[Identification of chemical component from Ixeris sonchifolia and its injection by HPLC-ESI-MS(n)].[Pubmed:24228586]
Zhongguo Zhong Yao Za Zhi. 2013 Aug;38(16):2675-81.
A rapid analytical method was developed for the identification of components in Ixeris sonchifolia and its injection by HPLC-ESI-MS(n). The characterization of various components was analyzed according to the retention time of reference standard and mass spectrometry information. A profile of I. sonchifolia and its injection constituents was described and a total of three nucleosides, sixteen phenolic acids, seven flavonoids and twelve sesquiterpene lactones were identified or tentatively characterised. Twelve compounds were accurately identified with reference standards. Eleven of them, guanosine, 1-caffeoylquinic acid, 3-caffeoylquinic acid, 4-caffeoylquinic acid, Caffeic anhydride, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, 3-p-coumaroylquinic acid, 3-feruloylquinic acid, 5-p-coumaroylquinic acid and 4-feruloylquinic acid were reported for the first time in I. sonchifolia and its preparations. The structures of five isomers were deduced by theirs mass information and the fragmentation pattern of known compounds. The developed method was useful for the quality control and evaluation of this herb and its preparations. The HPLC-ESI-MS(n) could be a promising tool for the rapid analysis of components from herbal medicines.
Isolation and lipoxygenase-inhibition studies of phenolic constituents from Ehretia obtusifolia.[Pubmed:17191923]
Chem Biodivers. 2005 Jan;2(1):104-11.
The phenolic compounds methyl 2-O-feruloyl-1a-O-vanillactate (1), Caffeic anhydride (2), and trans 4-hydroxycyclohexyl-2-O-p-coumaroyl beta-D-glucopyranoside (3) have been isolated from the AcOEt-soluble fraction of Ehretia obtusifolia, along with methyl rosmarinate (4) and rosmarinic acid (5), which are reported for the first time from this species. Their structures were determined by means of 1D- and 2D-NMR techniques. Compounds 1-5 inhibited lipoxygenase in a concentration-dependent manner, with Ki values ranging from 0.85-57.6 microM. Compounds 1, 2, 4, and 5 showed noncompetitive inhibition, whereas 3 was found to be an uncompetitive inhibitor of lipoxygenase.
