A new phenolic glycoside (E)-4-hydroxycinnamyl alcohol 4-O-(2′-O-β-D-apiofuranosyl)(1″→2′)-β-D-glucopyranoside (1) was isolated and identified from Cucumis melo seeds together with benzyl O-β-D-glucopyranoside (2), 3,29-O-dibenzoylmultiflor-8-en-3α,7β,29-triol (3) and 3-O-p-amino-benzoyl-29-O-benzoylmultiflor-8-en-3α,7β,29-triol (4). Their structures were elucidated by extensive NMR experiments including 1H–1H (COSY, TOCSY, ROESY) and 1H–13C (HSQC and HMBC) spectroscopy and chemical evidence. The multiflorane triterpene esters were identified as new melon constituents.

Abstract

A new phenolic glycoside (E)-4-hydroxycinnamyl alcohol 4-O-(2′-O-β-D-apiofuranosyl)(1″→2′)-β-D-glucopyranoside (1) was isolated and identified from Cucumis melo seeds together with benzyl O-β-D-glucopyranoside (2), 3,29-O-dibenzoylmultiflor-8-en-3α,7β,29-triol (3) and 3-O-p-amino-benzoyl-29-O-benzoylmultiflor-8-en-3α,7β,29-triol (4). Their structures were elucidated by extensive NMR experiments including 1H–1H (COSY, TOCSY, ROESY) and 1H–13C (HSQC and HMBC) spectroscopy and chemical evidence. The multiflorane triterpene esters were identified as new melon constituents.
