“…The extraction process for FPCS was optimized as an improvement on the traditional solvent extraction method reported previously [ 28 ]. Response surface methodology (RSM) is commonly used to optimize complex extraction procedures as it can simultaneously evaluate the effects of different parameters, as well as their interactions [ 5 , 29 , 30 ].…”

In this work, the extraction procedure of a natural pigment from the flower of Ceiba speciosa (A. St.-Hil.) was optimized by response surface methodology. It is the first time that the extraction of the flower pigment of C. speciosa (FPCS) has been reported, along with an evaluation of its stability and biological activity under various conditions, and an exploration of its potential use as a food additive and in medicine. Specifically, the effects of ethanol concentration, solid–liquid ratio, temperature and time on the extraction rate of FPCS were determined using a Box–Behnken design. The optimum extraction conditions for FPCS were 75% ethanol with a solid–liquid ratio of 1:75 mg/mL) at 66 °C for 39 min. The purification of FPCS using different macroporous resins showed that D101 performed best when the initial mass concentration of the injection solution was 1.50 mg/mL, resulting in a three-fold increase in color value. The yield of dry flowers was 9.75% of fresh petals and the FPCS extraction efficiency was 43.2%. The effects of light, solubility, pH, temperature, sweeteners, edible acids, redox agents, preservatives and metal ions on FPCS were also investigated. Furthermore, the characteristics of FPCS were determined by spectrophotometry at a specific wavelength using the Lambert–Beer law to correlate the mass of FPCS with its absorbance value. An acute toxicological test performed according to Horne’s method showed that FPCS is a non-toxic extract and thus may be used as a food additive or in other ingestible forms. Finally, western blotting showed that FPCS prevents lipopolysaccharide-induced hippocampal oxidative stress in mice. The study suggests that FPCS may function as an antioxidant with applications in the food, cosmetics and polymer industries.

Background: Breast cancer is the most lethal cancer causing death among women, especially in developed countries. Using medicinal plants and natural resources to control and prevent different types of cancer in human has been the focus of attention. Objectives: The current study aimed to investigate the possible effects of hydroalcoholic extracts from some plant species such as Lavandula angustifolia, Ephedra major, and Scenedesmus obliquus on cell viability of two breast cancer MCF7 and SK-BR3 cell lines. Methods: MTT assay and gene expression analysis were performed adopting qRT-PCR method. Target cells were treated with different concentrations of plant extracts in a 24-hour period. Data were analyzed using Graphpad Prism version 8.3.0. Differences among means were determined using Student’s t-test or one-way ANOVA with Dunnett’s Multiple Comparison Test. Results: An indirect relationship was detected between extract concentration and cell viability. The result of the cell viability (IC-50) showed that the extract of S. obliquus had the maximum effect on both tested cells at concentrations above 100 µg/mL. A high cell death rate was observed in MCF-7 cell line compared to SK-BR3 cell line 24 h after the treatment. According to results from gene expression analysis, Caspase 3 gene increased in all treated cells, while the bcl-xl gene expression declined in the tested cells. Conclusions: It was concluded that the extracts from three plants had both positive and dose-related effects on MCF-7 and SK-BR3 cell line. However, it was recommended that future complementary studies should be conducted in order to evaluate the cell viability effect of these plants on human cancer.

“…It is produced by adding β -glucosidase to a mixture of cyclic enzyme glycosides extracted from gardenia fruit to produce kynepin [21] Although kynepin itself has no color, it can react with protein hydrolysis products to produce a blue substance, providing a new natural dye for the textile, cosmetic, and food industries. [9,22] . In addition to this, the preparation of natural blue pigments using metabolites produced by microbial cultures is now a major research target [23][24][25] .…”

“…Natural blue pigments are susceptible to structural degradation and changes when subjected to external factors such as light, temperature and pH [9] , so it becomes essential to study the extraction conditions of the pigments. It was found that the methods of extraction of biological compounds from microalgae include supercritical fluid extraction [38] microwave-assisted extraction [39] extraction, pressurized liquid extraction [40] ultrasonic assisted extraction [41] and pulsed electric field treatment.…”

“…Japan is the most advanced country in the world in terms of research into the use of natural food coloring, as a representative of the more stringent requirements for product quality and environmental efforts [8] Japan is the most advanced country in the world in terms of research into the use of natural food coloring, followed by the United States, where large amounts of natural red and natural yellow pigments have been identified in past research. [9] . The coloring effect of natural pigments is closer to the original color of the substance, with the improvement of the level of science and technology, China has also conducted a lot of research and exploration of natural food coloring, to a certain extent to expand the range of varieties of pigments available, according to statistics have been up to more than forty typical pigment varieties, common pigments such as curcumin, red currant red, tea yellow pigment, etc.…”

Natural edible blue pigment is a scarce pigment among natural pigments, mainly derived from animal and plant tissues, microbial fermentation metabolites. Among the plant natural blue pigments, the ones that account for the widest market of edible natural blue pigments are algal blue pigment and gardenia blue pigment. The sources of microbial natural blue pigment include some fungi and bacteria in addition to microalgae, mainly focusing on the study of Streptomyces, Pseudomonas, Pseudoalteromonas, purple non-sulfur bacteria, Dourollerella, and sprouting short-stalked mold. The natural blue pigment is unstable, so it is of far-reaching significance to improve the extraction process, especially the research on the isolation and purification of blue pigment produced by microbial fermentation. High-speed frozen centrifugation, solid-phase extraction, high performance liquid chromatography, nuclear magnetic resonance spectroscopy, mass spectrometry and other methods are commonly used for the separation and purification of natural blue pigments and analytical identification. Some natural blue pigments have antioxidant, antitumor, hypolipidemic, hypoglycemic, anti-inflammatory, anti-cancer, immunomodulatory activities, etc. There will be a broad development prospect for the future research of natural blue pigments.
