A new flavone O-glycoside and other constituents from wheat leaves (Triticum aestivum L.).
From leaves of Triticum aestivum a new O-glycosylflavone has been isolated together with chlorogenic acid and its 3'-methyl ether and 6 C-glycosylflavones. The structure of the new flavonoid was determined by 1D and 2D NMR techniques and other spectral evidence as 5,7-dihydroxy-3',4',5'-trimethoxyflavone-7-O-beta-rutinoside.
متن کاملCharacterization of soluble acyl-ACP desaturases from Camelina sativa, Macadamia tetraphylla and Dolichandra unguis-cati.
Acyl-acyl carrier protein (ACP) desaturases (EC 1.14.19.2) are soluble enzymes that catalyse the insertion of a double bond into saturated fatty acid bound in saturated acyl chains bound to ACP in higher plants, producing cis-monounsaturated fatty acids. Three types of soluble acyl-ACP desaturases have been described: Δ(9)-acyl-ACP, Δ(6)-acyl-ACP and Δ(4)-acyl-ACP desaturases, which differ in t...
متن کاملA Phenylethanoid Glycoside and Other Constituents from the Fruits of Forsythia koreana
The Oleaceae is a family of medium size with 25 genera and about 600 species. With regard to chemical constituents, it has been quite extensively investigated. It is mainly characterized by the presence of iridoid glucosides and phenylethanoid derivatives in the form of esters and glycosides of tyrosol (p-hydroxyphenyl-ethanol) and in particular the closely related dopaol (3,4-dihydroxyphenyl-e...
متن کاملAlkaloid Constituents of the Amaryllidaceae Plant Amaryllis belladonna L.

Its representative, Amaryllis belladonna, has a geographical distribution covering mainly southern Africa, where it has significant usage in the traditional medicine of the native people. In this study, A. belladonna samples collected in Brazil were examined f...
متن کاملIsolation of a stilbene glycoside and other constituents of Terminalia sericeae.
The ethanol extract of the root bark of Terminalia sericea yielded an unreported stilbene glycoside, 3'5'-dihydroxy-4-(2-hydroxy-ethoxy) resveratrol-3-O-beta-rutinoside (1) together with known compounds resveratrol-3-beta-rutinoside glycoside (2), 3',4,5'-Trihydroxystilbene (resveratrol) (3), triterpenoic acid arjungenin and a mixture of beta-sitosterol and stigmasterol. Structure determination...
