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.
