Studying the Chemical Components and Bioactivities of Rhodomyrtus Tomentosa Extracts

Abstract

Rhodomyrtus tomentosa is a flowering plant belonging to the family of Myrtaceae. This paper uses Rhodomyrtus tomentosa leaves as the sample of the study. Three compounds: hodomyrtosone, combretol and loliolide, were isolated from n-hexan extract (RTH); their structures were identified with proton and carbon-13 NMR spectra. The determining of the total flavonoids (TF) and phenolic (TP) content shows that the ethylacetate extract has higher value for both TF and TP (25.32 mg BHT/g; 60.01 mg GAE/g) compared with the n-hexan extract. 

Keywords 

Rhodomyrtus tomentosa, rhodomyrtosone, combretol, loliolide, total flavonoids content, total phenolic content.
