Potatoes (Solanum tuberosum L.) are a good source of dietary antioxidant polyphenols. This study investigated the potential antioxidant, bactericidal, and cytotoxic activities in vitro of the phenolic compounds present in tubers of one S. tuberosum spp. tuberosum (Summerside), and three S. tuberosum spp. andigena (landraces Moradita, Waicha, and Santa María) cultivars. Both the content of phenolic acids, chlorogenic acids (CGAs) being the most abundant, and the antioxidant activity were higher in extracts from skin than from flesh. Extracts from Moradita flesh and Summerside skin showed bactericidal activity against Escherichia coli ATCC 25922 but failed to inhibit pathogenic E. coli O157. Both extracts lack pigmentation but do contain 5-CGA, caffeic, and ferulic acids. Positive control with gentamicin and commercial 5-CGA resulted in a complete inhibition of bacterial growth. In addition, all potato extracts and commercial 5-CGA diminished dose-dependently human neuroblastoma SH-SY5Y cell viability. Skin extracts were more potent than flesh extracts. Among flesh extracts, Moradita was the most potent. Together, our results suggest that Moradita flesh could provide a desirable source of important health-promoting substances. Findings indicate that the biological activity of potato extracts is a combination of various bioactive compounds and contribute to the revalorization of potato as a functional food.

“…γ -токоферол и αтокотриенол обнаруживались в незначительных количествах [12]. При пересчете на сухую массу содержание витамина E находится в диапазоне от 0,8 до 34,8 мкг / г. Существенных различий в содержании α -токоферола у картофеля с красной и белой мякотью выявлено не было [13]. Согласно другим данным, содержание витамина E в испечённом картофеле с красной мякотью было в 2 раза выше, чем в белом, но все равно оставалось крайне низким (0,08 мг/100 г).…”

Антиоксидантная активность пигментированного картофеля (Solanum tuberosum L.), содержание антоцианов, их биосинтез и физиологическая роль РЕЗЮМЕ Актуальность. Сорта картофеля с красной и фиолетовой мякотью представляют высокую диетическую ценность, так как являются источниками полифенольных соединений с антиоксидантной активностью, прежде всего антоцианов. Установлено, что содержание антоцианов у картофеля коррелирует с суммарным содержанием растворимых фенольных соединений и антиоксидантной активностью. Эти показатели значительно выше у картофеля с пигментированной кожурой и мякотью. При холодном хранении такого картофеля содержание фенольных соединений, в частности антоцианов, увеличивается. Пигментированный картофель также является более предпочтительным для потребления в пищу и промышленной переработки, так как в ходе этих процессов сохраняет антиоксидантные свойства и улучшает качество конечных продуктов. Селекция картофеля по признаку окраски мякоти и биотехнологические подходы регуляции накопления антоцианов базируются на понимании молекулярно-генетических процессов их биосинтеза. Биосинтез антоцианов включен в фенилпропаноидный метаболический путь и находится под контролем комплекса MBW, который включает в себя транскрипционные факторы MYB, bHLH и WD40. У картофеля был идентифицирован ряд генов, принадлежащих комплексу MYB. Ключевая роль в изменчивости по признаку пигментации в данный момент отводится гену StAN1. Имеются обширные данные о защитной роли антоцианов в ответ на различные типы стресса у картофеля. Ключевые слова: Solanum tuberosum L., антиокисдантная активность, фенольные соединения, антоцианы, комплекс MBW. Antioxidant activity of potatoes (Solanum tuberosum L.) and anthocyanin content, its biosynthesis and physiological role ABSTRACT Relevance. Potatoes with red and purple flesh are highly valued dietary products and sources of polyphenolic compounds with antioxidant activity, especially anthocyanins. It has been found that the anthocyanin content in potatoes correlates with the total soluble phenolic content and antioxidant activity. These measures are significantly higher for coloured potatoes. The total phenolic content in particular the total anthocyanin content increases during the cold storage of coloured potatoes. Pigmented potatoes are also more preferable for food and industrial processing because of retaining of antioxidant properties and improving of final products quality. Сoloured potatoes selection and biotechnological approaches of regulation of anthocyanins accumulation are based on the understanding of the molecular genetic processes of anthocyanins biosynthesis. The anthocyanin biosynthesis is a part of the phenylpropanoid metabolic pathway. It is controlled by the MBW complex. The MBW complex includes the transcription factors MYB, bHLH, and WD40. A number of the MYB complex genes have been identified in potatoes. The key role in potatoes pigmentation variability is currently assigned to the StAN1 gene. According to available data anthocyanins play a protective role in res...

“…The potatoes/starches possessing potent H-ORAC values were taro (satoimo, 10.10 (7.15-14.83)) and potato (6.61 (5.53-7.72)), and those possessing potent L-ORAC values were sweet potato (1.15 (0.69-1.57)) and potato (0.86 (0.56-1.08)). Potato (26) and sweet potato (27) contain several phenolic antioxidants, predominantly chlorogenic acid. Anthocyanins are found in red or purple colored potatoes as potent antioxidants (28); however, all samples used here were white or yellow potatoes, which are common in Japan.…”

To provide reliable data for high quality epidemiological studies examining the relationship between health and antioxidant intake from daily foods, 107 plant-derived food items (12 rice, bread and noodles, 5 potatoes and starches, 9 pulses, 6 nuts/seeds, 29 vegetables, 22 fruits, 5 mushrooms, 7 algae, and 12 beverages) were selected as commonly consumed foods in Japan based on dietary records, and their antioxidant capacities were evaluated by validated hydrophilic-and lipophilic-oxygen radical absorbance capacity (H-ORAC and L-ORAC) methods. The food items covered more than 60% of total food intake for each category on a weight basis. The H-ORAC and L-ORAC values were widely distributed at 0-210 and 0-30 mmol-Trolox equivalent/g, respectively. The foods possessing potent antioxidant capacities were found in vegetables and fruits as well as other plant-derived foods. In most foods measured, the H-ORAC values were much larger than the L-ORAC values, except for certain kinds of pulses, nuts/seeds, mushrooms, and algae. The ORAC data shown here is sufficient to accurately estimate the antioxidant intake from plant-derived foods in Japan, and should be useful in future epidemiological studies aiming to clarify the biological significance of ORAC values.
