A new resveratrol trimer from the roots and stems of Vitis wenchowensis.
Phytochemical constituents of Vitis wenchowensis were investigated for the first time. A new resveratrol trimer, wenchowenol (1), was isolated from the roots and stems of Vitis wenchowensis along with four known stilbenoids 2-5. The structure and relative configuration of 1 were established on the basis of spectral evidence, especially HMBC and NOESY experiments. It showed potent antioxidant ac...
متن کاملTermiticidal activity of diterpenes from the roots of Euphorbia kansui.
Five ingenane compounds, 1-5, kansuinins A and B, isolated from Euphorbia kansui, and their derivatives 7 and 9 were tested for termiticidal activity against the Japanese termite, Reticulitermes speratus. At 72 hours after treatment, the ingenane compounds 1 to 5 caused 100% mortality in R. speratus at 50, 25 and 12.5 microg/disk, respectively, except for compound 1, which gave a mortality rate...
متن کاملBioactive 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 کاملStilbenes and a New Acetophenone Derivative from Scirpus holoschoenus
Separation of the extract of the tubers of Scirpus holoschoenus L. (family Cyperaceae), a species easily confused with Juncus plants, afforded 2-prenyl-3,5,4'trimethoxystilbene, 2-prenyl-3-hydroxy-5,4'-dimethoxystilbene, 2-prenyl-3,4'-dihydroxy5-methoxy-stilbene and 3,5,4'-trimethoxystilbene, in addition to a new acetophenone derivative. The isolated compounds were identified on the basis of sp...
متن کاملNew sesquiterpene coumarin from the roots of Ferula latisecta
Objective: The genus of Ferula belongs to the tribe Peucedaneae, subfamily of Apioideae and family of Umbelliferae with 133 species distributed throughout the Mediterranean area and central Asia, especially in the former USSR and neighboring countries such as Iran. The popular Persian name of the most of these species is “Koma”. In this research we tried to isolate and elucidate the structure o...
