Two new daucane sesquiterpenoids from Daphne aurantiaca.
Two new daucane sesquiterpenoids 1β,2β-epoxy-10(H)α-dauca-11(12)-ene-7α,14-diol and 1α,2α-epoxy-10(H)α-dauca-11(12)-ene-7α,14-diol were isolated from the plateau medicinal plant Daphne aurantiaca Diels. (Thymelaeceae). Their structures were elucidated by 1D and 2D NMR spectroscopy, as well as HR-ESI-MS data.
متن کاملThree new flavanols from Daphne giraldii.
Three new flavanols, 5-p-hydroxybenzoxy-7-hydroxyl-8-ethoxycarbonyl-( - )-afzelechin (1), 5-p-hydroxybenzoxy-7-(2, 3, 5-trihydroxybenzoxy)-8-ethoxycarbonyl-( - )-afzelechin (2), and 5-p-hydroxybenzoxy-7-(2, 3, 5-trihydroxybenzoxy)-8-methoxycarbonyl-( - )-afzelechin (3), were isolated from Daphne giraldii Nitsche and their structures were elucidated by spectroscopic methods, especially by 2D-NMR...
متن کاملTwo novel innovanoside dimers from Daphne aurantiaca and a concise total synthesis of diinnovanoside A.
Chemical examination of the methanolic extract from the stem bark of Daphne aurantiaca led to the isolation of two innovanoside dimers (1 and 2) with an unusual four-membered cyclobutane ring, together with the isoinnovanoside 3. Their chemical structures and configurations were elucidated by extensive spectral analysis and synthesis.
متن کاملFlavonoids from Daphne aurantiaca and their inhibitory activities against nitric oxide production.
Chemical examination of the methanolic extract from the stem bark of Daphne aurantiaca led to the isolation of three new flavonoids (1-3), and 29 known flavonoids. All 32 compounds were isolated for the first time from Daphne aurantiaca. The isolates were tested for inhibitory activities against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.7 macrophages. Compounds 21...
متن کاملThree New Steroidal Glycosides from the Roots of Cynanchum stauntonii
Three new steroidal glycosides, named as stauntosides L, M, and N (1-3), along with one known C21 steroidal glycoside, anhydrohirundigenin monothevetoside (4), were isolated from the 95% ethanol extract of the roots of Cynanchum stauntonii. The structures of these new compounds were elucidated on the basis of extensive spectroscopic analyses, mainly 1D and 2D NMR, HRESI-MS, and chemical methods.
