Article Synopsis
- Five new labdane diterpenoids (Stevelins A-E) and three known labdane diterpenoids were identified from the plant Stevia rebaudiana.
- The structures of these compounds were determined using NMR spectroscopy, high-resolution mass spectrometry, and X-ray crystallography, with additional insights from electronic circular dichroism calculations.
- Most of the isolated compounds showed significant effects in inhibiting foam cell formation induced by oxidized low-density lipoprotein, indicating their potential as treatments for atherosclerosis.
