| Preparation of [14C]-LabeIled l,2,3,4,6-Penta-0-Gal!oyl-/?-D-Glucose and Related Gallotannins  | | | | Abstract
| [U -14C]-Labelled 1,2,3,4,6-penta-O-galloyl-ß-D-glucose was prepared by photoassimilation of 14C 0 2 with leaves from staghorn sumac (Rhus typhina) in the presence of the herbicide glyphosate. Extracts of the plant material were partitioned against ethyl acetate and chro matographed on Sephadex LH-20, yielding a series o f crude tri-to decagalloylglucoses. The pentagalloylglucose fraction among these was further purified by HPLC to >99% purity and a specific radioactivity of 130 kBq (3.5 fiCi) per fimol. The ratio of the radioactivities in the glucose and galloyl moieties, respectively, suggested a uniform labelling pattern of the product. | | | |
