“…Carrot is an ordinary vegetable or used as animal food traditionally, not making full use of the carrot from both the nutrition and economy point of view. The consumption of carrots in the long run has many effects in promoting human health such as antioxidant and antiaging effects, development and growth promotion, vision protection, skin health, cancer prevention, chemotherapy side effects reduction, immunity improvement, intestinal micro ecology protection, appetite increasing, and digestion promotion [ 1 – 7 ]. In summary, carrot is a vegetable with rich nutrients and excellent functional ingredients.…”

It was the focus of attention that probiotic control drink was packed with prebiotic nutrients and lactic acid bacteria. So, this study is aimed at revealing that the fermented carrot pulp regulation and protection function to the intestinal microecological disorders usually induced by antibiotic treatment. First, we study on lactobacillus fermentation conditions and effects on the secondary metabolism of fermented carrot juice, get its phenolic acids up, and get its flavonoids down. Then, establishment of the dysbacteriosis mouse model was used to validate the fermented carrot pulp prevention and treatment of intestinal microbiota imbalance. After the antibiotic treatment, the mice showed impotence, laziness, slow movement, weight loss, thin feces, dull hair, and anal redness, while the mice in the control group were all normal in terms of the mental state, diet, weight, and bowl movement. Along with the treatment, the abnormal conditions of the mice in the model group and natural recovery group improved in different degrees, indicating that the fermentation treatment is of help to the intestinal microbiota recovery. The fermentation-treated group of mice recovered close to normal that the diarrhea disappeared, and the weight gain, mental state, and the feces became normal. The serum antioxidant (SOD, GSH, and MDA) levels of the mice were checked. The superoxide dismutase (SOD) levels and glutathione (GSH) levels in the ordinary fermentation-treated group and probiotic fermentation-treated group were significantly increased compare to the natural recovery group. The malondialdehyde (MDA) levels showed great differences between the fermentation-treated groups and the blank group. At last, the 16sRNA analysis revealed that the microbiota richness and diversity in probiotic fermentation (J) are much higher than those in the model group (H), ordinary fermentation group (I), and blank group (G). Groups J and I are of significantly higher antioxidant level than group H; however, only the glutathione (GSH) level in group J increased dramatically but not those in the other three groups. Antibiotic treatment-induced mouse intestinal microecological disorder reduce the microbiota richness and diversity. Prebiotics fermented carrot pulp treatment can help in the recovery from the microbiota richness and diversity level prior to the antibiotic treatment, which suggests it can regulate and protect the murine intestinal microbiome.

“…A calibration graph was built on the absorption of gallic acid solutions. The results were expressed in mg • gallic acid equivalents / L. The total amount of flavonoids in the extracts was determined according to the method proposed by Chang, C.-C. et al [7]. A calibration graph was built on the absorption of quercetin solutions.…”

The aim of this work was to study the content of biologically active compounds in aqueous and ethanol extracts of the roots and rhizomes of elecampane, meadow clover grass and sea buckthorn berries, as well as to determine the indicators of their antioxidant activity. Water extracts were prepared in the form of two dosage forms recommended by the Pharmacopoeia of the Russian Federation -infusion and decoction, differing by the duration of the heat treatment. In the extracts, the amount of antioxidant compounds such as phenolic compounds, flavonoids, carotenoids was estimated, and the content of chlorophylls was also determined in clover extracts. It is shown that 70 vol. % ethanol extracts all detectable compounds more efficiently than water. The largest amount of biologically active substances (except chlorophylls) was extracted from sea buckthorn berries. The restorative power and antiradical activity of the extracts were investigated. It was shown that in the case of each plant separately, ethanol extracts showed a higher reducing power and antiradical activity compared to water. However, when comparing plant extracts with each other, it was found that both ethanol and even water extracts of sea buckthorn berries in these indicators prevailed over ethanol extracts of elecampane and clover.

“…Pigments containing polyene chains are widespread in nature [16]. Carriers include phytoplankton, calcareous skeletons such as some mollusc shells, vegetables such as carrots, bird feathers and even macular pigments of the human retina [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The vast majority of these pigments belong to the carotenoid family.…”

Nature of Pigments in Orange and Purple Coloured Chinese Freshwater Cultured Pearls: Insights from Experimental Raman Spectroscopy and DFT Calculations

et al. 2023

Pearls, a well-known organic gemstone, are popular for their attractive lustre and rich colour. The pigmentation and colour of pearls have never been clearly explained. Understanding the pigments and colour origin of pearls can be a guide for artificial cultivation and rational conservation. In this study, Chinese freshwater cultured pearls were collected as research samples. The appearance and colour characteristics of pearls were characterised using D65 standard light source photography and UV–Vis spectroscopy, the molecular structure of the pigments in the pearls was characterised using Raman spectroscopy, and Density Functional Theory (DFT) calculations were used to reveal the characteristics of the pigments in the pearls in terms of molecular structure and electronic excitation. It was proposed that freshwater pearls are coloured with polyene pigments, with the chain length of the polyene determining the type of colour and the concentration of the polyene determining the colour intensity of the pearl. The HOMO–LUMO transition of conjugated polyenes is intrinsically responsible for the colour of pearls. Many colour-rich biominerals also have similar Raman spectral features to pearls, and this study has wider implications for understanding the nature of pigments and their colour origins.
