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...
متن کاملCarbohydrate specificity of lectins from Boletopsis leucomelas and Aralia cordate.
The carbohydrate specificity of three novel lectins, Boletopsis leucomelas lectin (BLL), Aralia cordate lectin (ACL), and Wasabia japonica lectin (WJL), was examined by frontal affinity chromatography using a panel of fluorescently labeled 47 oligosaccharides. The results indicate that BLL recognizes an agalacto structure of the biantennary chain and its bisecting structure. ACL showed strong a...
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...
متن کاملFour new saponins from the root bark of Aralia elata.
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 کاملSix New Triterpene Derivatives from Aralia chinensis Var. dasyphylloides.
Aralia chinensis var. dasyphylloides is widely distributed in China and used as a traditional herbal medicine for the treatment of digestive and immune system diseases. The present study aimed to search for novel oleanolic-type triterpenoids in low-polarity fractions. Six new triterpene derivatives (1-6), together with two known compounds were isolated from the barks of A. chinensis var. dasyph...
