Abstract

Objective: To study the chemical constituents from ethyl acetate extract of Psidium guajava leaves.

Methods: The constituents were separated and purified by silica gel and Sephadex LH-20 column chromatography and their structures were identified on the basis of physicochemical properties and spectral data.

Results: Eleven compounds were isolated and identified as 6,10,14-trimethyl-2-pentadecanone (1), phytyl-acetate (2), cubenol (3), eucalyptin (4), n-docosanoic acid-p-hydroxy-phenethylol ester (5),8-methyl-5,7- dihydroxy-flavonone (6), 6-methyl-5,7-dihydroxy-flavonone (7), betulinic acid (8), carnosol (9), quercetin (10), and 2,4,6-tirhydroxy- 3,5-dimethyl-diphenylketone-4-O-(6′”-O-galloyl)-β-D-glucoside (11).

Conclusion: Compounds 1-9 are isolated from this plant for the first time.

Abstract

Lophostemon suaveolens is a relatively unexplored endemic medicinal plant of Australia. Extracts of fresh leaves of L. suaveolens obtained from sequential extraction with n-hexane and dichloromethane exhibited antibacterial activity in the disc diffusion and MTT microdilution assays against Streptococcus pyogenes and methicillin sensitive and resistant strains of Staphylococcus aureus (minimum bactericidal concentration < 63 μg/mL). The dichloromethane extract and chromatographic fractions therein inhibited nitric oxide in RAW264.7 murine macrophages (IC50 3.7-11.6 μg/mL) and also PGE2 in 3T3 murine fibroblasts (IC50 2.8-19.7 μg/mL). The crude n-hexane, dichloromethane and water extracts of the leaves and chromatographic fractions from the dichloromethane extract also showed modest antioxidant activity in the ORAC assay. GC-MS analysis of the n-hexane fraction showed the presence of the antibacterial compounds aromadendrene, spathulenol, β-caryophyllene, α-humulene and α-pinene and the anti-inflammatory compounds β-caryophyllene and spathulenol. Fractionation of the dichloromethane extract led to the isolation of eucalyptin and the known anti-inflammatory compound betulinic acid.

Abstract

Gradient enhanced nuclear Overhauser effect spectroscopy (GOESY) has been applied in the structural elucidation of five plant secondary metabolites: eucalyptin, arctigenin, 5-geranyloxy-7-methoxycoumarin, 2,6-dihydroxy-4-methoxyisovalerophenone and N-feruloyltyramine. The importance and sensitivity of this technique in structure elucidation of plant secondary metabolites are discussed.
