dc.description.abstractBotrytis bunch rot, caused by Botrytis cinerea, is an important disease of grapevines in temperate climates worldwide. It can cause extensive economic losses through grape desiccation, rot, and biochemical changes that reduce wine quality. Therefore, it is crucial to identify new compounds, especially natural ones, that are active against B. cinerea. Biofungi cides from plant origin have been recommended to reduce viticulture’s dependence upon synthetic fungicides for the last decades [1]. Cistus (Cistus ladanifer L.) is a perennial shrub from the Cistaceae family that can be found in abundance in the Mediterranean's marginal fields [2]. Moreover, cistus phenolic extract has been described as a potential antifungal agent, due to its interesting phenolic composition, including ellagitannins and flavonoids [3]. In this sense, the present study evaluated the antifungal potential of a phenolic extract of C. ladanifer from Northeastern Portugal, against B. cinerea. Dry leaves from cistus were extracted by maceration using ethanol: water (80:20 v/v) as solvent. The phenolic extracts were characterized by HPLC-DAD/ESI-MS and evaluated for their capacity to inhibit B. cinerea using the microdilution method. Ellagic acid derivatives (24.3 mg/g extract; 83.8%), flavonoids (3.93 mg/g extract; 13.6%), such as flavonols and flavones; phenolic acids, and derivatives (0.76 mg/g extract; 2.6%), were found in the sample (Figure 1). The most abundant group was ellagic acid derivatives in which punicalagin and punicalagin gallate, were found in the highest amounts (13.3±0.9 and 11±2 mg/g extract, respectively), being these results in line with previous studies [3]. The extract revealed an interesting capacity to inhibit the growth of B. cinerea at a concentration of 10 mg/mL, which could be related with the high composition in ellagitannins. Considering the bioactivity of cistus phenolic extract, this natural product could be applied as an alternative to synthetic fungicides used in the prevention and treatment of fungal infections in grapevine, minimizing the environmental and health impacts caused by these chemical agents.eng
