“…Valfi was 2.46 to 3.18-fold higher than in cultivars with yellowcolored flesh. Kröner et al (2012) and Brazinskiene et al (2014) did notobserve significant correlations between the phenolic acid content of potato tubers and the spread of P. infestans. According to the cited authors, the incidence of disease is more likely to be influenced by the production system than the phenolic acid content of tubers.…”

In this study, the influence of potato cultivars Irga, Satina, Valfi, Blaue St. Galler and Highland Burgundy Red (HB Red), growth regulators: Bio-Algeen S-90, Kelpak SL and Trifender WP, and the biostimulator Asahi SL on the health status of potato plants and tuber yield was investigated. The severity of late blight and early blight was estimated during the growing season. After harvest, potato tuber yield was determined according to size fractions. The applied treatments significantly reduced the severity of late blight in cv. Irga (Kelpak SL), Valfi (Bio-Algeen S-90, Kelpak SL, Trifender WP) and Blaue St. Galler (Trifender WP) in 2013. In 2015, the symptoms of early blight were significantly reduced in cv. Irga after the application of all tested bioregulators. HB Red was characterized by the best health status among the evaluated cultivars. Kelpak SL and BioAlgeen S-90 increased the tuber yield of cvs. Irga and HB Red, respectively, in 2013, and Trifender WP increased the tuber yield of cv. Satina in 2014. In the first year of the study, the applied growth regulators and biostimulator significantly increased the percentage of medium-sized tubers of cv. Blaue St. Galler, and Bio-Algeen S-90 increased the percentage of medium-sized tubers of cv. HB Red.

“…However, in the study by Kröner et al . (), the highest level of rutin was found in tubers from the cultivar with the highest resistance to Pectobacterium atrosepticum . This further emphasizes the apparently versatile roles of individual phenolics in different plant–pathogen interactions (Treutter, ), and underlines the importance of detailed studies on interaction‐specific responses in understanding how induced plant responses can be used in plant protection.…”

“…The flavonoid rutin was one of the phenols present in more pronounced concentrations in Bintje than in Ovatio and is therefore less likely to be involved in BABA‐IR to P. infestans . This is supported by two recent studies (Henriquez et al ., ; Kröner et al ., ) showing that rutin occurred at higher concentrations in a potato cultivar more susceptible to P . infestans .…”

Late blight caused by Phytophthora infestans is one of the most devastating diseases of the potato crop. Resistance breeding and current fungicides are unable to control the rapidly evolving P. infestans and new control strategies are urgently needed. This study examined mechanisms of DL-b-aminobutyric acid (BABA)-induced resistance (IR) in the potato-P. infestans system. Leaves from two cultivars that differ in their degree of resistance, Bintje and Ovatio, were analysed after foliar treatment with BABA. Rapid activation of various defence responses and a significant reduction in P. infestans growth were observed in leaves treated with BABA. In the more resistant cultivar, Ovatio, the activation was both faster and stronger than in Bintje. Microscopic analysis of leaves treated with BABA revealed induction of small hypersensitive response (HR)-like lesions surrounded by callose, as well as production of hydrogen peroxide (H 2 O 2 ). Molecular and chemical analyses revealed soluble phenols such as arbutin and chlorogenic acid and activation of PR-1. These results show a direct activation of defence responses in potato, rather than priming as reported for other plant species. They also show that the efficiency of BABA-IR differs between cultivars, which highlights the importance of taking all aspects into consideration when establishing new methods for disease management.

“…Moreover, the ion m/z 151.0031 originating from the RDA reaction was also found. Therefore, peaks 20 and 21 were identified as nicotiflorin and rutin by comparison of their retention behavior and MS/MS spectrum with the literature data (Kröner et al ., ). Similarly, peaks 42 and 43 were identified as capillarisin and 6‐demethoxyl‐4′‐methyl‐capillarisin (Lv et al ., ; Wang et al ., ).…”

HPLC‐Q‐TOF‐MS/MS for analysis of major chemical constituents of Yinchen–Zhizi herb pair extract

The Yinchen-Zhizi herb pair (YZHP) consists of Herba Artemisiae Scopariae (Yinchen in Chinese) and Fructus Gardeniae (Zhizi in Chinese), and is mainly used to treat icteric hepatitis, itching skin and eczema. However, the bioactive constituents responsible for the pharmacological effects of YZHP are still unclear to date. In this work, a rapid and sensitive method was established to comprehensively study the constituents in YZHP extract by HPLC-Q-TOF MS/MS. The analysis was performed on an HPLC system equipped with an Agilent poroshell 120 EC-C18 column (100 × 2.1 mm, 2.7 mm) working in a gradient elution program coupled to quadrupole-time-of-flight mass spectrometry operating in the negative ion mode. As a result, a total of 46 compounds including 17 from Herba Artemisiae Scopariae and 36 from Fructus Gardeniae were detected and tentatively identified in YZHP extract by comparing the retention time and mass spectrometry and retrieving the reference literature. More importantly, a series of constituents, such as many iridoid glycosides, were reported for the first time in this formula. The HPLC-Q-TOF MS/MS method was developed and utilized successfully to identify the major constituents in YZHP extract and would be helpful for further metabolism and pharmacology research on YZHP.
