A new ionone glycoside, frehmaglutoside I (1), and three new rhemaneolignans A-C (2-4) were isolated from the 95% EtOH extract of the roots of Rehmannia glutinosa. Their structures were determined by extensive spectroscopic (UV, IR, HR-ESI-MS, 1D and 2D NMR) analyses. In addition, these compounds were evaluated for their protective effects on cardiocytes impaired by doxorubicin in H9c2 cells. Among them, compounds 1-3 exhibited protective effects against DOX-induced cardiotoxicity.

February 2025

Instituto de Ciencias de la Vid y del Vino-ICVV (CSIC, UR, GR) Finca La Grajera, 26007 Logroño, La Rioja, Spain. Electronic address:

Glycosides represent a large source of potential flavor in grape must. Commercial preparations enzymes with glycosidase activity are commonly employed to enhance wine aroma. In this study, we conducted an evaluation of twelve commercial enzymes to assess their effectiveness in releasing volatile compounds from their conjugated forms in a white grape must under laboratory conditions by solid-liquid extraction (SPE) and gas chromatography-mass spectrometry (GC-MS).

June 2024

Department of Agriculture and Forest Sciences (DAFNE), Tuscia University, Via S. Camillo de Lellis Snc, 01100 Viterbo, Italy.

Article Synopsis
  • The research focuses on verifying the authenticity of Italian red wine grape varieties, specifically Aglianico, Negroamaro, Primitivo, and Uva di Troia, through the analysis of berry markers.
  • Methods used include measuring compounds such as anthocyanins, hydroxycinnamic acids, shikimic acid, and glycosidic aroma precursors, which help identify varietal characteristics even after aging.
  • Principal Component Analysis was employed to effectively interpret the data and demonstrate that certain compounds can serve as reliable markers for the varietal authenticity of red wines.
