“…This approach was also confirmed by Pearson correlation analysis and we observed a strong correlation between total phenolic content and results of antioxidant assays (Figure 3). In consistency with our results, some authors reported a linear correlation between the total phenolic level and antioxidant properties (Cortés‐Estrada et al., 2020). Also, the antioxidant properties of V. album extracts were attributed to the presence of phenolic compounds in earlier studies (Tahirovic & Basic, 2017).…”

Viscum album L. (Mistletoe) is one of the most famous plants in many countries utilized for several purposes. The current study aimed to describe chemical profiles and biological activities of homogenizer‐assisted extract (HAE) and ultrasound‐assisted extract (UAE)) of V. album parts (leaf, fruits, and seeds). Antioxidant (radical scavenging, reducing power, metal chelation, and phosphomolybdenum assays) and enzyme inhibitory properties (cholinesterases, amylase, glucosidase, and tyrosinase) were selected for biological evaluation. Chemical profiles were studied by HPLC‐MS/MS and 32 compounds were identified in the extracts; caffeoylquinic acids and its derivatives, dimethylated flavonoids were the most significant compounds. Generally, the leaf extracts exhibited the best antioxidant and enzyme inhibitory effects in our tests. Multivariate analysis was performed to obtain more information for these data, then strong correlations between total bioactive compounds and tested parameters were observed. The present findings encourage us to further investigate V. album as a potential candidate for pharmaceutical and nutraceutical applications. Practical applications Viscum album L. commonly called European mistletoe is a woody perennial shrub growing on coniferous trees with lathery leaves, small flowers, and white berries. It belongs to the Santalaceae R. Br. family from Europe and western/southern Asia. Traditional medicine recognizes mistletoe as a folk remedy to manage inflammation, hypertension, ulcers, and other diseases due to the presence of different bioactive compounds, among them mistletoe lectins and viscotoxins. Recent studies documented the possible therapeutic applications of Viscum extracts in association with cancer's therapy leading to improvements in health and patient's quality of life. Thus, this work gives novel data regarding the phytochemical characterizations and antioxidant/enzymatic inhibitor activities of different types of extracts from seeds, leaves, and fruits of Viscum L. obtained by homogenizer‐assisted and ultrasound‐assisted techniques, in order to increase the data set of potential applications in medicine.

“…They showed that the antioxidant activity of bell pepper fruits increased with the elicitor agents (jasmonic acid, hydrogen peroxide, and chitosan) during postharvest. In addition, the bell pepper juice from green, yellow, orange, and red fruits exhibited antioxidant activity using the DPPH and ABTS methods, which could make it a viable option for bell pepper consumption [ 60 ].…”

Bell Peppers (Capsicum annum L.) Losses and Wastes: Source for Food and Pharmaceutical Applications

et al. 2021

Currently, the high added-value compounds contained in plant by-products and wastes offer a wide spectrum of opportunities for their reuse and valorization, contributing to the circular economy. The bell pepper (Capsicum annum L.) is an exotic vegetable with high nutritional value that, after processing, leaves wastes (peel, seeds, and leaves) that represent desirable raw material for obtaining phytochemical compounds. This review summarizes and discusses the relevant information on the phytochemical profile of bell peppers and their related biological properties as an alternative to revalorize losses and wastes from bell peppers for their application in the food and pharmaceutical industries. Bell pepper fruits, seeds, and leaves contain bioactive compounds (phenols, flavonoids, carotenoids, tocopherol, and pectic polysaccharides) that exhibit antioxidant, antibacterial, antifungal, immunosuppressive and immunostimulant properties, and antidiabetic, antitumoral and neuroprotective activities, and have a potential use as functional food additives. In this context, the revalorization of food waste is positioned as a technological and innovative research area with beneficial effects for the population, the economy, and the environment. Further studies are required to guarantee the safety use of these compounds and to understand their mechanisms of action.

“…Despite the differences between the two approaches, it is evident from the Figure that they are consistent in terms of the spectral bands identified as relevant for the discrimination between pure and adulterated Senise samples. In fact, as far as the MIR block is concerned, VIP analysis identifies as relevant the intervals of 955-1223 cm −1 and 2844-2960cm −1 , while, in the same spectral ranges, SO-CovSel-LDA selects two variables, the peak at 1024 cm −1 and the one at 2924cm −1 , attributable to the C-O-C, C-C and C-O stretching in organic acids and carbohydrates and to the (a) symmetric stretching of CH2 and CH3 [33], respectively. The other relevant spectral intervals selected based on the values of the VIP scores are those between 3171 cm −1 and 3429 cm −1 ascribable to the O-H stretching, and between 1691 cm −1 and 1757 cm −1 , probably related to the absorption of the C=O, C=C and the O-H vibrations in phenolic compounds, carotenes and organic acids [33].…”

Sequential Data Fusion Techniques for the Authentication of the P.G.I. Senise (“Crusco”) Bell Pepper

Bell pepper is the common name of the berry obtained from some varieties of the Capsicum annuum species. This agro-food is appreciated all over the world and represents one of the key ingredients of several traditional dishes. It is used as a fresh product, or dried and ground as a seasoning (e.g., paprika). Specific varieties of sweet pepper present organoleptic peculiarities and they have been awarded by quality marks as a further confirmation of their unicity (e.g., Piment d’Espelette, Pimiento de Herbón, Peperone di Senise). Due to the market value of this aliment, it can be subjected to frauds, such as adulterations and sophistication. The present study lays on these considerations and aims at developing a spectroscopy-based approach for authenticating Senise bell pepper and for detecting its adulteration with common paprika. In order to achieve this goal, 60 pure samples of bell pepper from Senise were analyzed by mid- and near-infrared spectroscopies. Then, in order to mimic the adulteration, 40 mixtures of Senise bell pepper and paprika were prepared and analyzed (by the same spectroscopic techniques). Eventually, two different multi-block classification approaches (sequential and orthogonalized partial least squares linear discriminant analysis and sequential and orthogonalized covariance selection linear discriminant analysis) were used to discriminate between pure and adulterated Senise bell pepper samples. Both proposed procedures achieved extremely successful results in external validation, correctly classifying all the (thirty-five) test samples, indicating that both approaches represent a winning solution for the investigated classification problem.
