Bioactive myrsinol diterpenoids from the roots of Euphorbia prolifera.
Ten myrsinol diterpenes, euphorbiaproliferins A-J (1-10), along with nine known analogues (11-19) were isolated from the roots of Euphorbia prolifera. Their structures were elucidated by spectroscopic data analysis (IR, ESIMS, HRESIMS, 1D and 2D NMR), and the structure of 1 was confirmed by X-ray crystallography. The diterpenes showed neuroprotective effects against MPP+-induced neuronal cell d...
متن کاملAbietane-type diterpenoids from the roots of Salvia tebesana
Background and objectives: The genus Salvia is one of the largest genera in the family Lamiaceae and represents approximately 1000 species displaying a remarkable diversity.Salvia tebesana Bunge(Lamiaceae) is an endemic medicinal species that grows wild in center of Iran which is locally named “Maryamgoli Tabasi”.

متن کاملNew Antifeedant Grayanane Diterpenoids from the Flowers of Pieris formosa.
Three new grayanane diterpenoids, pierisoids C‒E (1-3), as well as 10 known ones (4-13), were evaluated from the flowers of Pieris formosa, which is used as an insecticide in rural areas of China. Their structures were elucidated on the basis of extensive 1D and 2D NMR spectroscopic data analyses. Significant antifeedant activity of 1, 3 and 10 against the beet armyworm (Spodoptera exigua) was ...
متن کاملStructure elucidation and chemistry of novel diterpenoids from Euphorbia plants of Iran
Plants of the genus Euphorbia have been investigated for different bioactive natural products. I have isolated several new and bioactive diterpenoids from different species of Euphorbia of Iran with myrsinane type skeleton. The structure of the compounds was determined using high resolution mass spectroscopy, 1 D and 2 D NMR spectral data. The stereochemistry of the diterpenoids was determined ...
