neo-Clerodane diterpenoids from the leaf exudate of Dodonaea angustifolia

Differential Deterrent Activity of Natural Products Isolated from <i>Allophylus edulis</i> (Sapindaceae)

“…The signals observed in the mass spectra, 1 H and 13 C NMR revealed that 6 is 2-oxo 13-hidroxy-neo-cleroda-3,14-diene, a diterpene belonging to the clerodane series [58]; isolated for the first time in Stachys rosea (Labiatae) [59], being the present study the first report of this compound in the Sapindaceae family. However, some clerodanes have recently been reported on this family, particularly in the species Dodonaea viscosa [60] [61]. Owing to the little quantity obtained of this compound, no bioassays were developed assessing its activity.…”

Isoprenylated flavonoids and clerodane diterpenoids from Dodonaea viscosa

“…The pro-19S diastereotopic proton, which was ω-coupled ( 4 J = 2.0 Hz) with H-6β, 23 showed correlations with H-1α and H 3 -20, indicating α-and axial orientation for both C-20 and C-19. In addition, the axially 24 except that a methoxy group was evident in 6.…”
