    Author: Yang XW, Zhang CY, Zhang BG, Lu Y, Luan JW, Zheng QT.
    Journal: J Asian Nat Prod Res; 2009 Aug; 11(8):698-703. PubMed ID: 20183310.
    Abstract:
    A new natural coumarin, angepubebisin (1), and a new furan, angepubefurin (2), together with the five known compounds, umbelliferone, angelol B (3), ulopterol (4), peucedanol (5), and scopoletin, were isolated from the roots of Angelica pubescens Maxim. f. biserrata Shan et Yuan. The structures of angepubebisin (1) and known compounds were determined by spectroscopic methods, including IR, UV, EI-MS, HR-FTICR-MS, 1D-, and 2D-NMR spectral analyses, and angepubefurin (2) was determined by HR-FTICR-MS and X-ray diffraction analyses.
