Separation and identification of an abundant trigalloylglucose from special tea genetic resources
Galloylglucoses can extensively and intensively interact with proteins and possess many biological activities and exhibit optimal health benefits. A novel galloylglucose had been observed and separated from fresh shoots of some special tea genetic resources, and was characterized as a trigalloylgluc...

| description | Galloylglucoses can extensively and intensively interact with proteins and possess many biological activities and exhibit optimal health benefits. A novel galloylglucose had been observed and separated from fresh shoots of some special tea genetic resources, and was characterized as a trigalloylglucose isomer with mass parent ion [M-H]− at m/z 635.10 and daughter ions at m/z 483.08, 465.08, 313.02 and 168.98 and with UV absorbance peaks at 221 nm and 278 nm after being measured with UPLC-DAD-MS/MS. The trigalloylglucose was highly purified by semi-preparative chromatography and identified as 1,4,6-tri-O-galloyl-β-glucopyranose (1,4,6-TGG) by 1H-NMR, 13C-NMR, H1-H1 COSY and HMQC. Antioxidant capacity of the 1,4,6-TGG was 2.68−5.77 μmol TEAC/μmol, and significantly higher (42.7%−419.4%) than that of ascorbic acid, but similar to another well-known powerful antioxidant epigallocatechin gallate in tea, indicating that 1,4,6-TGG could, in the future, be applied in the development of functional foods and pharmaceuticals. |
