1A New Dihydroflavone Glycoside from Glycyrrhiza uralensis显示文摘A new dihydroflavone glycoside was isolated from the underground parts of Glycyrrhiza uralensis. Its structure was elucidated as 7-hydroxyl-4′-O-]3-D-(6″-O-α-hydroxylpropionyl) glucopyranosyl dihydroflavone by spectral methods.HongXiaLIU WenHanLIN JunShanYANG 2004Chinese Chemical Letters2004,15,8:2
2ESI/MS of N-(O,O-Diisopropyl) Phosphoryl Aromatic Amino Acids and their Stability Investigation Using HPLC/UV/ESI/MS显示文摘The full scan ESI/MS and ESI/MS2 of N-(O, O-diisopropyl) phosphoryl aromatic amino acids (DIPPAAAs), N-(O, O-diisopropyl) phosphoryl phenylalanine, N-(O, O-diisopropyl) phosphoryl tryptophan and N-(O, O-diisopropyl) phosphoryl tyrosine, were obtained. The specific ions for them were found. Their stability in the LC mobile phase was investigated using developed HPLC/UV/ESI/MS and the results demonstrated that the DIPPAAAs were stable in the mobile phase (5 mmol/L NH4Ac-MeCN (80:20,v/v, pH7.5) within 48 h.HongXiaLIU ShuShengZHANG JianChenZHANG XiaoYANG LingBoQU YuFenZHAO 2005Chinese Chemical Letters2005,16,5:0
3Direct Observation of Non-covalent Complexes for Phosphorylated Flavonoid-protein Interaction by ESI显示文摘Diethyl flavon-7-yl phosphate was synthesized by modified Atheron-Todd reaction. The result of ESI shows that the phosphated flavonoids possess stronger binding affinities toward proteins such as myoglobin, insulin and lysozyme and are easier to form the non-covalent complexes with them.XiaoLanCHEN TingZHANG HongXiaLIU LingBoQU YouZhuYU YuFenZHAO 2004Chinese Chemical Letters2004,15,3:0
