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.

Two new tropolone-bearing sesquiterpenoids (1-2), two new dolabrane-type diterpenoids (3-4) along with eight known compounds as ionone-type sesquiterpenoid (5), oleanane triterpenoid (6), vanillin and its derivative (7-8), neolignan (9), two lignans (10-11), flavanonol glycoside (12) were isolated from whole plants of Croton lauioides Radcl.-Sm. & Govaerts.

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).
