摘要：

A new phenolic glycoside (E)-4-hydroxycinnamyl alcohol 4-O-(2'-O-beta-D-apiofuranosyl)(1 '' -> 2')-beta-D-glucopyranoside (1) was isolated and identified from Cucumis melo seeds together with benzyl O-beta-D-glucopyranoside (2), 3,29-O-dibenzoylmultiflor-8-en-3 alpha,7 beta, 29-triol (3) and 3-O-p-amino-benzoyl-29-O-benzoylmultiflor-8-en-3 alpha,7 beta, 29-triol (4). Their structures were elucidated by extensive NMR experiments including H-1-H-1 (COSY, TOCSY, ROESY) and H-1-C-13 (HSQC and HMBC) spectroscopy and chemical evidence. The multiflorane triterpene esters were identified as new melon constituents. (C) 2009 Phytochemical Society of Europe. Published by Elsevier B.V. All rights reserved.
