  Chemical constituents of Tolpis species

  摘要：

  Phytochemical research of two Tolpis species, T. webbii and T. sp., led to the isolation of three new compounds: 2,4'-dihydroxy-4-methoxybenzophenone (1) and the triterpenes 21 alpha, 22 alpha-epoxy-20 alpha-hydroxy-20(30)-dihydrotaraxasterol (2) and 3 beta-hydroxytaraxaster-20-en-30-oic acid (3) together with 16 known compounds. The structures of the new compounds were elucidated by means of extensive IR, NMR, MS and X-ray analysis and by comparison of data reported in the literature. (c) 2009 Elsevier B.V.
