Germacrene A synthase in yarrow (Achillea millefolium) is an enzyme with mixed substrate specificity: gene cloning, functional characterization and expression analysis
Terpenoid synthases constitute a highly diverse gene family producing a wide range of cyclic and acyclic molecules consisting of isoprene (C5) residues. Often a single terpene synthase produces a spectrum of molecules of given chain length, but some terpene synthases can use multiple substrates, producing products of different chain length. Only a few such enzymes has been characterized, but th...
متن کاملAchillinin A, a cytotoxic guaianolide from the flower of Yarrow, Achillea millefolium.
Achillinin A (2β,3β-epoxy-1α,4β,10α-trihydroxyguai-11(13)-en-12,6α-olide, 1), a new guaianolide isolated from the flower of Achillea millefolium, exhibited potential antiproliferative activity to A549, RERF-LC-kj and QG-90 cells with 50% inhibitory concentration (IC(50)) values of 5.8, 10 and 0.31 µM, respectively.
متن کاملDetermination of Carbonic Anhydrase and Level of Zn in the Yarrow (Achillea Millefolium)
The carbonic anhydrase (CA: Carbonate hydrolyase: E.C.4.2.1.1) content from the leaves and flowers of mature yarrow (Achillea millefolium), a plant believed to possess healing qualities, was purified and characterized. The purification levels were 35.58 fold in the leaves and 40.21 fold in the flowers. The optimum temperatures were 25C and 40C for the leaves and flowers, respectively, and optim...
متن کاملCytological investigations and new chromosome number reports in yarrow (Achillea millefolium Linnaeus, 1753) accessions from Iran
In this study, a new chromosome number for Iranian yarrow (Achillea millefolium L.) accessions was reported. Cytological analyses on four Achillea millefolium accessions, indicated that two accessions were diploids (2n=2x=18) and two tetraploids (2n=4x=36). Cluster analysis based on chromosomal characteristics and karyotype asymmetry, categorized the four accessions separated into two groups. I...
متن کاملRadiolabeling of methanol extracts of yarrow (Achillea millefolium l) in rats.
PURPOSE Current study is focused on extraction with methanol, purification, labeling with (131)I using iodogen method of the yarrow plant and investigating in vivo biological activity using biodistribution and imaging studies on healthy animal models. The aim of the study is to contribute plant extracts to discover new drugs in the diagnosis and treatment of several diseases. METHODS Nine fem...
