this review discussed different approaches used to obtain a physiological perspective, from in vitro studies to in vivo assays using oxidative biomarkers. From a chemical viewpoint, many studies have demonstrated how a pigment's structure influences its antioxidant response and the underlying mechanisms. The major outcome is that this knowledge is essential for interpreting new data in a metabolic networks context in the search for more direct applications to health. A promising era is coming where the term "antioxidant" is understood in terms of its broadest significance.

Abstract
A flash extraction method was used to isolate Elaeagnus mollis oil (EMO). The optimal extraction parameters, sample/solvent ratio and extraction temperature, were determined to be 1:10 (g/mL) and 40°C, respectively. Especially, the extraction yield reached 49.30% when the extraction time was as short as 2 min. No obvious difference was observed in fatty acid composition, iodine value, saponification number, total phenolic content and tocopherol content between flash-extracted EMO and Soxhlet-extracted EMO, but their physicochemical values were lower than those of cold-pressed EMO. Cold-pressed EMO had higher oxidation stability, DPPH (1-diphenyl-2-picrylhydrazyl) and hydroxyl radical-scavenging activities than flash-extracted EMO and Soxlet extracted EMO. The flash extraction is demonstrated to be an alternative, efficient method for the vegetable oil production.
