Abstract

Abstract

Phytochemical studies on the fruits of Eucalyptus globulus led to the isolation of twelve compounds. The structures of these compounds were elucidated as: ellagic acid( 1 ), 3-O-methylellagic acid 4′-O-α-rhamnopyranoside( 2 ), valoneic acid dilactone( 3 ), isobiflorin( 4 ), biflorin( 5 ), 8-β-C-glucopyranosyl-5, 7-dihydroxy-2-isobutylchromone( 6 ), 8-β-C-glucopyranosyl-5, 7-dihydroxy-2-isopropylchromone( 7 ), quercetin 3-O-β-D-glucopyranoside( 8 ), quercetin 3-O-β-D-glucuronide-6″-methyl ester( 9 ), (+)-lyoniresin-4-yl β-D-glucopyranoside( 10 ), cypellocarpins A( 11 ), and eucaglobulin 1( 12 ), by means of spectroscopic analyses(ESI-MS, ¹H NMR and ¹³C NMR). Compounds 3-10 were isolated from this plant for the first time.
- Myrtaceae,
