Cloning and characterization of a β-amyrin synthase gene from the medicinal tree Aralia elata (Araliaceae).
Aralia elata is an important medicinal plant in China; it produces large amounts of oleanane type triterpene saponins. A full-length cDNA encoding β-amyrin synthase (designated as AeAS) was isolated from young leaves of A. elata by reverse transcription-PCR. The full-length cDNA of AeAS was found to have a 2292-bp open reading frame, encoding a protein with 763 amino acid residues. The ded...

Four new saponins, 3-O-[beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranosyl]-16a lpha-hydroxyoleanolic acid 28-O-beta-D-glucopyranosyl ester (called aralia-saponin I), 3-O-[beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranosyl]-16a lpha-hydroxyhederagenin 28-O-beta-D-glucopyranosyl ester (aralia-saponin II), 3-O-[beta-D-glucopyranosyl(1-->3)-beta-D-glucopyranosyl(1-->3)-alpha-L-+ ++arabinopyr...
متن کاملEffect of Treatment with Cyanidin-3-O-β-D-Glucoside on Rat Ischemic/Reperfusion Brain Damage
This study investigated the effect of cyanidin-3-O-β-glucoside on an experimental model of partial/transient cerebral ischemia in the rats in order to verify the effectiveness of both pre- and posttreatments. Cyanidin-3-O-β-glucoside-pretreated rats were injected with 10 mg/Kg i.p. 1 h before the induction of cerebral ischemia; in posttreated rats, the same dosage was injected during reperfusio...
متن کاملMethyl 3-O-α-d-mannopyranosyl β-d-glucopyranoside tetrahydrate
The title compound, C(13)H(24)O(11)·4H(2)O, forms extended hydrogen-bonded networks. These are present between disaccharides, but not as inter-residue hydrogen bonds, as well as to water mol-ecules that in addition form an inter-molecular chain of hydrogen bonds. The conformation of the disaccharide is described by the glycosidic torsion angles ϕ(H) = -34° and ψ(H) = -5°. Macroscopically, the d...
متن کاملGenetic analysis of Aralia cordata Thunb by RAPD.
In the research, genetic analysis of Aralia cordata Thunb. (Araliaceae) was conducted using randomly amplified polymorphism DNA (RAPD). 161 loci were detected with 12 RAPD primers. Percentage of Polymorphic Band (PPB) varied from 34.78% to 63.35%. All the samples were respectively collected from the eight provinces richest in Aralia cordata Thunb resources in China, including Hunan, Yunnan, Zhe...
