Abstract A new α-tetralonyl glucoside, 6'-O-acetyl-juglanoside E(1), and a new dihydrophaseic acid glucoside, dihydrophaseic acid 1-O-(6-O-acetyl)-glucopyranoside(2), together with two known ones, juglanoside E(3) and dihydrophaseic acid(4), were isolated from the pellicle of the walnut(Juglans regia). The structures of the new compounds were elucidated by comprehensive spectroscopic analysis, including IR, HRESIMS, 1D and 2D NMR data.
