“…They are also well known for inducing an antifungal activity [13][14][15][16][17][18] and, for example, we observed by MSI experiment a co-localization of resveratrol and pterostilbene (trimethoxystilbene) at the infection site on the leaf abaxial side (Cabernet Sauvignon) [12] after infection by downy mildew. MSI allowed the identification and mapping of resveratrol and pterostilbene but the biosynthesis of some other stilbenes is also expected to be induced in grapevine leaves and even berries in response to pathogen infection or UV irradiation [19][20][21]. Besides the glycosylation of stilbenes (e.g., piceids), oxidative oligomerization of resveratrol catalyzed by plant peroxidases may occur and several of them have been identified in stressed grapevine leaves [22][23][24].…”

MALDI Mass Spectrometry Imaging for the Simultaneous Location of Resveratrol, Pterostilbene and Viniferins on Grapevine Leaves

Abstract:To investigate the in-situ response to a stress, grapevine leaves have been subjected to mass spectrometry imaging (MSI) experiments. The Matrix Assisted Laser Desorption/Ionisation (MALDI) approach using different matrices has been evaluated. Among all the tested matrices, the 2,5-dihydroxybenzoic acid (DHB) was found to be the most efficient matrix allowing a broader range of detected stilbene phytoalexins. Resveratrol, but also more toxic compounds against fungi such as pterostilbene and viniferins, were identified and mapped. Their spatial distributions on grapevine leaves irradiated by UV show their specific colocation around the veins. Moreover, MALDI MSI reveals that resveratrol (and piceids) and viniferins are not specifically located on the same area when leaves are infected by Plasmopara viticola. Results obtained by MALDI mass spectrometry imaging demonstrate that this technique would be essential to improve the level of knowledge concerning the role of the stilbene phytoalexins involved in a stress event.

“…Postharvest treatment with UV-C light has been proposed as a valuable method to increase the stilbenes content in the grape berries (Langcake and Pryce 1977;Douillet-Breuil et al 1999;Versari et al 2001;Petit et al 2009;Yin et al 2016). Postharvest treatment of grape varieties with UV-C resulted in higher concentrations of stilbenes, such as E-resveratrol, piceatannol, viniferins and pterostilbene (Table 2, no.…”

The stilbene profile in edible berries

2018

View full text Add to dashboard Cite

Edible berries are becoming increasingly popular to consume in fresh, dried, frozen or processed forms due to their high content and wide diversity of bioactive compounds with considerable health benefits. Among the wide variety of phytochemicals found in berries are stilbenes, which demonstrate a broad range of biological and pharmacological activities. Their content depends on many factors, including the cultivar, ripening stage, climatic conditions, agronomic management, storage conditions and postharvest management. However, the application of various abiotic and biotic external stimuli could be a strategy for increasing the production of stilbenes in edible berries. To date, several different elicitors, as inducers of plant secondary metabolite stilbenes, have been applied in different studies. This review focuses on the isolation and identification of stilbenes from edible berries and presents the influence of different external stimuli on their profile in grapes.

“…Its production occurs in vine plants as response to fungic infections and other kind of stresses (UV radiation, chemicals, climatic conditions, etc.) [17][18][19][20]. This compound has shown to be fungitoxic at physiological concentrations against Botrytis cinerea [21], which is the most destructive of the post-harvest diseases of table grapes.…”

This work demonstrates that the own plant defence compounds, like resveratrol in grapes, can be used as a natural and ecological alternative to chemical pesticides. An extract from vine leaves was used to maintain the quality of post-harvested grapes. Specifically, an extract (95% water and 5% ethanol) of such leaves was prepared and, subsequently, different bunches of grapes were immersed in it. The same number of bunches received either water or ethanol (5%) treatment, being both used as blank. Remarkably, on the 14th day after the beginning of the treatment the extract treated grapes, always maintained at room temperature, showed no sign of physical deterioration. In contrast, the two blank samples, i.e.: the water or ethanol treated bunches appeared dehydrated, infected and deteriorated. Furthermore, the external application of the leaf's extract does not modify sensorial, biochemical and nutritional properties of the fruits. The beneficial effects of trans-resveratrol, such as anticancer, antiviral, neuroprotective, antiaging and anti-inflamatory support further the use of this natural compound instead of hazardous synthetic pesticides. Therefore, this study represents a step towards the development of new protocols to maintain the post-harvest fruit quality without resorting to chemical pesticides.
