Abstract

Abstract: Phytochemical investigation of Pholidota pallida Lindl. led to the isolation of eleven compounds 1–11 (coelonin 1, lusianthridin 2, flavanthrin 3, batatasin-Ⅲ 4, 3′, 5-dihydroxy-2-(4-hydroxybenzyl)-3-methoxybibenzyl 5, gigantol 6, 3-[2-(3-hydroxyphenyl) ethyl]-2, 4-bis[(4-hydroxyphenyl) methyl]-5-methoxyphenol 7, hydroxytyrosyl butyrate 8, (24R)-ethylcholest-5-en-3-ol-7-one 9, taraxerone 10, friedelin 11 ) including three phenanthrenes 1–3, four bibenzyls 4–7, one hydroxytyrosyl 8, one steroid 9 and two terpenoids 10–11 . The structures of these compounds were elucidated by spectroscopic analyses. This is the first report of isolation of compounds 1–11 from Pholidota pallida and compounds 5 and 8–11 within genus Pholidota . Compound 8 is a new natural product, isolated from a natural source for the first time. Furthermore, the chemotaxonomic significance of the isolates was also discussed. Graphical abstract: Image 1 Highlights: A phytochemical investigation of Pholidota pallida has been carried out. Eleven compounds (1–11) were first isolated from Pholidota pallida. Five compounds were first isolated from genus Pholidota. Hydroxytyrosyl butyrate (8) is a new natural product, isolated from a natural source for the first time. These compounds provide evidence for chemotaxonomic studies of Pholidota pallida and genus Pholidota.
