Chin J Nat Med. 2018 Jul;16(7):505-508. doi: 10.1016/S1875-5364(18)30086-4.

Abstract

Two new phenolic glycosides, 7S, 8R-urolignoside-9'-O-β-D-glucoside (1) and scrophenoside G (2), were isolated and identified from the seeds of Ginkgo biloba L., a famous traditional medicine and functional food around the world. Their structures were elucidated by spectroscopic methods (1D and 2D NMR, HR-ESI-MS, and CD), and the comparisons of spectroscopic data with the reported values in the literature.

Keywords: Ginkgo biloba; Ginkgo seeds; Lignan glycosides; Phenolic glycosides.
